Economic Integration and Trade Policy in East Asia
Summary
Economic integration in East Asia has advanced through a succession of overlapping agreements and evolving policy frameworks that have reshaped production networks, trade flows and regional governance. Beginning with the creation of the ASEAN Free Trade Area and the subsequent ASEAN Economic Community, member states progressively deepened tariff liberalisation, harmonised standards and facilitated investment. Parallel initiatives such as the ASEAN+3 and ASEAN+6 processes laid the groundwork for broader partnerships, culminating in the Regional Comprehensive Economic Partnership (RCEP), which entered into force in 2022 and now constitutes the world’s largest free-trade zone. Complementary arrangements, including the Comprehensive and Progressive Agreement for Trans-Pacific Partnership, further diversify market access and regulatory cooperation. These networks have fostered the emergence of factory clusters, cross-border value chains and special economic zones, allowing East Asian economies to leverage comparative advantages in electronics, automotive parts, textiles and increasingly in green and digital technologies. Policymakers have sought to balance liberalisation with safeguards against sudden shocks, deploying non-tariff measures to protect sensitive sectors even as they pursue deeper collaboration on customs procedures, intellectual property and sustainable development. The resulting integration has boosted intra-regional trade, attracted foreign direct investment and contributed to resilient growth, while also raising questions about distributional impacts, competition policy and the governance of megaregional agreements.
Research from Nature Portfolio
Recent studies have employed bibliometric and visualisation techniques to map the evolution of RCEP research. By analysing over three hundred peer-reviewed articles published since 2012, researchers have identified shifting thematic clusters, from traditional economic impact assessments towards interdisciplinary inquiries into environmental sustainability, digital governance and social dimensions. Network analysis reveals an expanding constellation of journals and co-citation patterns that signal growing interest beyond core trade economics, pointing to emerging fields such as data-driven policy modelling and the integration of supply-chain resilience with regional development goals.

Technical terms
Regional Comprehensive Economic Partnership (RCEP): A multilateral free-trade agreement among East Asian and Pacific economies aimed at reducing tariffs, aligning rules of origin and facilitating supply-chain integration.
Computable General Equilibrium (CGE) model: A quantitative framework that simulates how economies respond to policy changes by balancing supply and demand across multiple sectors and regions.
Value-added trade: The measurement of the economic value added by each country in the production of goods and services as they cross borders, rather than the total gross exports.
Non-tariff barriers: Regulatory and procedural measures—such as quotas, licensing requirements and technical standards—that affect trade in addition to customs duties.
