Regionalism's multiple negotiations: ASEAN in East Asia.

This article explains East Asian regionalism as the product of two sets of negotiations. The first negotiation is between East Asia on the one hand and global forces and structures on the other. The second negotiation is intra-regional and includes a critical negotiation between the Association of Southeast Asian Nations (ASEAN)-Southeast Asia and East/Northeast Asia, which also provides the primary focus of this article. This article details ASEAN's extensions into East Asian regionalism as part of interdependent efforts to adapt transitioning global and regional systems. Conceiving these regional negotiations to be not just economic and utilitarian but first and foremost normative, this article details the opportunities and dilemmas represented by 'East Asia' for ASEAN, ASEAN-Southeast Asia and Southeast Asia as a meaningful organizing principle. Dilemmas associated with the ASEAN Plus Three process, an East Asia free-trade area and the ASEAN Charter provide illustrations of East Asia's understood challenges for Southeast Asia in addition to the ways that Southeast Asian agencies have been shaping the form and content of recent East Asian efforts and also how regional-global and intra-ASEAN negotiations continue to provide key constraints.
