Abstract
Security has undoubtedly been a central and continuous feature of ASEAN since its establishment. While it has modified its basic thinking on security and adapted elements of the attendant principles, aims and ways of operation to meet changed circumstances, the level of consistency is still readily observable. Centrality of a different sort has been evident, too, during the post-Cold War period. ASEAN has consciously sought to position itself at the heart of the developing security architecture in both East Asia and the wider Asia-Pacific. The Association has been largely successful at limiting competition and preventing inter-state conflict among its members and at fostering a stable regional order in Southeast Asia (and an incipient one outside of the boundaries of Southeast Asia). Broadly speaking, this stability has been aided and abetted by the policies of the major external powers in whose interests it has been, up until now. The extent to which a stable regional order remains in the interests of the major powers will be one of the great questions for the next phase of ASEAN’s life.
