This research will examine prospects for U.S.-Japan cooperation regarding India and trilateral cooperation among the world's two most powerful and its largest democracies on key issues. The post-Cold War international environment, rising importance of India, and expanded u.s. and Japanese ties to the country form the context for the study. Three case studies will be analyzed. First, the implications of India's closer relations with key Asian states for U.S.-Japanese interests. Second, prospects for U.S.-Japan cooperation with India on civil nuclear power and nuclear weapons proliferation. Finally, the potential for U.S.-Japan cooperation and competition on aid, trade, and investment in India. The study will have a policy focus.
