Both the United States and China seek to deepen their economic engagement with the 10 Association of Southeast Asian Nations (ASEAN) members: Brunei Darussalam, Burma, Cambodia, Indonesia, Laos, Malaysia, the Philippines, Singapore, Thailand, and Vietnam. ASEAN countries are seeking to further integrate their economies and create an economic community by the end of 2015. According to International Monetary Fund data, if ASEAN countries were a single nation, their collective 2014 GDP would represent the seventh largest economy in the world. In 2011, the President announced a renewed focus—known as the rebalance—on the Asia-Pacific region. The U.S. Department of State and U.S. Agency for International Development prepared a 5-year strategy for the rebalance. This book examines what available data indicate about U.S. and Chinese trade and investment with ASEAN countries and what actions the U.S. and Chinese governments have taken to further economic engagement with these countries.
