The global war on terrorism has provided a new context for relations between the United States and China. As the September 2002 National Security Strategy of the United States of America makes clear, cooperation with China on a range of economic, political, security, and military issues increasingly serves U.S. interests. At the same time, this relationship retains elements of competition and the potential for confrontation, compounded by a legacy of periodic crises and mutual wariness. Achieving a national consensus on an appropriate balance in U.S.-China relations, especially in military-to-military affairs, remains a central challenge for those who analyze, formulate, and implement America's China policies.
