This book focuses on the activity of the Soviet Union in Southeast Asia and the effects of Soviet policy on the region from 1969 to the time of first publication in 1986. In particular, Leszek Buszynski examines the rivalry between the Soviet Union and China, Soviet presence in Vietnam, and the responsive efforts of surrounding regions towards collective security. U.S. policy in the region is a key consideration, particularly in terms of American attempts to placate China and encourage Japan to assist in the defence of the region. With a concluding assessment of regional trends and possible outcomes, this is an important and valuable work for students and scholars with an interest in the history and politics of international diplomacy in Southeast Asia.
