Summary: Despite apparently consistent statements in over three decades, the "one China" policy concerning Taiwan remains somewhat ambiguous and subject to different interpretations. Apart from questions about what the "one China" policy entails, issues have arisen about whether U.S. presidents have stated clear positions and have changed or should change policy, affecting U.S. interests in security and democracy. In Part I, this CRS Report discusses the "one China" policy since the United States began in 1971 to reach presidential understandings with the PRC government. Part II documents the evolution of policy as affected by legislation and articulated in key statements by Washington, Beijing, and Taipei. This report will be updated.
   
   Summary: This CRS Report, updated as warranted, discusses the security problem of China’s role in weapons proliferation and issues related to the U.S. policy response since the mid1990s. China has taken some steps to mollify U.S. concerns about its role in weapons proliferation. Nonetheless, supplies from China have aggravated trends that result in ambiguous technical aid, more indigenous capabilities, longer-range missiles, and secondary (retransferred) proliferation. According to unclassified reports to Congress by the intelligence community, China has been a "key supplier" of weapons technology, particularly missile or chemical technology. Policy issues in seeking PRC cooperation have concerned summits, sanctions, and satellite exports.
   Summary: This report outlines recent activities and future plans in China’s civilian space sector. It also discusses benefits and trade-offs of possible U.S.-China collaboration in space, as well as several options to improve space relations, including information exchange, policy dialogue, and joint activities.
