In the midst of the AI race, Southeast Asia thrives. The region has become a landing for tech giants seeking to expand computational capacity and diversify supply chains amid global geoeconomic rivalry. One visible result is the sprawling data centers and technological parks across the region. The Southeast Asian semiconductor industry is catching the same updraft.

Yet a thriving AI boom in Southeast Asia is not an automatic credit on the Association of Southeast Asian Nations’ (ASEAN) side of the ledger. The AI race unfolding in the region is a race between Southeast Asia’s 11 sovereign member states. For investors, the region isn't much of a single choice but rather a menu of competing destinations, with each country offering different levels of resource availability, location connectivity, and talent capacity.

The sales pitch for Southeast Asia hinges on what ASEAN provides in regional cohesion. The ASEAN Digital Economy Framework Agreement (DEFA) marks an important step toward more substantive regional coordination underpinning the tech boom. So too should the decades-long aspirations for the ASEAN Power Grid (APG) be to connect the region’s power networks and collectively boost its energy security and renewability. The regional peace and stability that ASEAN underwrites the relatively safe environment for foreign direct investment (FDI) as it looks for alternatives to older chip hubs in Northeast Asia.

But the Southeast Asian digital economy isn’t really an ASEAN achievement yet.

Malaysia is the fastest-growing data center market in Southeast Asia, gaining ground after its southern neighbor Singapore issued a moratorium in 2019 on new data centers due to constraints on Singapore’s land, water, and energy. Vietnam, Thailand, the Philippines, and Indonesia are emerging as destinations for large-scale projects including from Amazon Web Services, Microsoft, and Google. By early 2026, hyperscalers had invested more than US$50 billion worth of AI-ready data center and cloud infrastructure across the region.

The region has long occupied the back end of the semiconductor supply chain in assembly, testing, and packing (ATP), and accounted for 23.6% of global chip exports in 2023. Vietnam and the Philippines are rapidly expanding their role in ATP and other back-end processes, while established hubs such as Malaysia and Singapore are seeking to capture higher-value segments in chip design and fabrication.

To compete for tech investments, Southeast Asian nations offer different fiscal and regulatory incentives. Vietnam, home to low-cost, high-skilled workers, offers a preferential 10% corporate income tax rate for the first 15 years, compared to the normal 20% rate. It scrapped personal income tax derived from research and innovation activities. In Thailand, AI companies are eligible for 100% foreign ownership, relaxed working permits, and up to eight years of tax exemptions. Indonesia offers the most generous tax breaks of up to 20 years for AI and data center FDI.

But a race pursued individually cannot deliver the same leverage that the region could wield collectively. Competing fiscal and regulatory concessions weaken each government’s individual bargaining power. Some key infrastructure underpinning the AI economy, such as power grids, subsea cables, and cloud services, increasingly extends across national borders. ASEAN is nowhere near creating the supranational authority nor act sufficiently as a single economic bloc in ways that might amplify gains from the individual races into collective leverage for the region.

ASEAN may benefit from stronger coordination where national AI projects depend on shared infrastructure. The association could do more to even out asymmetric cross-border resource and environmental pressures arising from AI projects. Its regional standards affect the region's collective bargaining position.

Despite three decades of envisioning a single market and production base, the region still has stark structural asymmetries across its economies, including per capita GDP and differentiated types of resource wealth across its 11 states. Many of these asymmetries are the result of governance choices and deliberate policies taken by each Southeast Asian nation’s government.

Much of these asymmetries is the result of governance choices and deliberate policies taken by each Southeast Asian nation’s government. The disparities are not an indictment of ASEAN’s achievements. But they make for weaker regional governance enforcement and a level of cohesion that often appears more symbolic than binding. The region’s response to United States’ “Liberation Day” tariffs is telling. Calls were made publicly from many ASEAN member states for a coordinated response, even as member states instead pursued separate bilateral tariff deals with Washington, forgoing the greater bargaining power they might have exercised collectively.

It’s a patchy record. Scheduled to be formally signed in November 2026, DEFA is set to become the first region-wide binding agreement for the digital economy including cross-border data flows, electronic payments, and AI.

As that digital economy expands, it increasingly makes the case for ASEAN stepping up to coordinate the demands on the physical resources and infrastructure across the region. The region’s AI buildout has consequences that increasingly extend beyond national borders. Meeting network needs such as subsea cables and energy grids will likewise require unprecedented cooperation among ASEAN member states.

The case for faster and bolder ASEAN integration extends beyond managing shared resources and cross-border infrastructures, but linking it to currently fragmented capabilities to capture greater regional value from the AI economy. The ASEAN Framework for Integrated Semiconductor Supply Chain (AFISS) acknowledges this imperative, seeking to link capabilities across the region’s disparate comparative strengths in raw material extraction, design and manufacturing, testing, and commercialization.

External pressures are complicating the challenges for a more united ASEAN. Singapore and the Philippines are the only two ASEAN members who were invited to join the US-led Pax Silica initiative to create secure AI supply chains among “trusted allies.” Malaysia, Indonesia, Laos, Cambodia, and Myanmar are in the new China-led AI-focused intergovernmental World Artificial Intelligence Cooperation Organization (WAICO), created in July 2026.

Such diversity might contribute to ASEAN’s diplomatic flexibility and the region’s vaunted neutrality. However, stronger regional coordination is required to ensure that diverging geoeconomic alignments do not come at the expense of the regional collective agency to influence the rules on trade and investment affecting the region.

Another test for ASEAN’s coordination lies in the surging power demand from AI infrastructure. In particular, it is a test for the APG, the association’s longstanding vision of connecting national electricity networks and supplying power equitably across the region.

After decades of slow progress, momentum behind the APG has rarely been stronger with an enhanced memorandum of understanding among member states, endorsement of the related ASEAN Submarine Power Cable Development Framework initiative to enable cross-border electricity integration, and the launch of APG Financing Initiative. Yet the race for AI infrastructure could pull these regionalizing instincts the opposite direction, resulting in more or less a repeat of how the region responded to Liberation Day tariffs.

In Southeast Asia, the AI boom is posing the question of whether ASEAN can overcome its structural and institutional constraints. If so, Southeast Asia’s collective leverage can make ASEAN not just a provider of value but a shaper of the AI economy.
