The idea of an East Asia economic integration was first rooted in the foundation of the Association of Southeast Asian Nations (ASEAN) in 1967. Due to the great power rivalry in Southeast Asia area and the intra-ASEAN power conflicts, however, there had been little achievement regarding the regional economic integration in ASEAN's early years. After the 1997 Asian financial crisis that devastated most East Asian economies, those hit most by the slump in ASEAN, together with South Korea and Hong Kong, began to realize the fact that it was imperative to establish a system of closer regional economic cooperation to make the region more resilient and less vulnerable to similar attacks in the future. The crisis thus catalyzed East Asian efforts towards greater economic integration. At the present time, economic integration in East Asia is looming to take the "hub and spoke" characteristic under the forms of ASEAN-plus-three (10+3) and ASEAN-plus-one (10+1), in which the ASEAN members take the lead, China, Japan and South Korea the relatively late-comers. Unfortunately, Taiwan has been totally excluded from participation in the moves toward deeper economic integration in East Asia despite its close investment and trade ties with the region. As a result, we need to move with all possible haste to formulate a workable strategy to respond to this changing environment and to avoid becoming marginalized from the process of Asian economic integration.
