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.

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.
