This chapter assesses the Association of Southeast Asian Nations (ASEAN) regional project as an international regime. Although ASEAN’s regime is underpinned by unique features, certain characteristics of other regional integrations are still evident. Accordingly, ASEAN’s regime is devoid of complete synchrony of state parties’ normative interests and the surrender to implementing institutions of the regional project. Although ASEAN has been lauded as a successful regional integration project, its normative beliefs have been constructed around its identity as a regional project. Indeed, ASEAN member states might have taken inspiration from the EU, but they continue to be highly cautious about institutional arrangements that centralise decision-making and dilute state sovereignty. Hence, the gains of prosperity recorded so far are largely driven by individual countries’ efforts rather than a collective outcome of normative interests and obeisance to the implementing institutions.
