Southeast Asia on Edge: Navigating a New Era of Great Power Competition
Southeast Asia is facing a growing challenge as the reliability of traditional security guarantees diminishes. This is particularly acute as the possibility of a crisis involving Taiwan increases, not necessarily through direct targeting of the region, but due to the operational and political pressures stemming from great power conflict. The region’s future hinges on its ability to adapt and proactively address these evolving dynamics.
China’s Shadow and Shifting US Commitments
China is closely monitoring the United States’ responses to global challenges, including situations in Iran and Ukraine, before making any decisions regarding Taiwan. The People’s Liberation Army (PLA) views Southeast Asia as crucial to any potential Taiwan contingency, specifically tasking its Southern Theatre Command with securing its southern flank. This means Southeast Asian nations will inevitably face difficult choices regarding access to their airspace and waters, and the sustainability of defense partnerships.
However, current regional planning often focuses on logistical concerns – primarily citizen evacuation – rather than the broader strategic implications of a Taiwan crisis. Assumptions of external support, from either China or the United States, dominate planning, overlooking the complex decisions that will arise after evacuations are completed. These decisions – granting access, sustaining basing arrangements, or supporting external operations – are fundamentally strategic, not logistical.
The Erosion of US Forward Deployment
The conditions that historically supported long-term US military presence are weakening. Domestic pressures in the US are increasing calls for more conditional burden-sharing and questioning open-ended global commitments. Simultaneously, the US retains the capacity to impose costs on allies who align too closely with China, leaving Southeast Asia vulnerable to both abandonment and coercion.
Other potential security providers are unlikely to fill any void. Japan will likely prioritize crises closer to home, particularly those related to Taiwan, while India focuses on its disputes with China and Pakistan, and the western Indian Ocean. This leaves Southeast Asia with limited external support options.
Beyond Alignment: A Regional Approach to Defense
Simply deferring to China’s position on Taiwan doesn’t resolve the underlying challenges. While it might avoid immediate confrontation, it doesn’t guarantee protection if the military balance shifts. Neutrality, similarly, doesn’t address the spillover pressures from a Taiwan contingency. Without the ability to deny external access and resist coercion, neutrality becomes a vulnerable position.
A more effective approach involves rethinking defense beyond purely national terms, and considering the wider regional space. This doesn’t necessitate new ASEAN mechanisms or collective defense pacts, which are politically unrealistic. Instead, it requires a shift in perspective.
Strategic Geography: A New Framework
This new approach centers on understanding and leveraging Southeast Asia’s strategic geography. It involves:
- Mapping key avenues of advance for external powers.
- Identifying critical terrain, chokepoints, and vulnerabilities.
- Concentrating efforts on positions each state can credibly defend without overextending itself.
States should contribute based on calculated self-interest, not solely on solidarity. Instability stemming from great power competition can reduce the strategic depth available to countries further south, shrinking their buffer zones and exposing defensive lines. Focusing on defending immediate approaches while maintaining the ability to maneuver further afield is crucial.
This approach doesn’t eliminate the choice between alignment and neutrality, but it alters the conditions under which those choices are made. It enables states to manage spillover pressures and prevent operational necessities from dictating foreign policy outcomes. It’s a flexible framework applicable to crises involving any external actor.
The Path Forward: Regional Awareness and Calculated Contributions
A Taiwan contingency will inevitably impact Southeast Asia. Regardless of alignment, all states will face similar operational demands. The key question is whether they can sustain their chosen positions under pressure. Without the capacity to manage these pressures, foreign policy becomes reactive rather than strategic.
Pro Tip: Invest in comprehensive strategic assessments that map your nation’s vulnerabilities and potential contributions to regional security. This proactive approach will strengthen your negotiating position and enhance your resilience.

A: The sources indicate that a 2027 invasion is considered unlikely, but coercive actions around Taiwan and the Indo-Pacific are expected to continue.
Q: What role can ASEAN play in this evolving landscape?
A: The article suggests that new ASEAN-based mechanisms are politically unrealistic, but a shift in regional thinking about defense is crucial.
Q: How can smaller Southeast Asian nations protect themselves?
A: By focusing on defending their immediate approaches and maintaining the ability to maneuver, rather than attempting to project power regionally.
