1. Key Takeaways

The 20 May 2016 Tsai Inaugural Strategic-Reorientation Naming. In her inaugural address delivered on 20 May 2016 at the Office of the President in Taipei, President Tsai Ing-wen named Southeast Asia, South Asia, and Australia–New Zealand as the strategic-reorientation theatre toward which Taiwan would re-articulate its economic-diplomatic architecture, framing the Xinnan Zhengce (新南向政策, New Southbound Policy) as a people-centred and bilateral-cooperation-based alternative to the post-2008 Ma-era cross-Strait economic-integration framing. The inaugural-address naming was the political-rhetorical anchor for the subsequent administrative-operationalisation sequence that built the eighteen-target-country bilateral-engagement architecture over the August–November 2016 period. The Tsai inaugural framing distinguished the New Southbound from the earlier 1993 Lee-era and 2002 Chen-era Go South (南向, Nán Xiàng) policies by emphasising the multi-dimensional human-and-cultural-exchange architecture rather than the predominantly investment-flow-oriented earlier instantiations.
The 16 August 2016 Office of Trade Negotiations Establishment. Under Premier Lin Chuan (林全), the Executive Yuan established the Office of Trade Negotiations (OTN, 行政院經貿談判辦公室) by Executive Yuan order issued 16 August 2016 as a dedicated cabinet-level trade-policy-coordination body reporting directly to the Vice Premier. The inaugural OTN Chief Negotiator John Deng (鄧振中) — previously Minister of Economic Affairs under the post-2014 reshuffle and subsequently MOEA Minister 2014–2016 — was appointed to coordinate the New Southbound bilateral-engagement architecture, the post-2016 trade-policy-architecture diversification, and the eventual CPTPP-application preparation. The OTN's establishment marked a architectural innovation in Taiwan's executive-branch trade-policy coordination, providing a single locus for the cross-MOEA-MOFA-MOE-Tourism-Bureau coordination that the New Southbound architecture required.
The 5 September 2016 Executive Yuan New Southbound Policy Promotion Plan Release. On 5 September 2016, the Executive Yuan formally released the Xinnan Zhengce Tuidong Jihua (新南向政策推動計畫, New Southbound Policy Promotion Plan), the foundational policy document articulating the eighteen-target-country geography, the four-pillar architecture (economic-and-trade cooperation; talent exchange; resource sharing; regional linkages), and the cross-ministerial coordination framework. The subsequent New Southbound Policy Work Plan, released in November 2016, provided the disaggregated implementation-architecture with year-by-year benchmarks and country-by-country bilateral-engagement priorities. The 5 September 2016 release date is the operative administrative-baseline for the New Southbound architecture and the reference point against which subsequent implementation is assessed.
The Eighteen-Target-Country Geographic Architecture. The New Southbound architecture targets eighteen countries across three sub-regional clusters: the ten ASEAN members (Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand, Vietnam); the six South Asian states (Bangladesh, Bhutan, India, Nepal, Pakistan, Sri Lanka); plus Australia and New Zealand. The eighteen-country scope was deliberately broader than the earlier 1993 Lee-era and 2002 Chen-era Go South policies, which had focused predominantly on Southeast Asia; the addition of South Asia (particularly India) and Australia–New Zealand reflected the post-2016 emphasis on diversification across multiple sub-regional economic-architectures and the recognition that Taiwan's bilateral-engagement architecture required a wider geographic foundation. Critically, none of the eighteen target countries maintains formal diplomatic relations with the Republic of China — all operate under the post-1971 One-China-framework constraint that requires Taiwan's bilateral-engagement architecture to operate through informal representative office (代表處) and trade-office channels.
The Four-Pillar Architectural Innovation. The New Southbound architecture's four-pillar structure was a innovation relative to earlier Go South iterations: Pillar 1 (economic-and-trade cooperation) covered bilateral investment agreements, industrial-cooperation platforms, and free-trade-agreement negotiation; Pillar 2 (talent exchange) covered the Taiwan Scholarship Programme, the Huayu Enrichment Scholarship, and Mandarin-language teaching; Pillar 3 (resource sharing) covered medical cooperation, agricultural cooperation, and ICT cooperation; Pillar 4 (regional linkages) covered multilateral-platform participation and regional-value-chain integration. The four-pillar framing recognised that Taiwan's bilateral-engagement architecture with the eighteen target countries could not rely solely on trade-and-investment flows but required a multi-dimensional cultural-educational-medical-platform architecture that compensated for the absence of formal diplomatic relations.
The 2016–2019 First-Term Trade-and-Investment Implementation Record. Across the 2016–2019 first-term implementation window, the Taiwan-New-Southbound bilateral-trade-flow trajectory showed substantial year-over-year growth, with the cumulative Taiwan-New-Southbound bilateral-trade-flow exceeding US$100 billion by 2018 [TBD-VERIFY: precise cumulative bilateral-trade-flow figures 2016–2019]. The outbound-investment flow trajectory included the post-2017 surge in Vietnam (textiles, ICT manufacturing), Indonesia (petrochemicals, electronics), and Thailand (automotive components, electronics); the post-2018 Bilateral Investment Agreement signings with India (16 December 2018 [TBD-VERIFY]) and the renewal of bilateral-investment-agreements with the Philippines (2017 [TBD-VERIFY]) and Vietnam (2019 [TBD-VERIFY]). The One Country, One Centre (一國一中心) medical-cooperation architecture, launched in 2017, established Taiwan-led medical-cooperation hubs in Indonesia, the Philippines, Vietnam, Thailand, Malaysia, India, and Myanmar.
The 2016–2019 Tourism-and-Education Implementation Record. The post-2016 visa-easing architecture provided substantial impetus to the New Southbound tourism-flow architecture: visa-waiver for Thailand and Brunei nationals (2016); visa-waiver expansion to the Philippines (2017); the subsequent Indonesia e-Visa architecture (post-2020). The New Southbound tourist-arrival trajectory 2015–2019 showed substantial growth from Vietnam, Thailand, the Philippines, and India, with the total New Southbound tourist arrivals reaching multiple million-tourist levels by 2019 [TBD-VERIFY: precise tourist-arrival figures 2016–2019]. The Taiwan Scholarship Programme and the Huayu Enrichment Scholarship, with New Southbound-disaggregated allocations, supported a growing population of New Southbound students at Taiwanese higher-education institutions, with the New Southbound student-population reaching tens of thousands by the end of the 2019 academic year [TBD-VERIFY: precise New Southbound student-population figures 2016–2019].
The 2020 COVID-19 Disruption and the 2020–2023 Partial Recovery. The post-March 2020 international-travel collapse, consequent to the global COVID-19 pandemic, disrupted the New Southbound tourism-flow architecture, with the New Southbound tourist-arrival figures collapsing to near-zero across April 2020 – April 2022. The medical-cooperation pillar, however, was re-articulated during the COVID-19 era through the post-March 2020 mask diplomacy architecture (Taiwan's donation of millions of medical masks to the New Southbound countries), the post-2021 vaccine-cooperation architecture, and the post-2022 medical-supply-chain-resilience architecture. The trade-and-investment-flow pillar continued through the COVID-19 era at substantial levels, with the New Southbound bilateral-trade-flow continuing to grow notwithstanding the tourism-flow disruption.
The 23 September 2021 CPTPP Application. On 23 September 2021, Taiwan formally submitted its application to accede to the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), the eleven-member Asia-Pacific free-trade architecture signed Santiago 8 March 2018 and entered into force 30 December 2018. The Taiwan application was submitted one week after the PRC's 16 September 2021 CPTPP application, producing a parallel-application dynamic that has continued through 2026. The CPTPP application is the most consequential multilateral-trade-architecture move within the New Southbound framework, since six of the eighteen New Southbound target countries (Singapore, Malaysia, Vietnam, Brunei, Australia, New Zealand) are CPTPP members and a successful Taiwan accession would re-architect the bilateral-trade-architecture with these six countries. The application's continuing-pending status through 2026 reflects both the CPTPP Commission consensus-requirement architecture and the parallel PRC-application complication.
The Post-2020 Tsai Second-Term Re-Articulation and Resilient Supply Chain Logic. Across the post-20 May 2020 Tsai second-term window, the New Southbound architecture was re-articulated under the post-2020 Resilient Supply Chain (供應鏈韌性, Gōngyìngliàn Rènxìng) framing, which emphasised the cross-Strait-decoupling logic of the bilateral-engagement architecture and the cross-reference with the post-2020 US-led Friend-Shoring and De-Risking frameworks. The post-2022 Indo-Pacific Economic Framework (IPEF) Taiwan-exclusion question — the Biden-administration decision not to include Taiwan in the May 2022 IPEF launch despite the 22 May 2022 US-Taiwan Initiative on 21st Century Trade parallel-architecture launch — was a setback that the New Southbound architecture was tasked with compensating for, through both intensified bilateral engagement and the continuing CPTPP-application track.
The Post-20 May 2024 Lai-Era Continuation. Across the post-20 May 2024 Lai Ching-te inaugural window, the New Southbound architecture has been continued under Vice Premier Cheng Li-chiun (鄭麗君) and the restructured Office of Trade Negotiations. The Lai administration's 2024 New Southbound Policy Re-Articulation Plan preserves the eighteen-target-country geography and the four-pillar architecture while introducing post-2024 emphases on semiconductor-supply-chain integration (particularly with India, Vietnam, and Indonesia), digital-economy cooperation, and the post-2022 cross-Strait-decoupling logic continuation. The post-2024 architecture is broadly continuous with the post-2020 Tsai second-term re-articulation rather than constituting a policy-reset.
The Post-April 2025 Trump-2 Reciprocal-Tariff Architecture and the 2025–2026 Recalibration. The 2 April 2025 Trump-2 Liberation Day reciprocal-tariff announcement included a 32 per cent reciprocal-tariff rate applied to Taiwan [TBD-VERIFY: precise April 2025 reciprocal-tariff rate for Taiwan and post-9 April 2025 90-day-pause and subsequent negotiation-period architecture]. The post-April 2025 OTN tariff-negotiation response under Chief Negotiator Yang Jen-ni and Vice Premier Cheng Li-chiun has re-engaged with the New Southbound architecture in light of the new tariff environment, with the bilateral-trade-architecture diversification logic gaining renewed salience as the US-export-architecture faces continuing tariff-uncertainty. The 2025–2026 New Southbound trajectory is being recalibrated against the post-April 2025 trade-architecture transformation, with the forward-trajectory question of whether the New Southbound can compensate for any sustained US-tariff-induced trade-architecture disruption emerging as a central post-2025 strategic-architecture question.

2. The Pre-2016 Antecedents — The 1993 Lee Teng-hui First Go South, the 2002 Chen Shui-bian Second Go South, and the Pre-2016 ASEAN-Investment Baseline

2.1 The 1993 Lee Teng-hui First Nán Xiàng Policy

The post-2016 New Southbound architecture has antecedents in Taiwan's earlier post-Cold-War southbound-policy iterations. The first iteration, launched in 1993–1994 under President Lee Teng-hui (李登輝, 1923–2020; president 1988–2000) and Premier Lien Chan (連戰, 1936–; premier 1993–1997), was articulated as the Nán Xiàng Zhèngcè (南向政策, Go South Policy). The policy emerged in the context of two parallel post-1987 dynamics: first, the post-1987 lifting of martial law and the consequent post-1990 explosive growth in Taiwanese outbound investment to mainland China, which created concern in the Lee administration about excessive cross-Strait economic dependence; and second, the early-1990s post-Cold-War ASEAN economic-architecture transformation, with the 1992 ASEAN Free Trade Area (AFTA) signing in Singapore providing a regional-architecture into which Taiwanese investment could be channelled.

The 1993 Nán Xiàng Zhèngcè was structured primarily as an outbound-investment-channelling instrument, with the Taiwan government providing incentives for Taiwanese manufacturers to invest in ASEAN countries (particularly Indonesia, Malaysia, Thailand, the Philippines, and Vietnam) rather than mainland China. The instruments included the Taiwan-ASEAN Industrial-Cooperation Fund, the Vietnam-Taiwan Industrial Park (established 1993 in Đồng Nai province), and the bilateral-investment-agreement framework with the Philippines (signed February 1992) and Indonesia (signed November 1990) [TBD-VERIFY: precise pre-1996 Taiwan-Philippines and Taiwan-Indonesia bilateral-investment-agreement signing dates]. The Vietnam-Taiwan Industrial Park, in particular, became a substantial Taiwanese-investment hub, with the Vietnam Taiwan cumulative investment reaching multi-billion-dollar levels by the late 1990s.

The 1995–1996 Third Strait Crisis, however, complicated the 1993 Nán Xiàng Zhèngcè architecture. The 21 July 1995 – 23 March 1996 PRC missile-test and military-exercise sequence in the Taiwan Strait, conducted in response to the 9 June 1995 Lee Teng-hui Cornell University visit, produced both a depreciation of Taiwanese cross-Strait investment confidence and a parallel intensification of Lee-era concerns about cross-Strait economic dependence. In the post-1996 first-direct-presidential-election context, however, the Nán Xiàng Zhèngcè lost institutional priority as the post-1996 cross-Strait economic-architecture stabilised and Taiwanese outbound investment to mainland China resumed its prior-trajectory growth.

2.2 The 2002 Chen Shui-bian Second Nán Xiàng Policy

The second iteration was launched in 2002 under President Chen Shui-bian (陳水扁, 2000–2008) and Premier Yu Shyi-kun (游錫堃, premier 2002–2005). The 2002 Nán Xiàng Zhèngcè re-emerged in the context of two parallel post-2000 dynamics: first, the post-2001 mainland-China WTO accession (PRC accession 11 December 2001; Taiwan's parallel accession as Taiwan, Penghu, Kinmen and Matsu Separate Customs Territory on 1 January 2002), which re-architected the cross-Strait trade-and-investment architecture; and second, the post-2001 PRC GDP-growth acceleration, which intensified Chen-administration concerns about cross-Strait economic-dependence asymmetries.

The 2002 Nán Xiàng Zhèngcè was, however, constrained by the post-2000 cross-Strait economic-integration dynamic. Despite the formal policy re-launch, Taiwanese outbound investment to mainland China continued its post-2000 growth trajectory, with the cumulative Taiwanese-investment-to-PRC reaching levels that substantially exceeded the cumulative Taiwanese-investment-to-ASEAN across the entire post-2002 Chen-era window. The pre-2008 cross-Strait investment cap (40 per cent of the investing firm's net worth — a regulatory ceiling imposed by the post-2002 Cross-Strait Relations Act implementation regulations) was repeatedly criticised by Taiwanese manufacturing interests as constraining cross-Strait competitiveness, and the post-2008 Ma-era liberalisation removed the 40-per-cent cap and further accelerated the cross-Strait integration dynamic.

The 2002 Nán Xiàng Zhèngcè did, however, produce bilateral-engagement architecture innovations. The 2002 Taiwan-India Economic Forum (the precursor to the post-2018 Bilateral Investment Agreement architecture); the 2003–2005 expansion of Taiwan Scholarship Programme awards to South Asian and Southeast Asian students; and the early-2000s expansion of the Taiwan External Trade Development Council (TAITRA, 中華民國對外貿易發展協會) representative-office network across the ASEAN and South Asian capitals were 2002–2008 architectural-build-out moves that subsequently provided the institutional foundation for the post-2016 New Southbound architecture.

2.3 The 2008–2016 Ma-Era Cross-Strait Integration Peak and the Pre-2016 ASEAN-Investment Baseline

Across the 2008–2016 Ma Ying-jeou administration, the cross-Strait economic-integration dynamic reached its peak under the post-2010 ECFA architecture and the 2008–2015 twenty-three cross-Strait agreements (covered in detail in TW-E-01). The Ma-era cross-Strait integration produced Taiwanese-outbound-investment-to-PRC flows, with the cumulative Taiwanese investment in mainland China reaching levels widely reported in the literature as exceeding US$190 billion by 2016 [TBD-VERIFY: precise cumulative Taiwanese-PRC investment figures 2008–2016]. The cross-Strait trade-flow architecture during the Ma era reached a peak in 2014, with the bilateral cross-Strait trade-flow reaching approximately US$198 billion in 2014 [TBD-VERIFY: precise 2014 cross-Strait bilateral-trade-flow figure].

The post-2014 Sunflower Movement (covered in TW-B-05) produced a partial inflection in the cross-Strait economic-integration dynamic. The 18 March – 10 April 2014 Legislative Yuan occupation suspended the ratification of the 21 June 2013 Cross-Strait Services Trade Agreement (CSSTA), and the subsequent Cross-Strait Agreements Oversight Bill (兩岸協議監督條例) draft-legislation process — which proceeded through multiple draft iterations across 2014–2016 without final-passage — created cross-Strait economic-architecture uncertainty. The post-2014 cross-Strait integration plateau, combined with the 2014–2016 PRC economic-growth-rate moderation, produced the political-economic-architecture conditions within which the post-2016 New Southbound reorientation became politically and economically viable.

By the end of the Ma administration in May 2016, the pre-2016 Taiwan-ASEAN bilateral-trade-and-investment baseline was substantial but substantially smaller than the cross-Strait baseline. Cumulative Taiwanese investment in the ten ASEAN countries reached approximately US$87 billion by 2015 [TBD-VERIFY: precise cumulative Taiwanese-ASEAN investment figures 2015], with the largest cumulative-investment shares in Vietnam (textiles, electronics, footwear), Indonesia (petrochemicals, electronics), and Thailand (automotive, electronics). The bilateral Taiwan-ASEAN trade-flow in 2015 reached approximately US$92 billion, representing approximately 18 per cent of Taiwan's total trade-flow — substantial but substantially below the cross-Strait trade-flow share of approximately 26 per cent in the same year [TBD-VERIFY: precise 2015 Taiwan-ASEAN bilateral-trade-flow and cross-Strait bilateral-trade-flow shares]. The post-2016 New Southbound architecture was thus building from a substantial but secondary pre-existing trade-and-investment-architecture baseline.

3. The 20 May 2016 Tsai Inaugural Naming and the August–September 2016 Operationalisation

3.1 The 20 May 2016 Tsai Inaugural Address Strategic-Reorientation Naming

President Tsai Ing-wen delivered her inaugural address on 20 May 2016 at the Office of the President in Taipei, marking the formal commencement of the post-2016 DPP federal-government era and the second post-1996 KMT-to-DPP transition (after the 2000 Chen Shui-bian first transition). The inaugural address articulated a cross-Strait position — committing to "the existing political foundations" of cross-Strait relations including "the historical fact of the 1992 meeting" without endorsing the specific 1992 Consensus (Jiu'er Gongshi) framing — and a economic-strategic-architecture re-articulation.

The economic-strategic-architecture paragraph of the inaugural address explicitly named Southeast Asia, South Asia, and Australia–New Zealand as the strategic-reorientation theatre, framing the New Southbound policy as a people-centred and bilateral-cooperation-based alternative to the post-2008 Ma-era cross-Strait economic-integration framing. The inaugural-address language — using formulations such as "expand cooperation with our neighbours" and "deepen the people-to-people connections across Southeast Asia, South Asia, Australia, and New Zealand" [TBD-VERIFY: precise inaugural-address language on the New Southbound reorientation] — established the political-rhetorical anchor for the subsequent administrative-operationalisation sequence.

The Tsai inaugural framing distinguished the post-2016 New Southbound from the earlier 1993 Lee-era and 2002 Chen-era Go South policies in three respects. First, the geographic scope was broader, including South Asia (particularly India) and Australia–New Zealand alongside ASEAN. Second, the architectural framing was multi-dimensional, with the four-pillar architecture (economic-and-trade; talent exchange; resource sharing; regional linkages) explicitly emphasised in the post-September 2016 policy documentation. Third, the political-rhetorical framing emphasised the people-centred and bilateral-cooperation character of the architecture, distinguishing it from the predominantly investment-flow-oriented framings of the earlier iterations.

3.2 The 16 August 2016 Office of Trade Negotiations Establishment

Under Premier Lin Chuan (林全, premier 20 May 2016 – 8 September 2017), the Executive Yuan established the Office of Trade Negotiations (OTN, 行政院經貿談判辦公室) by Executive Yuan order issued 16 August 2016. The OTN was structured as a dedicated cabinet-level trade-policy-coordination body reporting directly to the Vice Premier (then Vice Premier Lin Hsi-yao 林錫耀 [TBD-VERIFY: precise Vice Premier holding the OTN coordination portfolio in August 2016]), with a Chief Negotiator at minister-without-portfolio rank.

The inaugural OTN Chief Negotiator John Deng (鄧振中, 1951–) — previously Minister of Economic Affairs under the Ma administration 2014–2016 — was appointed to coordinate the New Southbound bilateral-engagement architecture, the post-2016 trade-policy-architecture diversification, and the eventual CPTPP-application preparation. The Deng appointment was significant: as a senior MOEA official with continuity across the Ma-Tsai transition, Deng provided both the technical-trade-policy expertise and the cross-administration institutional-memory that the New Southbound architecture's complex multi-ministerial coordination required.

The OTN's establishment marked a architectural innovation in Taiwan's executive-branch trade-policy coordination. Prior to August 2016, Taiwan's trade-policy coordination was distributed across MOEA (with primary responsibility through the Bureau of Foreign Trade), MOFA (through the Department of East Asian and Pacific Affairs and the Department of International Organizations), and the Executive Yuan Secretariat. The OTN provided a single locus for the cross-MOEA-MOFA-MOE-Tourism-Bureau coordination that the New Southbound architecture required, with explicit authority to convene cross-ministerial coordination meetings and to issue cross-ministerial implementation directives.

3.3 The 5 September 2016 Executive Yuan New Southbound Policy Promotion Plan

On 5 September 2016, the Executive Yuan formally released the Xinnan Zhengce Tuidong Jihua (新南向政策推動計畫, New Southbound Policy Promotion Plan), the foundational policy document articulating the eighteen-target-country geography, the four-pillar architecture, and the cross-ministerial coordination framework. The 5 September 2016 release was preceded by a multi-month consultation process across the post-May 2016 inaugural window, with input from MOEA, MOFA, MOE, MOHW, the Tourism Bureau, the Council of Agriculture, and the TaiwanICDF.

The Tuidong Jihua document articulated the four-pillar architecture in detail. Pillar 1 (economic-and-trade cooperation, 經貿合作) emphasised bilateral investment agreements, industrial-cooperation platforms, free-trade-agreement negotiation, and the development of integrated value-chain architecture. Pillar 2 (talent exchange, 人才交流) emphasised the Taiwan Scholarship Programme, the Huayu Enrichment Scholarship, Mandarin-language teaching deployment, professional-training cooperation, and the Taiwan-Connection Programme (台灣連結計畫) alumni-network architecture. Pillar 3 (resource sharing, 資源共享) emphasised medical cooperation (subsequently operationalised as the One Country, One Centre architecture), agricultural cooperation (technology transfer, joint-venture agricultural-investment), and ICT cooperation. Pillar 4 (regional linkages, 區域鏈結) emphasised multilateral-platform participation, regional-value-chain integration, and bilateral think-tank dialogue.

The subsequent New Southbound Policy Work Plan (新南向政策工作計畫), released in November 2016, provided the disaggregated implementation-architecture with year-by-year benchmarks and country-by-country bilateral-engagement priorities. The Work Plan identified specific bilateral-engagement priority countries within the eighteen-country target set: Vietnam, Indonesia, and the Philippines as the first-tier ASEAN-engagement priorities; Thailand and Malaysia as the second-tier ASEAN-engagement priorities; India as the predominant South Asian-engagement priority; and Australia and New Zealand as the Oceania-engagement priorities. The first-tier-country prioritisation reflected both pre-existing Taiwanese-investment baselines and the post-2016 strategic-engagement priorities.

3.4 The November 2016 Work Plan Architecture and the Cross-Ministerial Coordination Mechanism

The November 2016 Work Plan established the cross-ministerial coordination mechanism that subsequently structured the New Southbound implementation architecture across the 2016–2024 Tsai era. The mechanism included three principal coordination layers: first, the OTN-coordinated cross-ministerial implementation working group, meeting monthly to review implementation progress and resolve cross-ministerial coordination questions; second, the Executive Yuan-level New Southbound coordination meeting, convened quarterly under the Vice Premier; third, the country-by-country bilateral-engagement task forces, established for the first-tier and second-tier priority countries, each chaired by a designated MOEA or MOFA senior official.

The post-November 2016 implementation architecture was subsequently augmented by two parallel architectural innovations. First, the New Southbound Talent-Development Programme (新南向人才發展計畫), launched in 2017 under MOE coordination, which expanded the Taiwan Scholarship Programme and the Huayu Enrichment Scholarship allocations to New Southbound students. Second, the New Southbound Medical-Cooperation Architecture — the One Country, One Centre framework, launched in 2017 under MOHW coordination, which established Taiwan-led medical-cooperation hubs in Indonesia, the Philippines, Vietnam, Thailand, Malaysia, India, and Myanmar.

4. The Eighteen-Target-Country Architecture — The Ten ASEAN Members, the Six South Asian States, and Australia–New Zealand

4.1 The Ten ASEAN Member Target Countries

The first sub-regional cluster of the eighteen-target-country architecture is the ten ASEAN members: Brunei Darussalam, Cambodia, Indonesia, Lao PDR, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Vietnam. The ASEAN cluster constitutes the historically central focus of Taiwan's southbound-policy architecture, with the cumulative Taiwanese investment in ASEAN reaching approximately US$87 billion by 2015 and the bilateral Taiwan-ASEAN trade-flow reaching approximately US$92 billion in 2015 [TBD-VERIFY: precise cumulative ASEAN investment and bilateral-trade-flow figures 2015].

Within the ASEAN cluster, Taiwan maintains its largest bilateral economic relationships with Vietnam, Indonesia, the Philippines, Thailand, Malaysia, and Singapore. Vietnam — with which Taiwan maintains a substantial Taiwanese-manufacturing baseline (textiles, footwear, electronics, ICT) dating to the 1993 Lee-era Vietnam-Taiwan Industrial Park — is the largest Taiwanese-investment destination within ASEAN, with cumulative Taiwanese investment exceeding US$30 billion by 2024 [TBD-VERIFY: precise cumulative Taiwanese-Vietnam investment figures 2024]. The post-2016 New Southbound architecture has intensified the Taiwan-Vietnam bilateral-engagement architecture, with the 2019 renewal of the bilateral investment agreement (BIA), the post-2018 ICT-manufacturing investment surge (driven in part by the post-2018 US-China trade-war reshoring dynamic), and the post-2020 semiconductor-and-electronics-supply-chain integration.

Indonesia is the second-largest Taiwanese-investment destination within ASEAN, with cumulative Taiwanese investment exceeding US$20 billion by 2024 [TBD-VERIFY: precise cumulative Taiwanese-Indonesia investment figures 2024], concentrated in petrochemicals (including the substantial Formosa Plastics Group post-2015 Java investments), electronics, footwear, and food processing. The post-2016 New Southbound architecture has emphasised the Taiwan-Indonesia bilateral-engagement architecture through both the One Country, One Centre medical-cooperation hub (located in Jakarta), the post-2020 Indonesia e-Visa architecture for Indonesian travel to Taiwan, and the post-2022 Indonesian migrant-worker cooperation framework.

The Philippines is the third-largest Taiwanese-investment destination within ASEAN within the New Southbound architecture, with substantial bilateral-engagement intensification post-2016 driven by both the geographic proximity (the Philippines northernmost-island Batanes is approximately 150 kilometres from southern Taiwan), the substantial Filipino migrant-worker population in Taiwan, and the 2017 visa-waiver implementation. The post-2017 One Country, One Centre medical-cooperation hub in Manila has expanded the Taiwan-Philippines medical-cooperation architecture.

Thailand and Malaysia represent the second-tier ASEAN-engagement priorities within the New Southbound architecture, with both featuring substantial pre-2016 Taiwanese-investment baselines (predominantly in automotive components, electronics, and consumer-goods manufacturing) and post-2016 bilateral-engagement architecture intensification. The 2016 visa-waiver for Thai and Bruneian nationals — implemented post-1 August 2016 [TBD-VERIFY: precise implementation date of the 2016 Thailand visa-waiver] — has expanded the bilateral tourism-flow architecture. Singapore, despite being the smallest ASEAN member by population, is a substantial Taiwanese-investment destination (financial services, biotechnology, ICT) and the Taiwan-Singapore Economic Partnership Agreement (ASTEP, signed 7 November 2013 and entered into force 19 April 2014 — Taiwan's first FTA-equivalent agreement with an ASEAN country) provides the formal-trade-architecture foundation for the bilateral-engagement.

The smaller ASEAN economies (Brunei, Cambodia, Laos, Myanmar) feature substantially smaller Taiwanese-investment baselines, though the post-2016 New Southbound architecture has expanded the bilateral-engagement architecture across all four countries through targeted economic-and-trade cooperation, education exchange, and medical-cooperation (with Myanmar specifically included in the One Country, One Centre architecture).

4.2 The Six South Asian Target States

The second sub-regional cluster of the eighteen-target-country architecture is the six South Asian states: Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka. The South Asian cluster represents a geographic expansion relative to the earlier 1993 and 2002 Go South iterations, reflecting the post-2016 strategic-architecture emphasis on diversification across multiple sub-regional economic-architectures.

India is the predominant South Asian-engagement priority within the New Southbound architecture, with the post-2016 Taiwan-India bilateral-engagement architecture intensifying across multiple dimensions. The 16 December 2018 Bilateral Investment Agreement signing [TBD-VERIFY: precise signing date of the post-2016 Taiwan-India BIA — the post-2018 Taiwan-India BIA is widely reported as the most consequential post-2016 New Southbound bilateral-agreement signing] established the formal-trade-architecture foundation. The post-2018 Taiwan-India ICT and semiconductor-manufacturing cooperation has accelerated under both the post-2018 US-China trade-war reshoring dynamic and the post-2022 India Semiconductor Mission (announced December 2021 with US$10 billion semiconductor-incentive package). The post-2022 Foxconn-Vedanta semiconductor-fab proposal (announced February 2022, subsequently dissolved July 2023), the post-2023 PSMC-Tata semiconductor-fab proposal (announced February 2024 for a US$11 billion fab in Dholera, Gujarat) [TBD-VERIFY: precise PSMC-Tata fab investment announcement date and figures], and other post-2022 Taiwan-India semiconductor-cooperation initiatives have re-architected the bilateral-engagement architecture.

The smaller South Asian states (Bangladesh, Bhutan, Nepal, Pakistan, Sri Lanka) feature substantially smaller Taiwanese-engagement baselines, with the post-2016 New Southbound bilateral-engagement architecture focused predominantly on education exchange (Taiwan Scholarship Programme allocations), medical cooperation (with the post-2018 expansion of medical-cooperation hubs to additional South Asian countries [TBD-VERIFY: precise expansion of One Country, One Centre architecture to South Asian countries beyond India]), and targeted economic-and-trade cooperation. Bhutan, in particular, has smaller bilateral-engagement architecture given both the small Bhutanese economy and Bhutan's foreign-policy constraints under the post-2007 Bhutan-India relationship framework.

4.3 Australia and New Zealand

The third sub-regional cluster of the eighteen-target-country architecture is the Australia–New Zealand pair. Both Australia and New Zealand are CPTPP members (Australia and New Zealand both ratified CPTPP among the first six ratifying members, with the agreement entering force on 30 December 2018), substantial Taiwanese-trade partners (cumulative Taiwan-Australia trade-flow reaching approximately US$17 billion in 2024 [TBD-VERIFY: precise 2024 Taiwan-Australia bilateral-trade-flow figures]), and substantial Taiwanese-student-population host countries.

The post-2016 Taiwan-Australia bilateral-engagement architecture has expanded across multiple dimensions: the Taiwan-Australia Indigenous Cooperation Programme (acknowledging the parallel indigenous-rights architectures across the two countries); the post-2018 Taiwan-Australia agricultural-cooperation framework (substantial post-2020 Australian beef and dairy-product export to Taiwan); the post-2022 Taiwan-Australia critical-mineral cooperation framework (responding to the post-2022 critical-mineral-supply-chain diversification dynamic). The Taiwan-New Zealand Agreement on Economic Cooperation (ANZTEC), signed 10 July 2013 and entered into force 1 December 2013 [TBD-VERIFY: precise ANZTEC signing and entry-into-force dates] — Taiwan's first FTA-equivalent agreement with a developed-economy partner — provides the formal-trade-architecture foundation for the Taiwan-New Zealand bilateral-engagement.

4.4 The Absence of Formal Diplomatic Relations and the Representative-Office Architecture

Critically, none of the eighteen New Southbound target countries maintains formal diplomatic relations with the Republic of China. All eighteen target countries operate under the post-1971 One-China-framework constraint that requires Taiwan's bilateral-engagement architecture to operate through informal representative office (代表處) channels rather than formal embassy channels. Taiwan's representative-office network across the eighteen target countries is structured under the Taipei Economic and Cultural Office (TECO, 台北經濟文化辦事處) institutional framework, with the Taipei Economic and Cultural Office (or analogous Taiwan-side trade-office equivalent) operating in each of the eighteen target-country capitals.

The representative-office architecture imposes constraints on the bilateral-engagement architecture relative to a formal-diplomatic-relations framework. Representative offices cannot issue diplomatic visas, cannot conduct formal-treaty negotiations under the standard intergovernmental-treaty framework, and cannot engage in the full range of formal-diplomatic engagement that formal embassies conduct. The post-2016 New Southbound architecture has, however, operated around the representative-office constraint through a combination of quasi-treaty bilateral-investment-agreement and economic-cooperation-agreement architectures (concluded through representative-office channels and ratified through executive-branch implementation without formal-treaty parliamentary procedure), parliamentary-friendship-association exchanges (operating around the formal-diplomatic constraint through legislative-branch channels), and people-to-people exchanges (operating through the post-2016 four-pillar architecture).

5.1 Pillar 1 — Economic-and-Trade Cooperation

Pillar 1 (economic-and-trade cooperation, 經貿合作) of the New Southbound architecture covers the core bilateral trade-and-investment-architecture instruments. The pillar's principal instruments include: (i) bilateral investment agreements (BIAs), which provide formal investment-protection and treatment standards for Taiwanese investments in the target countries; (ii) industrial-cooperation platforms, which facilitate cross-border industrial integration and joint-venture development; (iii) free-trade-agreement negotiation, which would provide tariff-and-non-tariff trade-architecture benefits but which has not yielded post-2016 FTA conclusions with any New Southbound target country other than the pre-2016 ASTEP (Singapore, 2013) and ANZTEC (New Zealand, 2013) baselines; (iv) integrated value-chain architecture development, which has emerged as a post-2018 emphasis under the US-China trade-war reshoring dynamic.

The post-2016 BIA architecture has produced bilateral-investment-architecture updates. The 16 December 2018 Taiwan-India BIA signing [TBD-VERIFY] is the most consequential post-2016 BIA signing and provides the formal-investment-architecture foundation for the post-2018 Taiwan-India semiconductor-and-ICT cooperation surge. The post-2017 BIA renewals with the Philippines (2017 [TBD-VERIFY]) and Vietnam (2019 [TBD-VERIFY]) have updated the bilateral-investment-architecture relative to the pre-2008 baselines. The Taiwan-Indonesia bilateral-investment architecture has been updated through the post-2017 Updated Investment Agreement architecture [TBD-VERIFY: precise post-2016 Taiwan-Indonesia investment-agreement architecture and signing dates].

The industrial-cooperation platforms include: the Taiwan-Vietnam Industrial-Cooperation Forum (annual since 2017); the Taiwan-Indonesia Industrial-Cooperation Forum (annual since 2017); the Taiwan-India Industrial-Cooperation Forum (annual since 2018); and the Taiwan-Philippines Industrial-Cooperation Forum (annual since 2017). The forums provide cross-border industrial-coordination architecture, with annual MOU signings, joint-venture announcements, and industrial-standards harmonisation.

The integrated value-chain architecture has emerged as a post-2018 emphasis. The post-2018 US-China trade-war reshoring dynamic produced Taiwanese-manufacturing capacity migration from mainland China to ASEAN (predominantly Vietnam, Thailand, Indonesia, and Malaysia), with the New Southbound architecture providing the bilateral-policy framework supporting the migration. The post-2020 Resilient Supply Chain architecture has further intensified the integrated value-chain emphasis, with the post-2022 cross-Strait-decoupling logic and the post-2022 US-led Friend-Shoring framework providing both political-rhetorical and operational-architecture support for the migration trajectory.

5.2 Pillar 2 — Talent Exchange

Pillar 2 (talent exchange, 人才交流) of the New Southbound architecture covers the educational, professional, and people-to-people exchange instruments. The pillar's principal instruments include: (i) the Taiwan Scholarship Programme (台灣獎學金), which provides MOE-funded scholarships for undergraduate and graduate study at Taiwanese institutions; (ii) the Huayu Enrichment Scholarship (華語文獎學金), which provides Mandarin-language-study scholarships at Taiwanese institutions; (iii) the Taiwan Fellowship (台灣獎助金), which provides research-fellowship support for foreign academic researchers; (iv) the Taiwan-Connection Programme (台灣連結計畫), which maintains the alumni-network architecture across the New Southbound countries; (v) the International Higher-Education Cooperation Programme, which facilitates cross-border degree programmes and joint-research initiatives.

The Taiwan Scholarship Programme and the Huayu Enrichment Scholarship have expanded their New Southbound-disaggregated allocations across the 2016–2024 Tsai-era window. The total Taiwan Scholarship Programme awards across the eighteen New Southbound countries reached cumulative thousand-recipient levels by 2024 [TBD-VERIFY: precise cumulative Taiwan Scholarship Programme awards 2016–2024]. The Huayu Enrichment Scholarship has similarly expanded, with cumulative New Southbound recipients reaching cumulative thousand-recipient levels [TBD-VERIFY: precise cumulative Huayu Enrichment Scholarship awards 2016–2024]. The Taiwan-Connection Programme has built a substantial cross-country alumni-network architecture, providing soft-power-architecture foundations across the eighteen target countries.

The New Southbound student-population at Taiwanese higher-education institutions has expanded across the 2016–2024 Tsai-era window. By the 2018–2019 academic year, the total New Southbound student-population at Taiwanese institutions exceeded 50,000 students [TBD-VERIFY: precise New Southbound student-population figures 2018–2019]. The post-2020 COVID-19 disruption produced a student-population contraction across the 2020–2022 window, with subsequent post-2023 partial recovery. The 2024 New Southbound student-population was reported as exceeding 70,000 students [TBD-VERIFY: precise 2024 New Southbound student-population figures], representing approximately one-third of the total international-student population at Taiwanese institutions.

Pillar 3 (resource sharing, 資源共享) of the New Southbound architecture covers the medical, agricultural, ICT, and disaster-cooperation instruments. The pillar's flagship instrument is the One Country, One Centre (一國一中心, Yī Guó Yī Zhōngxīn) medical-cooperation architecture, launched in 2017 under MOHW coordination.

The One Country, One Centre architecture establishes Taiwan-led medical-cooperation hubs in seven first-tier New Southbound target countries: Indonesia (hub coordinated by Taipei Veterans General Hospital), the Philippines (hub coordinated by Chang Gung Memorial Hospital), Vietnam (hub coordinated by Taipei Medical University), Thailand (hub coordinated by Chung Shan Medical University), Malaysia (hub coordinated by China Medical University Hospital), India (hub coordinated by Taipei Medical University and National Cheng Kung University Hospital), and Myanmar (hub coordinated by Chang Gung Memorial Hospital) [TBD-VERIFY: precise hub-coordinator assignments for the seven One Country, One Centre architecture members]. The hubs conduct multiple-day medical-cooperation training programmes, equipment-transfer initiatives, joint-research projects, and Taiwanese medical-professional dispatch for clinical-cooperation engagement.

The post-March 2020 COVID-19 era re-articulated the medical-cooperation pillar through the mask diplomacy architecture. Taiwan's post-March 2020 donation of multiple-million medical masks to New Southbound target countries — operating in parallel with the post-April 2020 donations to US, Japan, and European partners — provided bilateral-engagement reinforcement during the pandemic-disruption window. The post-2021 vaccine-cooperation architecture, including the post-2021 Taiwan-Japan AstraZeneca vaccine-donation framework and the post-2022 medical-supply-chain-resilience architecture, has further consolidated the medical-cooperation pillar.

The agricultural-cooperation architecture under Pillar 3 includes technology-transfer initiatives (particularly tropical-agriculture, aquaculture, and tropical-fruit-processing cooperation), joint-venture agricultural-investment, and the Council of Agriculture's Taiwan-ICDF coordinated agricultural-cooperation projects across the New Southbound countries. The ICT-cooperation architecture under Pillar 3 includes ICT-infrastructure cooperation, digital-economy partnerships, and the post-2020 cybersecurity-cooperation framework.

5.4 Pillar 4 — Regional Linkages

Pillar 4 (regional linkages, 區域鏈結) of the New Southbound architecture covers the multilateral-platform participation and regional-value-chain integration instruments. The pillar's principal instruments include: (i) multilateral-platform participation, which has produced limited outcomes given the post-1971 One-China-framework constraint on Taiwan's multilateral-organisation participation; (ii) regional-value-chain integration, which has expanded under the post-2018 US-China trade-war reshoring dynamic; (iii) bilateral think-tank dialogue, which has produced policy-research cooperation across the New Southbound countries.

The multilateral-platform participation pillar has produced limited outcomes. Taiwan is not a member of ASEAN, ASEAN+3, the East Asia Summit, ASEAN Regional Forum, or any of the principal Asia-Pacific intergovernmental multilateral platforms (other than APEC, where Taiwan participates as Chinese Taipei under the post-1991 APEC accession architecture). The post-2016 New Southbound architecture has, however, expanded Taiwan's participation in Track 2 multilateral platforms (including the ASEAN-Taiwan Cooperation Framework working-level dialogues), professional-association multilateral platforms, and informal-multilateral platforms across the eighteen target countries.

The regional-value-chain integration pillar has expanded under the post-2018 US-China trade-war reshoring dynamic. The post-2018 Taiwanese-manufacturing capacity migration from mainland China to ASEAN — particularly to Vietnam, Thailand, Indonesia, and Malaysia — has re-architected the regional value-chain architecture. By 2024, the post-2018 ASEAN-located Taiwanese-manufacturing capacity (electronics, ICT, automotive, textiles) had reached substantial levels, with the Vietnam Taiwanese-investment surge (post-2018 cumulative additional investment exceeding US$10 billion) being the most consequential migration pattern.

The bilateral think-tank dialogue architecture includes: the Taiwan-ASEAN Studies Centre (台灣亞洲研究中心) at Tamkang University; the Centre for Southeast Asian Studies at National Chi Nan University; the Indo-Pacific Studies Centre at Academia Sinica; the Prospect Foundation (遠景基金會) Taiwan-foreign-policy track-2 dialogue; and the Taiwan-India Centre at National Tsing Hua University and National Sun Yat-sen University. The think-tank architecture has produced policy-research cooperation with counterpart think-tanks across the eighteen target countries, including the Institute of Southeast Asian Studies – Yusof Ishak Institute (ISEAS, Singapore), the Lowy Institute (Sydney), the Observer Research Foundation (New Delhi), and the Center for Strategic and International Studies Indonesia (Jakarta).

6. The 2016–2019 First-Term Implementation — Trade and Investment

6.1 The 2016–2019 Bilateral-Trade-Flow Trajectory

Across the 2016–2019 first-term implementation window, the Taiwan-New-Southbound bilateral-trade-flow trajectory showed substantial year-over-year growth. The MOEA Bureau of Foreign Trade trade-flow statistics indicate that the total Taiwan-New-Southbound bilateral-trade-flow expanded from approximately US$96 billion in 2015 to approximately US$117 billion in 2018, representing approximately 22 per cent cumulative growth across the three-year post-launch window [TBD-VERIFY: precise 2015–2018 Taiwan-New-Southbound bilateral-trade-flow figures]. The trade-flow expansion was broadly distributed across the eighteen target countries, with the largest absolute increases occurring in trade with Vietnam (electronics, machinery), India (ICT, machinery), and Indonesia (petrochemicals, electronics).

The post-2018 US-China trade-war launch (the first-tranche Section 301 tariffs implemented 6 July 2018 by the Trump administration) produced a acceleration in the Taiwan-New-Southbound bilateral-trade-flow growth across the 2018–2019 window. The Taiwan-Vietnam bilateral-trade-flow, in particular, expanded substantially as Taiwanese manufacturers re-routed their PRC-located production to Vietnam-located facilities. The 2019 Taiwan-New-Southbound bilateral-trade-flow reached approximately US$131 billion, representing approximately 12 per cent year-over-year growth from 2018 [TBD-VERIFY: precise 2019 Taiwan-New-Southbound bilateral-trade-flow figures].

The composition of the Taiwan-New-Southbound trade-flow has been concentrated in: (i) intermediate-goods exports from Taiwan to New Southbound manufacturing hubs (particularly electronics, ICT components, and machinery components); (ii) finished-goods exports from New Southbound manufacturing hubs to Taiwan and global destinations; (iii) energy and raw-materials imports from New Southbound countries to Taiwan (particularly Indonesian petrochemicals and coal, Australian iron ore and coal, Malaysian palm oil, and Vietnamese agricultural products). The trade-flow composition has reflected the integrated regional-value-chain architecture rather than a simple Taiwan-export / New-Southbound-import binary.

6.2 The 2016–2019 Outbound-Investment Flow Trajectory

The post-2016 Taiwanese outbound-investment flow to New Southbound countries has expanded across the 2016–2019 first-term implementation window. MOEA Investment Commission outbound-investment statistics indicate that Taiwanese annual outbound-investment flow to New Southbound countries expanded from approximately US$3.8 billion in 2015 to approximately US$5.0 billion in 2018 [TBD-VERIFY: precise 2015–2018 annual Taiwanese-New-Southbound outbound-investment-flow figures]. The cumulative Taiwanese-New-Southbound investment across the 2016–2019 four-year window exceeded US$20 billion in incremental flow.

The post-2018 US-China trade-war reshoring dynamic produced a acceleration in Taiwanese outbound-investment to ASEAN. The 2019 Taiwanese outbound-investment to ASEAN reached approximately US$6 billion [TBD-VERIFY: precise 2019 Taiwanese-ASEAN outbound-investment-flow figures], representing a increase from the 2017 baseline. The largest absolute outbound-investment-flow expansions occurred in Vietnam (textiles, electronics, ICT manufacturing), Indonesia (petrochemicals, electronics), Thailand (automotive components, electronics), and Malaysia (electronics, ICT).

The post-2018 Taiwan-India semiconductor-and-ICT cooperation has emerged as a post-2018 outbound-investment trajectory. The post-2018 Foxconn investment in India (manufacturing hub in Sriperumbudur, Tamil Nadu — substantially expanded post-2018 with the iPhone-assembly capacity buildup) [TBD-VERIFY: precise post-2018 Foxconn India investment figures] represents the most consequential single post-2018 outbound-investment commitment. The subsequent post-2022 Foxconn-Vedanta semiconductor-fab proposal (subsequently dissolved July 2023) and the post-2024 PSMC-Tata semiconductor-fab proposal have further intensified the Taiwan-India semiconductor-cooperation trajectory.

6.3 The Bilateral Investment Agreement Architecture

The post-2016 New Southbound bilateral-investment-agreement architecture has produced updates to the pre-2016 bilateral-investment-architecture baselines. The 16 December 2018 Taiwan-India Bilateral Investment Agreement [TBD-VERIFY: precise 2018 Taiwan-India BIA signing date — the post-2018 BIA is widely reported as supplanting the earlier 2002 Taiwan-India BIA and providing updated investment-protection-architecture] is the most consequential post-2016 BIA signing. The Taiwan-India BIA provides formal investment-protection standards (national treatment, most-favoured-nation treatment, fair-and-equitable treatment, full-protection-and-security treatment), expropriation-protection standards, and dispute-resolution-architecture provisions.

The post-2017 BIA renewals with the Philippines (2017 [TBD-VERIFY: precise 2017 Taiwan-Philippines BIA renewal date]) and Vietnam (2019 [TBD-VERIFY: precise 2019 Taiwan-Vietnam BIA renewal date]) have updated the bilateral-investment-architecture relative to the pre-2008 baselines. The Taiwan-Indonesia bilateral-investment architecture has been updated through the post-2017 Updated Investment Agreement architecture and the subsequent post-2020 implementation regulations [TBD-VERIFY].

6.4 The 2018–2019 One Country, One Centre Medical-Cooperation Implementation Record

The One Country, One Centre medical-cooperation architecture, launched in 2017 under MOHW coordination, produced 2018–2019 implementation outcomes. The seven first-tier medical-cooperation hubs (Indonesia, Philippines, Vietnam, Thailand, Malaysia, India, Myanmar) conducted multiple-thousand-trainee-level training programmes across 2018–2019, with cumulative training-engagement reaching several-thousand-trainee levels by the end of 2019 [TBD-VERIFY: precise cumulative One Country, One Centre training-engagement figures 2017–2019]. The MOHW provided funding-architecture support, with annual MOHW One Country, One Centre funding reaching tens-of-millions-NTD levels by 2019 [TBD-VERIFY: precise annual MOHW One Country, One Centre funding figures 2017–2019].

7. The 2016–2019 First-Term Implementation — Tourism and Education

7.1 The Post-2016 Visa-Easing Architecture

The post-2016 Tsai administration expanded the visa-easing architecture for New Southbound countries as a principal tourism-flow-architecture instrument. The first wave of visa-easing was implemented in August 2016, with visa-waiver implementation for Thai and Bruneian nationals on a multi-day trial basis [TBD-VERIFY: precise August 2016 Thailand and Brunei visa-waiver implementation dates and duration provisions]. The August 2016 visa-waiver implementation was the first post-inaugural New Southbound implementation move, signalling the administration's tourism-flow-architecture priority.

The second wave of visa-easing was implemented in November 2017, with the Philippines added to the visa-waiver architecture under multi-day trial provisions [TBD-VERIFY: precise November 2017 Philippines visa-waiver implementation date]. The third wave of visa-easing was the post-2018 Indonesia e-Visa architecture, with Indonesian travellers to Taiwan gaining access to streamlined online-visa-application architecture across the 2018–2020 implementation window [TBD-VERIFY: precise post-2018 Indonesia e-Visa architecture launch].

The visa-easing architecture's effects on New Southbound tourism-flow were substantial. The Thai tourist-arrival trajectory expanded from approximately 125,000 in 2015 to approximately 320,000 in 2018, representing approximately 156 per cent cumulative growth across the three-year post-visa-waiver window [TBD-VERIFY: precise 2015–2018 Thai tourist-arrival figures]. The Filipino tourist-arrival trajectory expanded substantially post-November 2017 visa-waiver, with the 2018 Filipino tourist-arrival reaching approximately 420,000 [TBD-VERIFY: precise 2018 Filipino tourist-arrival figures].

7.2 The 2016–2019 New Southbound Tourist-Arrival Trajectory

The aggregate New Southbound tourist-arrival trajectory across 2015–2019 showed substantial growth. The total New Southbound tourist-arrival expanded from approximately 1.6 million in 2015 to approximately 2.6 million in 2019, representing approximately 63 per cent cumulative growth across the four-year window [TBD-VERIFY: precise 2015–2019 New Southbound tourist-arrival figures]. The 2019 New Southbound tourist-arrival represented approximately 22 per cent of Taiwan's total inbound-tourist-arrival of approximately 11.86 million in 2019 [TBD-VERIFY: precise 2019 Taiwan total inbound-tourist-arrival figures and New Southbound share].

The growth was concentrated in arrivals from Vietnam (post-2017 surge driven by the rapid growth of Vietnamese-middle-class outbound tourism), Thailand (post-August 2016 visa-waiver effect), the Philippines (post-November 2017 visa-waiver effect), Indonesia (driven by the Indonesian-middle-class outbound-tourism growth), and India (substantial post-2018 growth from a smaller baseline). The Malaysia-and-Singapore tourist-arrival baseline, already substantial pre-2016 given the absence of pre-existing visa requirements, continued to grow modestly across the 2016–2019 window.

The post-2016 Tsai administration's tourism-flow architecture was substantially driven by both the visa-easing architecture and the parallel post-2017 cross-Strait tourist-arrival contraction. The post-2016 PRC restriction on group-tourism to Taiwan — implemented from 2017 onward and intensified post-2019 — produced a cross-Strait tourism-flow contraction, with the PRC tourist-arrival to Taiwan declining from approximately 4.18 million in 2015 to approximately 2.71 million in 2019 [TBD-VERIFY: precise 2015–2019 PRC tourist-arrival to Taiwan figures]. The post-2017 New Southbound tourist-arrival growth substantially compensated for the cross-Strait tourism-flow contraction, with the New Southbound architecture providing the tourism-architecture diversification that the post-2017 cross-Strait tourism-flow contraction required.

7.3 The 2016–2019 New Southbound Education-Exchange Implementation Record

The post-2016 New Southbound education-exchange architecture has produced 2016–2019 implementation outcomes. The Taiwan Scholarship Programme awards to New Southbound students expanded from approximately 250 awards in the 2015–2016 academic year to approximately 450 awards in the 2018–2019 academic year [TBD-VERIFY: precise Taiwan Scholarship Programme New Southbound award figures 2015–2019]. The Huayu Enrichment Scholarship awards to New Southbound students expanded substantially across the same window. The Taiwan-Connection Programme — the post-2016 alumni-network architecture — built a multi-country alumni-network architecture by the end of 2019.

The aggregate New Southbound student-population at Taiwanese higher-education institutions expanded substantially across the 2015–2019 window. The total New Southbound student-population at Taiwanese institutions expanded from approximately 28,000 in the 2015–2016 academic year to approximately 51,000 in the 2018–2019 academic year, representing approximately 82 per cent cumulative growth across the four-year window [TBD-VERIFY: precise New Southbound student-population figures 2015–2019]. The 2018–2019 New Southbound student-population represented approximately 41 per cent of Taiwan's total international-student population of approximately 126,000 in the 2018–2019 academic year [TBD-VERIFY: precise 2018–2019 Taiwan total international-student population figures and New Southbound share].

The growth was concentrated in students from Vietnam (cumulative growth driven by the post-2017 expansion of Vietnamese-middle-class outbound-education flows), Indonesia (substantial post-2017 growth), the Philippines (substantial post-2017 growth), Malaysia (substantial baseline expansion given the pre-existing Malaysia-Taiwan education-exchange architecture), and India (substantial post-2018 growth from a smaller baseline). The post-2016 Tsai administration's New Southbound education-architecture has subsequently been criticised by both KMT-aligned media and some Taiwanese higher-education institutions for the post-2017 emergence of student-broker malpractice in some New Southbound recruitment channels — particularly in some Vietnam-recruitment and Indonesia-recruitment programmes — with subsequent post-2019 MOE regulatory tightening [TBD-VERIFY: precise post-2017 student-broker malpractice incidents and MOE regulatory responses].

7.4 The 2017–2019 Taiwan-Connection Alumni-Network Architecture

The Taiwan-Connection Programme (台灣連結計畫), launched in 2017 under MOFA and MOE coordination, has built a multi-country alumni-network architecture. The programme maintains country-by-country alumni associations across the eighteen New Southbound countries, with multi-thousand-member alumni-association registrations by the end of 2019 [TBD-VERIFY: precise 2019 Taiwan-Connection Programme alumni-association membership figures].

The programme conducts annual country-by-country alumni events (typically in conjunction with the Taiwan representative-office annual events), provides career-network and business-network architecture across the alumni cohort, and operates as a soft-power-architecture instrument across the eighteen target countries. The programme's soft-power outcomes have been particularly evident in Vietnam, Indonesia, the Philippines, Malaysia, Thailand, and India, where the alumni networks have produced bilateral-engagement-architecture reinforcement across both economic-and-political domains.

8. The 2020 COVID-19 Disruption and the 2020–2023 Partial Recovery

8.1 The Post-March 2020 International-Travel Collapse and the New Southbound Tourism-Flow Contraction

The post-March 2020 international-travel collapse, consequent to the global COVID-19 pandemic, disrupted the New Southbound tourism-flow architecture. Taiwan's post-19 March 2020 border-restriction implementation — effectively closing the Taiwanese border to non-resident foreign nationals from 19 March 2020 onward — produced a near-total collapse in international-tourist arrivals across the post-March 2020 window.

The 2020 Taiwan total inbound-tourist arrival collapsed to approximately 1.38 million (predominantly January–February 2020 pre-restriction arrivals), representing approximately 88 per cent contraction from the 2019 baseline of 11.86 million [TBD-VERIFY: precise 2020 Taiwan total inbound-tourist-arrival figures]. The 2021 Taiwan total inbound-tourist arrival reached approximately 140,000, representing further contraction. The 2022 Taiwan total inbound-tourist arrival reached approximately 900,000, reflecting the post-13 October 2022 border re-opening [TBD-VERIFY: precise 2021–2022 Taiwan total inbound-tourist-arrival figures and border-re-opening date].

The New Southbound tourist-arrival contraction was correspondingly substantial. The 2020 New Southbound tourist-arrival collapsed to approximately 300,000, representing approximately 88 per cent contraction from the 2019 baseline of 2.6 million [TBD-VERIFY: precise 2020 New Southbound tourist-arrival figures]. The 2021 New Southbound tourist-arrival reached approximately 30,000. The 2022 New Southbound tourist-arrival reached approximately 200,000.

8.2 The Post-March 2020 Mask Diplomacy Architecture

The post-March 2020 medical-cooperation pillar was re-articulated through the mask diplomacy (口罩外交, Kǒuzhào Wàijiāo) architecture. Taiwan's post-March 2020 donation of multiple-million medical masks to New Southbound target countries — operating in parallel with the post-April 2020 donations to US, Japan, and European partners — provided bilateral-engagement reinforcement during the pandemic-disruption window.

The Tsai administration's 1 April 2020 announcement of the initial mask-donation programme committed approximately 10 million masks to international partners, with subsequent donation expansions across the April–August 2020 window [TBD-VERIFY: precise post-March 2020 Taiwan international mask-donation total figures and country-by-country breakdown]. The New Southbound countries — particularly Vietnam, Indonesia, the Philippines, Thailand, Malaysia, and India — received mask-donation shipments across the 2020 window. The mask diplomacy architecture provided soft-power-and-medical-cooperation architecture reinforcement during the pandemic-disruption window, with continuing bilateral-engagement-architecture benefits across the post-2020 window.

8.3 The 2021–2022 Vaccine-Cooperation Architecture and the Medical-Supply-Chain Resilience Framework

The post-2021 vaccine-cooperation architecture extended the medical-cooperation pillar across the 2021–2022 window. Taiwan's post-June 2021 receipt of vaccine donations from Japan (the post-4 June 2021 AstraZeneca donation of 1.24 million doses) and the US (the post-19 June 2021 Moderna donation of 2.5 million doses) [TBD-VERIFY: precise post-June 2021 vaccine-donation figures and dates] re-articulated the medical-cooperation architecture, with Taiwan subsequently producing the post-2021 domestic Medigen vaccine and the post-2022 Taiwan-led vaccine-and-medical-supply-cooperation architecture.

The post-2022 Medical-Supply-Chain Resilience Framework — an evolution of the One Country, One Centre architecture — emphasised the cross-border medical-supply-chain integration architecture across the New Southbound countries, with supply-chain-integration initiatives across pharmaceutical manufacturing, medical-device manufacturing, and emergency-medical-supply stockpiling.

8.4 The 2020–2023 Trade-and-Investment Flow Continuation

In contrast to the tourism-flow contraction, the Taiwan-New-Southbound bilateral-trade-flow continued to grow across the 2020–2023 COVID-19 era. The 2020 Taiwan-New-Southbound bilateral-trade-flow reached approximately US$118 billion, representing a modest contraction from the 2019 baseline of approximately US$131 billion but smaller contraction than the tourism-flow contraction [TBD-VERIFY: precise 2020 Taiwan-New-Southbound bilateral-trade-flow figures]. The 2021 Taiwan-New-Southbound bilateral-trade-flow expanded to approximately US$150 billion, reflecting both the post-2020 global trade-recovery and the post-2020 supply-chain-architecture re-emphasis on ASEAN production capacity [TBD-VERIFY: precise 2021 Taiwan-New-Southbound bilateral-trade-flow figures]. The 2022 Taiwan-New-Southbound bilateral-trade-flow reached approximately US$181 billion, with the 2023 figure reaching approximately US$170 billion [TBD-VERIFY: precise 2022 and 2023 Taiwan-New-Southbound bilateral-trade-flow figures].

The Taiwanese outbound-investment flow to New Southbound countries also continued at substantial levels across the 2020–2023 window. The 2020 Taiwanese-New-Southbound outbound-investment flow reached approximately US$5 billion, and the 2021–2022 outbound-investment flow exceeded US$6 billion annually [TBD-VERIFY: precise 2020–2022 Taiwanese-New-Southbound outbound-investment-flow figures]. The post-2020 outbound-investment flow was driven substantially by the continuing US-China trade-war reshoring dynamic, the post-2020 Resilient Supply Chain architecture, and the post-2022 Taiwan-India semiconductor-cooperation surge.

9. The 23 September 2021 CPTPP Application and the Post-2021 Multilateral-Trade-Architecture Trajectory

9.1 The CPTPP Genealogy — From the 2008 TPP to the 8 March 2018 Santiago Signing

The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) emerged from the pre-2017 Trans-Pacific Partnership (TPP) architecture. The TPP, originating from the 2005 Trans-Pacific Strategic Economic Partnership Agreement among Brunei, Chile, New Zealand, and Singapore, was expanded across the post-2008 Obama-administration Pivot to Asia framework into a twelve-member agreement signed Auckland 4 February 2016. The original TPP twelve members included Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, the United States, and Vietnam.

The 23 January 2017 Trump-administration executive order withdrawing the United States from the TPP disrupted the original-TPP architecture. The remaining eleven members subsequently re-negotiated the agreement under the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) framing, signed Santiago 8 March 2018 by the eleven post-US-withdrawal members. The CPTPP largely preserved the original TPP provisions while suspending approximately twenty TPP provisions that had been particularly US-driven (including intellectual-property and investor-state-dispute-settlement provisions). The CPTPP entered into force on 30 December 2018 for the first six ratifying members (Australia, Canada, Japan, Mexico, New Zealand, Singapore); the remaining five members ratified across the post-2018 window.

9.2 The 16 September 2021 PRC Application and the 23 September 2021 Taiwan Application

The post-2021 CPTPP-application architecture was shaped by the parallel PRC-and-Taiwan applications submitted within one week of each other. The PRC formally submitted its CPTPP application on 16 September 2021, with the application letter delivered through the New Zealand depositary (New Zealand serves as the formal depositary for the CPTPP agreement). The PRC application was significant given the magnitude of the PRC economy and the substantial gap between PRC current trade-architecture practice and the CPTPP-required standards on state-owned enterprises, intellectual-property protection, labour standards, and digital-trade standards.

Taiwan formally submitted its CPTPP application on 23 September 2021, with the application letter delivered through the New Zealand depositary one week after the PRC application. The Taiwan application was formally submitted in the name of Separate Customs Territory of Taiwan, Penghu, Kinmen and Matsu (the WTO accession nomenclature). The post-23 September 2021 Taiwan application has been managed by the Office of Trade Negotiations under Chief Negotiator John Deng (through 2020) and subsequently Yang Jen-ni (post-2020) [TBD-VERIFY: precise OTN Chief Negotiator chronology and the post-2021 Taiwan CPTPP-application-management chronology].

9.3 The Post-2021 CPTPP Commission Deliberation Architecture

The post-September 2021 PRC-and-Taiwan parallel-application architecture has produced a continuing CPTPP-Commission-level deliberation question. The CPTPP Commission, comprising trade ministers from the eleven (subsequently twelve, post-2024 UK accession) member states, operates under a consensus-decision-architecture for accession applications. New member accession requires both working-party review (a country-by-country assessment of the applicant's compliance with CPTPP-required standards) and unanimous Commission approval.

The post-2021 PRC application has been complicated by the PRC's current trade-architecture distance from CPTPP-required standards, with the post-2021 working-party deliberations producing limited progress through 2026 [TBD-VERIFY: precise post-2021 PRC CPTPP application working-party status and developments]. The post-2021 Taiwan application has been similarly complicated, with the post-2021 working-party deliberations producing limited progress despite the Taiwan-side readiness to comply with CPTPP-required standards. The parallel-application dynamic has been recognised as producing political-architecture complications for the CPTPP-Commission decision-architecture, with substantial Commission-member uncertainty about how to manage the parallel PRC-Taiwan application sequence.

9.4 The 2 July 2023 UK Accession as Precedent

The first post-2018 CPTPP accession — the United Kingdom's accession, with the accession agreement signed 16 July 2023 and entered into force 15 December 2024 [TBD-VERIFY: precise UK CPTPP accession signing and entry-into-force dates] — has provided precedent for the post-2021 PRC-and-Taiwan application architecture. The UK accession was approved through the standard CPTPP Commission working-party architecture, with the UK working-party established post-2021 and completing its work across the 2021–2023 window. The UK accession is significant as the first non-Asia-Pacific accession (under the CPTPP's geographic flexibility provisions) and as the first accession-precedent for the post-2021 PRC-and-Taiwan applications.

The UK-accession-precedent provides limited guidance for the PRC-and-Taiwan application sequence, however. The UK application was politically uncomplicated (no Commission-member geopolitical objections), whereas the PRC-and-Taiwan parallel-application sequence is politically complicated by the cross-Strait architecture, the post-2021 PRC objection to any Taiwan accession ahead of PRC accession, and the substantial Commission-member reluctance to engage with the cross-Strait-politically-complicated application sequence.

9.5 The Six CPTPP-Member New Southbound Countries

Six of the eighteen New Southbound target countries are CPTPP members: Singapore, Malaysia, Vietnam, Brunei (the four ASEAN CPTPP members), and Australia and New Zealand. A successful Taiwan accession to the CPTPP would re-architect the bilateral-trade-architecture with these six countries, providing tariff-and-non-tariff trade-architecture benefits beyond the current bilateral-architecture baselines (which include the ASTEP with Singapore from 2013 and the ANZTEC with New Zealand from 2013 but no other formal-FTA architecture with the remaining four CPTPP-member countries).

The trade-architecture benefits would be most consequential for Taiwan-Malaysia, Taiwan-Vietnam, and Taiwan-Australia bilateral-trade-architecture, where Taiwan currently faces standard most-favoured-nation tariff treatment under WTO architecture. The trade-architecture benefits would also extend to the CPTPP-required digital-trade, government-procurement, and investment-protection provisions, providing bilateral-architecture upgrades beyond the current bilateral-architecture baselines.

10. The Post-2020 Tsai Second-Term Re-Articulation — Resilient Supply Chain and the Cross-Strait-Decoupling Logic

10.1 The 20 May 2020 Second-Term Inaugural and the Post-2020 Strategic-Architecture Re-Emphasis

President Tsai Ing-wen's 20 May 2020 second-term inaugural address articulated a economic-strategic-architecture re-emphasis. The post-2020 inaugural emphasised "Six Core Strategic Industries" (六大核心戰略產業, Liù Dà Héxīn Zhànlüè Chǎnyè): information and digital industries; cybersecurity industries; biotechnology and medical industries; defence industries; renewable-energy industries; and strategic-stockpiling industries [TBD-VERIFY: precise post-2020 Six Core Strategic Industries taxonomy]. The post-2020 inaugural framing re-articulated the New Southbound architecture as a component of the broader strategic-industry architecture, with the post-2020 cross-Strait-decoupling logic providing the architectural foundation for the bilateral-engagement architecture.

The post-2020 Resilient Supply Chain (供應鏈韌性, Gōngyìngliàn Rènxìng) framing emerged as the principal post-2020 architectural emphasis. The Resilient Supply Chain framing emphasised the cross-Strait-decoupling logic of the bilateral-engagement architecture and the cross-reference with the post-2020 US-led Friend-Shoring and De-Risking frameworks. The post-2020 New Southbound architecture was re-articulated under the Resilient Supply Chain framing, with the post-2020 bilateral-engagement architecture emphasising semiconductor-and-electronics-supply-chain integration with the New Southbound countries (particularly Vietnam, Malaysia, Thailand, India, and Indonesia).

10.2 The Post-2022 IPEF Taiwan-Exclusion Question

The post-2022 Indo-Pacific Economic Framework (IPEF) Taiwan-exclusion question was a setback for the post-2020 New Southbound architecture. The Biden administration's 23 May 2022 IPEF launch in Tokyo included thirteen Indo-Pacific founding members (Australia, Brunei, Fiji [added subsequently], India, Indonesia, Japan, South Korea, Malaysia, New Zealand, Philippines, Singapore, Thailand, Vietnam, and the United States), but pointedly excluded Taiwan from the founding-member architecture. The IPEF-exclusion was complicated by the parallel 22 May 2022 US-Taiwan Initiative on 21st Century Trade launch announcement, which provided a bilateral-architecture parallel to IPEF but at a smaller scale than the multilateral IPEF architecture.

The IPEF-exclusion was widely criticised in Taiwan, including both DPP-aligned and KMT-aligned commentary. The DPP-aligned commentary emphasised the setback to Taiwan's multilateral-trade-architecture engagement and the consequent intensified necessity of the New Southbound bilateral-engagement architecture. The KMT-aligned commentary emphasised the post-2016 DPP-administration failure to maintain Taiwan's multilateral-engagement architecture, with the cross-Strait-engagement architecture having been eroded under the post-2016 partial-ECFA-maintenance equilibrium.

10.3 The 2022–2023 US-Taiwan 21st Century Trade Initiative Parallel-Architecture

The 22 May 2022 US-Taiwan Initiative on 21st Century Trade launch provided a bilateral-architecture parallel to IPEF. The initiative's first-tranche agreement was signed 1 June 2023 in Washington by USTR Katherine Tai and Taiwan Office of Trade Negotiations Chief Negotiator Yang Jen-ni [TBD-VERIFY: precise 1 June 2023 first-tranche signing date and signatories]. The first-tranche agreement covered customs administration, regulatory practices, services-domestic-regulation, anticorruption, and small-and-medium-enterprise architecture provisions. The second-tranche agreement, covering labour, environment, agriculture, digital trade, standards, state-owned enterprises, and non-market policies and practices, was negotiated across the post-2023 window with substantial subsequent post-2024 negotiation activity.

The US-Taiwan Initiative on 21st Century Trade architecture provided bilateral-architecture reinforcement to the post-2020 New Southbound architecture, particularly through the cross-reference between US-Taiwan trade-architecture standards and the parallel CPTPP-required standards. The initiative's provisions broadly aligned with CPTPP-required standards, providing the trade-architecture standards-alignment that the post-2021 Taiwan CPTPP application required.

10.4 The Post-2022 Semiconductor-Supply-Chain Integration with the New Southbound Countries

The post-2022 semiconductor-supply-chain integration architecture has emerged as a post-2020 Resilient Supply Chain architecture emphasis. The post-2022 Taiwan-India semiconductor-cooperation has intensified through the post-2022 Foxconn-Vedanta semiconductor-fab proposal (announced February 2022, subsequently dissolved July 2023) and the post-2024 PSMC-Tata semiconductor-fab proposal (announced February 2024 for a US$11 billion fab in Dholera, Gujarat) [TBD-VERIFY: precise post-2022 Foxconn-Vedanta and post-2024 PSMC-Tata fab announcement details]. The post-2022 Taiwan-Vietnam semiconductor-cooperation has also expanded, with Foxconn and ASE-Group making substantial post-2022 capacity-expansion announcements in Vietnam.

The post-2022 Taiwan-Indonesia semiconductor-cooperation, the post-2022 Taiwan-Malaysia semiconductor-cooperation (particularly packaging-and-testing capacity), and the post-2022 Taiwan-Thailand semiconductor-cooperation have all expanded substantially. The semiconductor-supply-chain integration architecture represents a evolution of the New Southbound architecture beyond the initial 2016–2019 manufacturing-cooperation emphasis toward the post-2020 semiconductor-and-electronics-supply-chain integration emphasis.

11. The Post-20 May 2024 Lai-Inaugural Continuation — The Vice Premier Cheng Li-chiun Office of Trade Negotiations Re-Architecture

11.1 The 20 May 2024 Lai Inaugural and the Continuing-New-Southbound-Emphasis

President Lai Ching-te's (賴清德) 20 May 2024 inaugural address articulated a continuing-New-Southbound-emphasis. The inaugural address explicitly referenced the New Southbound Policy as a continuing-architecture priority of the post-2024 Lai administration, with the bilateral-engagement architecture's continuation across the post-2024 window reinforcing the post-2020 Resilient Supply Chain architectural framing.

The Lai inaugural framing was continuous with the post-2020 Tsai second-term framing rather than constituting a policy-reset. The Lai administration's broader strategic-architecture continuity — consistent with the post-2020 Tsai second-term emphasis on the Six Core Strategic Industries, the cross-Strait-decoupling logic, the silicon-shield strategic-architecture, and the post-2022 US-led Friend-Shoring coordination — provided the architectural foundation within which the post-2024 New Southbound continuation operates.

11.2 The Vice Premier Cheng Li-chiun Appointment and the OTN Re-Structuring

The post-20 May 2024 Lai administration appointed Cheng Li-chiun (鄭麗君, 1969–) — previously Minister of Culture under the Tsai administration 2016–2020 and post-2020 DPP central-party-level figure — as Vice Premier under Premier Cho Jung-tai (卓榮泰, premier from 20 May 2024). The Cheng Li-chiun Vice Premier appointment was significant: as a senior DPP figure with strategic-architecture experience, Cheng provided the cross-portfolio coordination capacity that the post-2024 New Southbound architecture's continuing implementation required.

The OTN was re-structured under the post-2024 Lai administration. The post-2024 OTN Chief Negotiator Yang Jen-ni (楊珍妮) — previously Vice Minister of Economic Affairs under the post-2020 Tsai administration and post-2020 OTN Chief Negotiator — has continued in her OTN Chief Negotiator role under the post-2024 Lai administration, providing continuity across the Tsai-Lai transition. The post-2024 OTN has been re-architected with expanded portfolio coverage of: (i) post-Trump-2 reciprocal-tariff negotiation; (ii) continuing CPTPP-application management; (iii) post-2024 New Southbound architecture re-articulation; (iv) continuing US-Taiwan Initiative on 21st Century Trade second-tranche negotiation.

11.3 The Post-2024 New Southbound Policy Re-Articulation Plan

The post-2024 Lai administration has released a New Southbound Policy Re-Articulation Plan (新南向政策再articular計畫) across the post-20 May 2024 window [TBD-VERIFY: precise post-2024 Re-Articulation Plan release date and full title]. The post-2024 plan preserves the eighteen-target-country geography and the four-pillar architecture while introducing post-2024 emphases on:

(i) Semiconductor-supply-chain integration — intensification of the post-2022 semiconductor-cooperation architecture, with the post-2024 emphasis on Taiwan-India, Taiwan-Vietnam, and Taiwan-Indonesia semiconductor-cooperation;

(ii) Digital-economy cooperation — emphasis on cross-border digital-economy cooperation, including digital-trade architecture, cybersecurity-cooperation architecture, and digital-finance cooperation;

(iii) Cross-Strait-decoupling logic continuation — continuation of the post-2020 Resilient Supply Chain architectural framing, with the post-2024 cross-Strait architecture's continuing-pressure dynamics providing architectural reinforcement;

(iv) Multilateral-engagement intensification — intensification of multilateral-engagement architecture, including the continuing CPTPP-application management, the post-2024 US-Taiwan Initiative on 21st Century Trade second-tranche advancement, and the post-2024 Indo-Pacific multilateral-engagement architecture.

11.4 The Post-2024 Country-by-Country Bilateral-Engagement Re-Emphasis

The post-2024 New Southbound architecture has re-emphasised certain country-by-country bilateral-engagement priorities. The Taiwan-India bilateral-engagement architecture has been intensified, with the post-2024 Lai administration emphasising the Taiwan-India semiconductor-cooperation, ICT-cooperation, and skilled-labour-mobility architecture (including the December 2024 Taiwan-India Mobility Agreement signing for Indian skilled-labour mobility to Taiwan [TBD-VERIFY: precise December 2024 Taiwan-India Mobility Agreement signing date]).

The Taiwan-Vietnam bilateral-engagement architecture has continued at substantial post-2024 levels, with the post-2024 Taiwan-Vietnam semiconductor-cooperation, electronics-supply-chain integration, and labour-mobility architecture (Vietnam continues to be Taiwan's largest source of migrant labour, with post-2024 migrant-labour-cooperation arrangements continuing to expand). The Taiwan-Indonesia, Taiwan-Philippines, and Taiwan-Thailand bilateral-engagement architectures have similarly continued at substantial post-2024 levels.

The post-2024 Taiwan-Australia bilateral-engagement architecture has been re-articulated under the post-2024 AUKUS-and-Indo-Pacific architecture dynamic, with the post-2024 Taiwan-Australia critical-mineral-cooperation, agricultural-cooperation, and indigenous-cooperation architecture providing bilateral-engagement reinforcement.

12. The Post-April 2025 Trump-2 Reciprocal-Tariff Architecture and the 2025–2026 Recalibration

12.1 The 2 April 2025 Liberation Day Reciprocal-Tariff Announcement

The 2 April 2025 Trump-2 administration Liberation Day reciprocal-tariff announcement transformed the post-2025 trade-architecture environment within which the New Southbound architecture operates. The 2 April 2025 announcement, delivered by President Trump at the White House Rose Garden, introduced reciprocal-tariff rates applied to substantially all US trading partners under the International Emergency Economic Powers Act (IEEPA) framework.

The 2 April 2025 announcement included a 32 per cent reciprocal-tariff rate applied to Taiwan, calculated under the Trump-2 administration's reciprocal-tariff formula that took into account Taiwan's substantial bilateral-trade-surplus with the United States [TBD-VERIFY: precise April 2025 Taiwan reciprocal-tariff rate — 32 per cent is widely reported but precise figure varies across sources]. The Taiwan reciprocal-tariff rate was higher than the rates applied to several Asia-Pacific competitors, producing Taiwan-export-architecture competitive-disadvantage concerns.

The post-9 April 2025 reciprocal-tariff 90-day pause — announced by President Trump on 9 April 2025, with the reciprocal-tariff rates reduced to a 10 per cent baseline for non-PRC trading partners across the 90-day window — provided a trade-architecture relief and an opening for bilateral-tariff-negotiation across the April–July 2025 window [TBD-VERIFY: precise post-9 April 2025 reciprocal-tariff 90-day pause architecture and subsequent negotiation-window provisions].

12.2 The Post-April 2025 OTN Tariff-Negotiation Response

The post-April 2025 OTN tariff-negotiation response under Chief Negotiator Yang Jen-ni and Vice Premier Cheng Li-chiun has re-engaged with the Trump-2 administration across the post-April 2025 window. The Taiwan-US tariff-negotiation architecture has involved multiple OTN-USTR meetings across the April–November 2025 window, with the Taiwan-side offers including substantial US-investment commitments (particularly TSMC's post-2025 expansion of its Arizona fab investment from US$65 billion to US$165 billion, announced March 2025), substantial US-agricultural-and-energy import commitments, and Taiwan-side regulatory-reform commitments [TBD-VERIFY: precise post-April 2025 OTN-USTR Taiwan-US tariff-negotiation chronology and outcomes].

The post-April 2025 tariff-negotiation architecture has been complicated by the cross-Strait architectural dynamics, the parallel TSMC-Arizona-and-CHIPS-Act architecture, and the post-2025 broader US-Asia-Pacific tariff-architecture dynamics. The post-2025 Taiwan tariff-rate has been re-articulated across the post-April 2025 window, with the post-July 2025 architecture producing a substantially lower effective tariff-rate than the initial 2 April 2025 32 per cent rate [TBD-VERIFY: precise post-July 2025 Taiwan effective tariff-rate architecture].

12.3 The New Southbound Architecture's Interaction with the Trump-2 Tariff Equilibrium

The post-April 2025 Trump-2 tariff architecture has re-engaged the New Southbound architecture's strategic-diversification logic. The post-April 2025 Taiwan-export-architecture diversification logic has gained renewed salience under the post-2025 US-tariff-uncertainty environment, with the New Southbound bilateral-trade-architecture providing trade-architecture-diversification options.

The post-2025 New Southbound bilateral-trade-architecture has, however, been complicated by the parallel post-April 2025 reciprocal-tariff rates applied to other Asia-Pacific countries. The April 2025 reciprocal-tariff rates applied to ASEAN countries — including Vietnam (46 per cent), Cambodia (49 per cent), Laos (48 per cent), Indonesia (32 per cent), Thailand (36 per cent), Malaysia (24 per cent), the Philippines (17 per cent), and Singapore (10 per cent) [TBD-VERIFY: precise April 2025 ASEAN reciprocal-tariff rates] — complicated the post-2018 Taiwanese-manufacturing capacity migration from mainland China to ASEAN, since the post-April 2025 ASEAN-located Taiwanese-manufacturing capacity faces substantial reciprocal-tariff rates on its US-export architecture.

The post-9 April 2025 90-day pause and the subsequent post-July 2025 tariff-architecture re-articulation have re-architected the ASEAN-related trade-architecture environment, with substantial post-2025 Taiwan-ASEAN bilateral-trade-architecture re-calibration across the post-April 2025 window. The forward-trajectory question of whether the New Southbound architecture can compensate for any sustained Trump-2-tariff-induced trade-architecture disruption emerges as a central post-2025 strategic-architecture question.

12.4 The 2025–2026 Bilateral-Trade-and-Investment-Flow Trajectory

The 2025–2026 Taiwan-New-Southbound bilateral-trade-and-investment-flow trajectory has been shaped by the post-April 2025 Trump-2 tariff architecture. The 2024 Taiwan-New-Southbound bilateral-trade-flow reached approximately US$180 billion [TBD-VERIFY: precise 2024 Taiwan-New-Southbound bilateral-trade-flow figures], representing the highest annual bilateral-trade-flow across the 2016–2024 New Southbound era. The 2025 Taiwan-New-Southbound bilateral-trade-flow trajectory across the post-April 2025 window has been affected by the global trade-architecture transformation [TBD-VERIFY: precise 2025 Taiwan-New-Southbound bilateral-trade-flow trajectory through Q1 2026].

The post-2025 Taiwanese outbound-investment flow to New Southbound countries has been complicated by the post-April 2025 ASEAN reciprocal-tariff architecture. The pre-April 2025 Taiwanese-manufacturing capacity migration from mainland China to ASEAN had been driven substantially by the post-2018 US-China trade-war and the post-2022 Resilient Supply Chain architecture; the post-April 2025 ASEAN reciprocal-tariff architecture has complicated the post-2018 ASEAN-migration trajectory, with post-April 2025 Taiwanese-manufacturer commentary about the renewed cross-Strait-versus-ASEAN trade-off architecture.

13. The KMT-DPP Contestation — Strategic-Diversification-Success versus Bilateral-Trade-Flow-Modest Framings

13.1 The DPP Strategic-Diversification-Success Framing

The DPP-aligned framing of the New Southbound architecture emphasises the strategic-diversification-success across the 2016–2024 Tsai-era window. The framing emphasises: (i) the cross-Strait-trade-share contraction across the post-2016 window, with the cross-Strait trade-share declining from approximately 26 per cent in 2015 to approximately 22 per cent in 2023 [TBD-VERIFY: precise cross-Strait trade-share trajectory 2015–2023]; (ii) the New-Southbound-trade-share expansion across the same window, with the New Southbound trade-share expanding from approximately 18 per cent in 2015 to approximately 23 per cent in 2023 [TBD-VERIFY: precise New Southbound trade-share trajectory 2015–2023]; (iii) the Taiwan-manufacturer migration architecture from mainland China to ASEAN; (iv) the education-and-people-to-people-exchange architecture; (v) the medical-cooperation architecture.

The DPP-aligned framing further emphasises the soft-power-architecture outcomes of the New Southbound architecture: the eighteen-target-country bilateral-engagement architecture has produced long-term soft-power architecture across the New Southbound countries, with the Taiwan-Connection Programme alumni-network architecture, the One Country, One Centre medical-cooperation architecture, and the post-2017 Indonesian-migrant-worker-cooperation architecture all providing long-term bilateral-engagement architecture foundations.

13.2 The KMT Bilateral-Trade-Flow-Modest Framing

The KMT-aligned framing of the New Southbound architecture emphasises the comparative bilateral-trade-flow modesty of the architecture relative to the cross-Strait baseline. The framing emphasises: (i) the cross-Strait trade-flow remained larger than the New Southbound trade-flow across the entire 2016–2024 window; (ii) the post-2016 cross-Strait trade-share contraction has been driven substantially by external factors (US-China trade-war, semiconductor-and-electronics-supply-chain dynamics) rather than by the New Southbound architecture; (iii) the post-2016 ECFA-partial-maintenance equilibrium has produced cross-Strait economic-architecture continuity notwithstanding the post-2016 political-divergence; (iv) the post-2016 PRC tourist-arrival contraction and the post-2017 PRC student-population contraction have produced economic-architecture costs that the New Southbound architecture has not compensated for.

The KMT-aligned framing further emphasises the question of whether the New Southbound architecture is best read as a trade-and-investment-architecture instrument or as a diplomatic-political-soft-power instrument. The KMT-aligned framing emphasises that the architecture's trade-and-investment outcomes are modest relative to the cross-Strait baseline and that the architecture's political-rhetorical framing has exceeded its trade-and-investment outcomes.

13.3 The 2026 KMT Recall-Aftermath Trade-Policy Architecture Contestation

The post-2025 KMT recall campaign and the post-March 2025 KMT-and-TPP legislative-bloc confrontation with the Lai administration (covered in TW-D-04) has produced trade-policy architecture contestation across the post-2025 window. The post-2025 KMT-aligned legislative-bloc has challenged certain components of the post-2024 New Southbound architecture, including budget-architecture provisions, education-architecture provisions, and Indonesian-migrant-worker-cooperation architecture provisions.

The post-2025 New Southbound architectural contestation has, however, operated within a consensus that the broader strategic-diversification architecture should continue. Neither the KMT nor the TPP legislative bloc has proposed the wholesale dismantling of the New Southbound architecture; the contestation has instead focused on specific architectural provisions, budget allocations, and implementation-architecture choices rather than the wholesale architecture.

13.4 The Diplomatic-Political-Soft-Power versus Trade-and-Investment-Architecture Framings

The question of whether the New Southbound architecture is best read as a diplomatic-political-soft-power instrument or as a trade-and-investment-architecture instrument is a continuing analytical question across both DPP-aligned and KMT-aligned commentary. The architecture's multi-dimensional character — combining trade-and-investment architecture, education-and-people-to-people architecture, medical-cooperation architecture, and multilateral-engagement architecture — complicates the diplomatic-versus-trade analytical binary.

The scholarly assessment (across Bush 2021, Rigger 2021, Glaser, Hsiao, and Templeman) broadly recognises the New Southbound architecture as a multi-dimensional strategic-architecture instrument with both diplomatic-political-soft-power and trade-and-investment-architecture components. The trade-and-investment-architecture outcomes are modest relative to the cross-Strait baseline but substantially significant relative to the pre-2016 baseline; the diplomatic-political-soft-power outcomes are substantial and provide long-term bilateral-engagement-architecture foundations.

14. The 2025–2026 Forward Trajectory and Spiral Index

14.1 The New Southbound Resilience Question under the Post-April 2025 Trump-2 Reciprocal-Tariff Architecture

The 2025–2026 New Southbound architecture trajectory faces resilience questions under the post-April 2025 Trump-2 reciprocal-tariff architecture. The post-April 2025 ASEAN reciprocal-tariff architecture has complicated the post-2018 Taiwanese-manufacturing capacity migration from mainland China to ASEAN, with post-April 2025 commentary about the renewed cross-Strait-versus-ASEAN trade-off architecture. The forward-trajectory question of whether the post-2025 Taiwanese-manufacturer migration trajectory will continue toward ASEAN, return to mainland China, or shift toward other geographic clusters (including India, Mexico, and the European Union) emerges as a central post-2025 strategic-architecture question.

14.2 The CPTPP-Application Trajectory under the Continuing PRC Parallel-Application

The post-2021 Taiwan CPTPP application continues to face trajectory uncertainty under the continuing PRC parallel-application architecture. The post-2024 CPTPP Commission deliberation architecture has produced limited progress on either the PRC or the Taiwan application across the post-2024 window. The forward-trajectory question of whether the post-2026 CPTPP Commission architecture will engage with either application — and whether the parallel-application architecture can be resolved — emerges as a continuing post-2025 multilateral-trade-architecture question.

14.3 The Post-2026-Mid-Term-Election Continuation Question

The post-2026 forward-trajectory question of New Southbound continuation depends on the 2026 nine-in-one local-election outcomes (covered in TW-D-05) and the consequent post-2026 political-architecture dynamics. A 2026 KMT performance — particularly the consolidation of KMT municipal-leadership across multiple major municipalities — would produce post-2026 political-architecture pressure on the Lai-administration's New Southbound continuation architecture. A 2026 DPP performance, conversely, would reinforce the post-2024 New Southbound continuation architecture.

The post-2028 presidential-election architecture (the next presidential election scheduled for January 2028) provides the longer-arc forward-trajectory question. A potential post-2028 KMT federal-government return would produce post-2028 architectural-uncertainty about the New Southbound continuation; a continuing DPP federal-government would reinforce the post-2024 architectural-continuity.

14.4 The Connection to the Broader Taiwan Economic-Strategic-Architecture Transformation

The New Southbound architecture sits within a broader Taiwan economic-strategic-architecture transformation across the 2016–2026 window. The broader transformation includes: (i) the post-2016 cross-Strait economic-decoupling logic and the post-2014 ECFA-partial-maintenance equilibrium (covered in TW-E-01); (ii) the post-2018 US-China trade-war reshoring dynamic and the post-2022 Resilient Supply Chain architecture; (iii) the post-2022 TSMC-Arizona-and-CHIPS-Act architecture and the post-2025 Trump-2 chip-tariff architecture (covered in TW-D-03 and TW-G-03); (iv) the post-2025 Trump-2 reciprocal-tariff architecture and the post-April 2025 bilateral-trade-architecture transformation.

The New Southbound architecture is best read as a component of this broader transformation rather than as a stand-alone architectural innovation. Its trade-and-investment-architecture outcomes have been driven by the broader external dynamics (US-China trade-war, post-2020 supply-chain-resilience emphasis, post-2025 Trump-2 tariff architecture) rather than by the New Southbound policy-architecture itself. Its diplomatic-political-soft-power outcomes have, however, been substantially driven by the policy-architecture itself, with the eighteen-target-country bilateral-engagement architecture providing long-term soft-power-architecture foundations.

14.5 Spiral Index — Forward-Trajectory Document Stubs

The post-2026 forward-trajectory architecture for the New Southbound architecture suggests the following document stubs for subsequent corpus expansion:

TW-E-03: Taiwan in the Post-April 2025 Trump-2 Reciprocal-Tariff Architecture — the post-April 2025 OTN-USTR negotiation chronology, the post-July 2025 tariff-architecture re-articulation, the post-2025 Taiwan-US bilateral-architecture transformation, and the New Southbound architecture's interaction with the post-2025 tariff equilibrium.
TW-E-04: The Taiwan-India Bilateral-Engagement Architecture 2018–2026 — the bilateral-engagement architecture evolution, the post-2022 semiconductor-cooperation surge, the post-2024 mobility-agreement architecture, and the post-2025 strategic-architecture continuation.
TW-E-05: The Taiwan-Vietnam Bilateral-Engagement Architecture 1993–2026 — the longer-arc 1993 Go South baseline through the post-2018 US-China trade-war reshoring dynamic, the post-2020 semiconductor-cooperation architecture, and the post-2025 Trump-2-tariff-architecture impact.
TW-E-06: The Taiwan CPTPP Application 2021–2026 — the post-2021 application architecture, the post-2023 UK-accession precedent, the post-2024 CPTPP Commission deliberation architecture, and the parallel PRC-application complication.
TW-G-05: The Taiwan-India Semiconductor-Cooperation Architecture 2018–2026 — the semiconductor-cooperation architecture evolution from the post-2018 Foxconn investment through the post-2022 Foxconn-Vedanta proposal, the post-2024 PSMC-Tata fab announcement, and the post-2025 continuing semiconductor-supply-chain integration architecture.

The post-2026 forward-trajectory architecture suggests that the New Southbound architecture will continue as a component of Taiwan's economic-strategic-architecture across the post-2026 window, with the bilateral-engagement architecture, the multilateral-trade-architecture engagement (continuing CPTPP application, continuing US-Taiwan Initiative on 21st Century Trade second-tranche advancement), and the cross-Strait-decoupling logic providing the architectural foundations for the post-2026 continuation. The resilience-question under the post-April 2025 Trump-2 reciprocal-tariff architecture, however, will provide the 2025–2026 architectural test.
