This CRS Report discusses China’s suspected acquisition of U.S. nuclear weapon secrets, including that on the W88, the newest U.S. nuclear warhead, since the late 1970s. This current controversy, began in early 1999, raises policy issues about whether U.S. security is further threatened by the PRC’s suspected use of U.S. nuclear weapon secrets in its development of nuclear forces, as well as whether the Administration’s response to the security problems is effective or mishandled and whether it fairly used or abused its investigative and prosecuting authority.

The bid by the China National Offshore Oil Corporation (CNOOC) to acquire the U.S. energy company Unocal for $18.5 billion raised many issues with U.S. policymakers. This report provides an overview and analysis of the CNOOC bid, U.S. interests, implications for U.S. energy security, U.S. investment in the PRC’s (People’s Republic of China’s) oil industry, the process for reviewing the security and other implications of foreign investment in the United States, Congressional activity, and a listing of unresolved issues.

Since its founding in 1949, the People’s Republic of China (PRC) has exerted great effort in manipulating the flow of information and prohibiting the dissemination of viewpoints that criticize the government or stray from the official Communist party view. The introduction of Internet technology in the mid-1990’s presented a challenge to government control over news sources, and by extension, over public opinion. While the Internet has developed rapidly, broadened access to news, and facilitated mass communications in China, many forms of expression online, as in other mass media, are still significantly stifled. This report discusses the history of this issue and examines the U.S.'s response.

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.

This report discusses a list of economic sanctions that the United States currently maintains against China. The influence of Congress on U.S. policy toward China, once significant because so much hung on the annual possibility that favorable trade terms could be suspended, has more recently been diffused. Sanctions that remain in place today can all be modified, eased, or lifted altogether by the President, without congressional input.
