Southeast Asia Caught Between U.S. and China as AI Rivalry Hardens Into Competing Tech Spheres

Southeast Asian governments are increasingly finding themselves squeezed by the escalating contest for artificial intelligence influence between the United States and China, a rivalry that is beginning to resemble two competing technological spheres.

Across the region, many countries have worked for years to preserve constructive relationships with both Washington and Beijing, balancing trade, investment, and security interests. But as AI becomes a strategic priority—tied not only to economic competitiveness but also to national security—officials and businesses are growing more worried that staying equidistant may become harder to sustain.

The United States and China are each promoting their own approaches to AI development and deployment, effectively building separate “blocs” and encouraging other countries to align with their ecosystems. That courtship carries real-world consequences: the standards adopted for AI systems, the suppliers chosen for critical infrastructure, and the regulatory frameworks used to govern data and algorithms can all shape who a country can partner with—and who it may be pressured to avoid.

For Southeast Asia, the stakes extend beyond diplomacy. Companies operating in the region rely on access to technology, cloud services, chips, and cross-border data flows. If geopolitical competition pushes governments to favor one side’s technology stack, firms could face higher costs, compliance challenges, or restrictions on which tools they can deploy. In sectors ranging from finance and telecommunications to manufacturing and e-commerce, decisions about AI vendors and platforms are increasingly intertwined with broader political considerations.

Security considerations are also prominent. AI is rapidly being integrated into cyber defense, surveillance, and military applications, raising anxieties that partnerships in this area could be interpreted as strategic alignment. That, in turn, may affect intelligence cooperation, procurement choices, and the resilience of national digital infrastructure.

The pressure is not necessarily arriving in the form of explicit ultimatums. Instead, it can emerge through procurement rules, export controls, investment screening, and differing expectations around data governance and transparency. As the two powers continue to lead distinct AI ecosystems, Southeast Asian policymakers may find it progressively more difficult to remain fully interoperable with both.

For now, many in the region still aim to keep options open—seeking investment and technology from both the U.S. and China while building their own digital capacity. But the sense is growing that the widening AI rivalry could force uncomfortable trade-offs, reshaping business strategies and security relationships across Southeast Asia.

Why it matters

Southeast Asia’s economies and governments could face higher costs and tougher choices if AI technologies fracture into rival U.S.- and China-led systems. Businesses may need to adapt supply chains and compliance plans, while governments weigh security risks against economic benefits. The next key signals will be shifts in procurement policies, data rules, and technology partnerships that indicate whether the region can stay neutral—or must align.
