ASEAN’s Indispensable Paradox: One Region, Multiple Fault Lines

Hosted by the Saw Swee Hock Southeast Asia Centre
LSE Cheng Kin Ku Building, Room LG.03 - Thai Theatre (CKK.LG.03)
Monday 12 October 2026 5pm - 6.15pm

Speaker

Prof Thitinan Pongsudhirak

To the extent that Southeast Asia has no other institution or organisation that can plausibly represent, convene and provide agency for the region as a whole, ASEAN remains indispensable. Yet the 11-member bloc is also increasingly divided and impaired at a time when intensifying great-power rivalry, geoeconomic fragmentation and the erosion of the international order make regional cohesion and ASEAN centrality more necessary.

Ahead of the year-end ASEAN summit season and beyond, this seminar examines the widening gap between ASEAN’s centrality and its capacity. Three fault lines are particularly instructive as ASEAN moves forward. Myanmar has exposed the limits of consensus and ASEAN’s inability to enforce political commitments. The Thai-Cambodian border tensions demonstrate how nationalism and bilateral conflict can cut across regional solidarity from within. In the South China Sea, divergent interests, threat perceptions and relationships with Beijing continue to impede a common ASEAN position amid mounting US-China competition. These are not ASEAN’s only faultlines but indicators of a bigger challenge in maintaining regional agency without strategic unity. While ASEAN is unlikely to become a cohesive geopolitical actor, Southeast Asian states and societies need ASEAN more, not less, as a buffer, bridge and broker among the great powers as the international system becomes more contested and oriented towards self-help.
