This book examines how since about 2008 the economy of Taiwan has become ever more deeply integrated into the economy of China. It goes beyond a consideration of trade and investment flows, and discusses also the large population flows, the growing integration of the two financial systems and the nature of the deep economic integration at the industry and firm level. It considers the impact of growing economic integration on society and politics, assesses how China-Taiwan economic integration is affecting the East Asian region more widely, and explores the implications for international relations, including the United States dominance in the region. Overall, the book presents a comprehensive analysis of all the issues.
