"In this important new book, C.H. Kwan asks whether the Japanese yen can, or will, replace the dollar as the key currency in East Asia. Kwan analyzes the implications for Japan and Asia's developing countries should they come together to form a yen bloc?a grouping of countries that use the yen as an international currency and maintain stable exchange rates against the yen. Combining academic analysis with his experience advising the Japanese prime minister and the Japanese minister of finance, Kwan concludes that a yen bloc might benefit Asia's developing countries?as well as Japan?while contributing to a more stable international monetary order. Kwan's book represents the first attempt to explore systematically the possibility of monetary integration in Asia. It also provides a vision for regional integration in Asia in the twenty-first century."
