The relationship between the United States and China is probably the most important current bilateral tie in the world. In his new book America’s Challenge – Engaging a Rising China in the Twenty First Century, Michael Swaine at the Carnegie Endowment for International Peace interviews over 50 current and former U.S. officials in an effort to identify current problems and challenges in U.S.-China relations, evaluate policies adopted by the U.S. government, and propose ways to improve the relationship.
