Economic integration in Southeast Asia is expanding beyond trade and investment to address supply chain disruptions, digital fragmentation, energy insecurity, and the need for more inclusive growth.

Economic cooperation in ASEAN is entering a new phase. For decades, Southeast Asia pursued integration to achieve growth, competitiveness, trade, and attract foreign direct investment (FDI). Those goals still matter, but ASEAN’s members face growing trade tensions, supply chain disruptions, energy challenges, and rapid technological change. Regional cooperation must therefore also serve to strengthen economic security, resilience, and inclusive growth.

The region’s economic integration gained momentum with the 2003 foundation of the ASEAN Economic Community (AEC), which aimed to create a single market and production base. The goal was to attract FDI and strengthen ASEAN’s competitiveness as major Asian economies expanded.

The group pursued two tracks. It deepened regional integration through trade, services, investment, infrastructure, and connectivity. It also signed free trade agreements (FTAs) with partners including the People’s Republic of China (PRC), Japan, India, the Republic of Korea, and Australia and New Zealand. The aim was to strengthen ties within Southeast Asia while remaining open to the global economy.

The case for regional cooperation has evolved recently. The COVID-19 pandemic showed that ASEAN countries must work together not only to limit economic disruption, but to aid recovery and to adapt to better cope with future shocks. It also drove more use of digital tools by businesses, governments, and households. This has increased the need for shared systems, common standards, trusted digital infrastructure, and cross-border digital trade.

The pandemic also highlighted the need to address cross-border risks. Disasters, extreme weather, and energy disruptions can interrupt supply chains, making regional action essential. Deeper integration has not automatically delivered benefits to all. Many small businesses still lack finance, technology, skills, and market access, limiting their ability to benefit from regional opportunities.

Recent shocks affecting trade and energy markets reinforced this shift. ASEAN cooperation is now needed not only to promote trade and investment, but also to improve economic security, build resilience, and ensure growth reaches more people and businesses. ASEAN’s cooperation on trade, the digital economy, and cleaner energy is increasingly aligned with this broader objective.

Trade and digital systems for a more resilient region

The group’s trade architecture is evolving to strengthen resilience. ASEAN and PRC, for example, upgraded their FTA last year to add the digital and green economy, and supply chain connectivity. These provisions help promote greater participation of smaller firms while strengthening resilience and regional integration.

The Regional Comprehensive Economic Partnership (RCEP) offers significant potential to boost trade and investment while strengthening economic security and resilience. By unifying trade rules and lowering tariffs across 15 member countries, it provides a predictable, rules-based framework that strengthens supply chains and buffers against protectionism, pandemics and global disruptions. Of course, its impact depends on effective implementation and utilization—a review in 2027 offers an opportunity to address new issues and advance integration. The objective is not to retreat from globalization, but to make it more resilient.

ASEAN cooperation is on a pathway to adapt to a more complex and uncertain world.

Similarly, digital cooperation strengthens supply chain resilience and inclusion. The Digital Economy Framework Agreement (DEFA), which advances ASEAN’s past work on e-commerce, payments, paperless trade, cybersecurity, data governance, and others, reiterates the importance of systems that work together to reduce regulatory and operational barriers. By addressing issues such as different compliance requirements and fragmented payment systems, the agreement can help smaller businesses access regional markets and lower transaction costs.

While the agreement’s success will depend on the pace and integrity of implementation, with more regulatory alignment and connectivity, it supports ASEAN’s objectives of greater competitiveness, supply chain resilience and inclusive growth.

Finally, energy cooperation strengthens energy security and resilience during times of supply disruptions. The ASEAN Power Grid (APG) provides a regional platform for electricity trade, enabling countries to balance energy demand, diversify supply sources, and integrate renewable energy. This can reduce exposure to country-specific supply disruptions and global energy price shocks.

The Lao PDR-Thailand-Malaysia-Singapore Power Integration Project demonstrates this potential: Lao People’s Democratic Republic’s (PDR) hydropower is transmitted through Thailand and Malaysia to Singapore, linking four markets through an aligned trading arrangement. The project shows how regional power connectivity can diversify energy supplies, support renewable integration, and strengthen broader economic resilience and energy security.

Turning regional agreements into shared gains

That said, ASEAN cooperation is on a pathway to adapt to a more complex and uncertain world. Growth, openness, and regional integration remain central, but it is also adapting practical ways to address trade tensions, supply chain disruptions, energy insecurity, and rapid technological change.

Admittedly, trade, investment, digitalization, and energy are increasingly linked. Foreign Direct Investment can diversify production, transfer technology, and strengthen regional value chains. Digital integration can improve efficiency and help firms respond more effectively to shocks. Energy cooperation can improve security and make power supplies more resilient.

ASEAN’s next phase of cooperation can treat resilience and economic security as core goals alongside competitiveness, trade, and investment. That will require countries to put agreements into practice, align rules, and ensure that smaller businesses and households share in the gains.
