Congress has long been concerned about whether U.S. policy advances the national interest in reducing the role of the People's Republic of China (PRC) in the proliferation of weapons of mass destruction (WMD) and missiles that could deliver them. China has taken some steps to mollify U.S. concerns about its role in weapons proliferation. Skeptics question whether China's cooperation in weapons nonproliferation has warranted President Bush's pursuit of stronger bilateral ties. This report discusses the national security problem of China's role in weapons proliferation and issues related to the U.S. policy response, including legislation, since the mid-1990s.

Despite apparently consistent statements in over three decades, the "one China" policy concerning Taiwan remains somewhat ambiguous and subject to different interpretations. Questions have arisen about the policy itself and about the policy in relation to U.S. interests regarding peace and stability. This report discusses U.S. policy on the "one China" policy in regards to three major issues: sovereignty, use of force, and cross-strait dialogue. Since the mid-1990s, U.S. interests in preventing conflict across the Taiwan Strait have been challenged by China's military modernization and Taiwanese moves toward independence that have been perceived in Beijing as provocative. This report describes these issues in detail, including relevant legislation.
