Political and economic trends in post-Cambodia ASEAN converge in a new regionalism that seeks, not only to expand membership to include all the Southeast Asian countries (bar East Timor), but to redefine the intra-ASEAN tariff regime in tandem with the economic dynamism of the region. As highlighted by Vietnam's accession to ASEAN membership in 1995, the grouping also seeks to establish a new security regime, albeit with active US participation. Such widening and deepening of ASEAN has not been without attendant problems, however, ranging fron national-territorial issues to universalist claims from within and without the region for greater rights than those conferred by mere economic development.
