The Tibetan Policy Act of 2002 (TPA) is a core legislative measure guiding U.S. policy toward Tibet. Its stated purpose is "to support the aspirations of the Tibetan people to safeguard their distinct identity." Among other provisions, the TPA establishes in statute the State Department position of Special Coordinator for Tibetan Issues and defines the Special Coordinator's "central objective" as being "to promote substantive dialogue" between the government of the People's Republic of China and Tibet's exiled spiritual leader, the Dalai Lama, or his representatives. The Special Coordinator is also required, among other duties, to "coordinate United States Government policies, programs, and projects concerning Tibet"; "vigorously promote the policy of seeking to protect the distinct religious, cultural, linguistic, and national identity of Tibet"; and press for "improved respect for human rights." While the Special Coordinator coordinates Tibet-related U.S. government programs, congressional mandates and earmarked appropriations for most such programs are contained in legislation other than the TPA. The programs include assistance for nongovernmental organizations to work in Tibetan communities in China; an educational and cultural exchange program with "the people of Tibet"; Voice of America and Radio Free Asia Tibetan-language broadcasting into Tibet; assistance for Tibetan refugees in South Asia; a scholarship program for Tibetans outside Tibet; and National Endowment for Democracy programs relating to Tibet. Congress has shown a strong interest in Tibet since the 1980s, passing dozens of laws and resolutions related to Tibet, speaking out about conditions in Tibet, and welcoming visits by the Dalai Lama and, more recently, the political head of the India-based Central Tibetan Administration. Such actions have long been a source of friction in the U.S.-China relationship. China charges that they amount to support for challenges to Chinese rule in Tibet.
