In the face of the financial crisis of East Asia in 1997, Japan successfully pressed forth the Miyazawa Plan and other efficient rescue packages while the IMF and the World Bank failed to present effective programs. With its presence established, Japan kept playing a leading role in formulating the Chiang Mai Initiative which facilitated bilateral and regional economic cooperation in the area. Based on the analysis of this process, the book examines the ways in which East Asia has grappled with the regional integration of the economies of the area. The study focuses upon competing developmental models, the effects of FTA and EPA, the initiatives of ASEAN, investments and trades in the region. The contributors to the book then inquire what can be done in financial and monetary domains with a special attention paid to the effects of the depreciation of currencies and the consequences of the IMF emergency policies. The study also addresses the issues of productivity, problems of agrarian small states and difficulties of the socially weak in the region.
