Trade liberalization, growth, and sustainable trade

Trade liberalization has been fundamental to the Association of Southeast Asian Nations’ (ASEAN) economic rise. A network of free trade agreements (FTAs), beginning with the ASEAN Free Trade Area in 1992, created a predictable and open environment for investors. These agreements expanded market access and reinforced the region’s role in global supply chains.

ASEAN’s bilateral FTAs with key partners, including China, Japan, South Korea, India, Australia, and New Zealand, strengthened its position as a hub for international trade and investment. The Regional Comprehensive Economic Partnership (RCEP), signed in 2020, represents the culmination of these efforts. It is projected to add US$209 billion annually to global incomes and US$500 billion to world trade by 2030, reinforcing ASEAN’s central role in regional integration.

This liberalized trade environment enabled ASEAN to build a powerful ecosystem for foreign direct investment (FDI). Singapore emerged as a key financial and technological hub, facilitating capital flows and knowledge transfer. Regional supply chains, with China as a final assembly point, allowed ASEAN economies to specialize in intermediate goods and components, driving efficiency and competitiveness.

The integration of global firms into ASEAN’s production networks highlights this success. Companies such as Apple rely heavily on suppliers across East Asia, with increasing diversification into Southeast Asia. Contract manufacturers like Foxconn and intermediaries such as Li & Fung have played a crucial role in linking global demand with regional production.

At the same time, ASEAN’s economic model is evolving toward more sustainable and technology-driven growth. Venture capital investment reached US$8.2 billion in 2020, supporting sectors such as e-commerce, mobility, and financial technology. Start-ups like Grab and GoTo reflect the region’s growing digital economy.

However, sustainability remains a challenge. While trade liberalization has driven growth, it has not always aligned with environmental and social objectives. The next phase of development will require integrating sustainability into trade and investment frameworks without undermining competitiveness.

Sustainable trade and WTO rules: challenges ahead

The global trading system, anchored by the World Trade Organization (WTO), has historically supported ASEAN’s growth by providing a rules-based framework for trade. Today, that system is under strain. Dispute settlement mechanisms have weakened, and progress on new rules has stalled, limiting the WTO’s ability to address emerging challenges.

This erosion complicates efforts to advance sustainable trade. Issues such as environmental protection, labor standards, and digital governance require coordinated global rules, yet diverging national policies are creating fragmentation. Regional agreements like RCEP fill some gaps but lack comprehensive provisions on sustainability, labor, and environmental standards.

Geopolitical tensions further undermine the multilateral system. The rivalry between the US and China raises the risk of decoupling, which could split global trade into competing blocs. For ASEAN, such fragmentation would be particularly damaging, as its economic model depends on openness and integration across multiple markets.

Deglobalization trends add to these challenges. Protectionist policies in major economies calls for reshoring which threatens to reduce FDI flows. The Covid-19 pandemic reinforced these concerns, with FDI into ASEAN falling by 25% in 2020 to US$136 billion. Although this decline reflects temporary disruptions, it highlights the vulnerability of investment flows to global shocks.

Sustainability pressures are also intensifying. Investors and regulators are demanding higher environmental, social, and governance (ESG) standards, but ASEAN’s progress has been uneven. The region remains heavily reliant on coal, with more than 80% of global coal power capacity under construction located in Asia. Deforestation and environmental degradation continue to pose risks, particularly in countries like Indonesia.

Without stronger multilateral rules and enforcement mechanisms, advancing sustainable trade will remain difficult. The current system is increasingly fragmented, with uneven standards and limited coordination.

Sustainable development and the road ahead for the WTO

The path forward for ASEAN and the WTO will depend on adapting to a more complex and multipolar global environment. ASEAN’s strength lies in its flexibility and diversity, which allow it to attract investment across a wide range of industries and development levels. This diversity will be critical as companies seek alternatives to China and reconfigure supply chains.

Projections highlight the region’s potential. By 2030, ASEAN could generate up to US$600 billion in additional manufacturing output, increase annual FDI by US$22 billion, and create 140,000 new jobs each year. Capturing this opportunity will require maintaining openness while addressing emerging risks.

Sustainable development must become central to this strategy. ASEAN countries face significant climate risks, including rising sea levels and extreme weather. At the same time, global investors are increasingly prioritizing ESG compliance, making sustainability a key determinant of investment flows.

Multilateral institutions, including the World Bank and the Asian Development Bank, can support this transition by promoting higher environmental and social standards. Private sector actors are also playing a role, with global companies and financial institutions pressuring suppliers and borrowers to adopt more sustainable practices.

However, progress remains uneven. While some international banks have reduced exposure to polluting sectors, local institutions often continue to finance them. Similarly, corporate commitments to sustainable supply chains have not always translated into measurable outcomes.

For the WTO, the challenge is to remain relevant in this evolving landscape. Reform efforts must address digital trade, state subsidies, and sustainability while restoring confidence in dispute settlement mechanisms. Achieving consensus among major economies will be difficult, but incremental progress is essential to prevent further fragmentation.

Conclusion

ASEAN’s rise as a global manufacturing and investment hub is one of the most remarkable economic success stories of the modern era. Driven by FDI, trade liberalization, and integration into global supply chains, the region has achieved rapid growth and significant improvements in living standards.

Yet the foundations of this success are shifting. Geopolitical tensions, deglobalization, and climate change are reshaping the global economy, creating new risks and uncertainties. ASEAN’s heavy reliance on foreign investment makes it particularly vulnerable to these changes.

The region’s future will depend on its ability to adapt. This includes maintaining openness to trade and investment, navigating geopolitical rivalries without taking sides, and integrating sustainability into its economic model. Strengthening ESG standards and aligning climate commitments with investor expectations will be critical.

Efforts to build the ASEAN Economic Community by 2025 provide an opportunity to address these challenges. By embracing sustainable development and reinforcing its role in global trade, ASEAN can continue to attract investment and sustain growth.
