"Updated papers and discussion summary of a RAND conference held in January 1979 to assess the major political, economic, and military trends likely to shape Asian regional security in the 1980s. Twelve chapters explore the impact of the Sino-Soviet rivalry on the region and the implication of indigenous developments associated with the dramatic economic growth and social transformation of East Asia. Specific issues include extension of the Sino-Soviet conflict to Indo-China; the Soviet military buildup in Asia; America's military presence and role in maintaining a force balance; Japan's new defense mood and future policy directions; the coming "crossover" in power relationships between North and South Korea; continuing rapid economic growth and its political consequences; the regional impact of China's economic modernization program; problems of arms transfers and nuclear proliferation; and the security implications of Asia's growing technological and industrial sophistication. An overview analysis suggests ten choices for a U.S. allied security strategy for the region which will determine the pattern of Asian security relationships in the coming decade. 305 pp. (JD)."--Rand abstracts.
