America’s Response to China has long been the standard resource for a succinct, historically grounded assessment of an increasingly complicated relationship. Written by one of America’s leading diplomatic historians, this book analyzes the concerns and conceptions that have shaped U.S.–China policy and examines their far-reaching outcomes. Warren I. Cohen begins with the mercantile interests of the newly independent American colonies and discusses subsequent events up to 2018. For this sixth edition, Cohen adds an analysis of the policies of Barack Obama and extends his discussion of the Chinese–American relationship in the age of potential Chinese ascendance and the shrinking global influence of the United States, including the complications of the presidency of Donald Trump. Trenchant and insightful, America’s Response to China is critically important for understanding U.S.–China relations in the twenty-first century.
