Abstract
In April 1999, ASEAN formally admitted Cambodia thereby completing its declared goal of grouping together all ten Southeast Asian countries under its umbrella. This was the culminating event in the latest phase of ASEAN's enlargement. This process, however, had been problematic from the start. The entry of Cambodia, Laos, Myanmar and Vietnam without any clear criteria for admission has raised questions regarding the preparedness of these countries to participate in ASEAN. More importantly, it led to strains in ASEAN's relations with its dialogue partners over the legitimacy of some of the governments in power in these countries. The was further complicated by the economic upheaval caused by the financial crisis which struck Southeast Asia in 1997. The impact of these events on ASEAN has put into question the association's growing role as a leading player in Asia-Pacific affairs. More importantly, it has raised issues which are central to ASEAN's continued existence.
