「第三方介入」協助談判僵局之解決，是學界普遍認為可行且具實質效益的方法。中國與西藏流亡政府間，不乏第三方介入的身影，甚至以實際行動促成了九次正式的談判，惟持續的接觸與對話，非但未能建立中藏間彼此的信任和尊重，反使雙邊關係更為惡化。 本研究將1950年代達賴流亡印度後至今，劃分為四個時期，彙整各階段之國際政經情勢、中藏對外政策，及第三方涉藏行動，觀察三者間相互的關連性，深入了解國際介入西藏問題的背景，進而以此作為分析回顧「2002-2010年中藏九次談判」的基礎。探討中國政府和西藏流亡政府之談判訴求、各國相關回應，檢視第三方立場與策略行為，對中藏關係所產生的影響和轉變，從而了解國家行為者居中所扮演之角色，與中藏談判深陷僵局的原因。 / “Third-party Intervention” is generally considered a feasible and beneficial strategy for resolving negotiation deadlock. It has been used in the dilemma of China and Tibetan government-in-exile. There have been nine formal negotiations between both parties urged by the third party. However, instead of help establishing trust and respect between China and Tibet, the negotiations have led to a deterioration of bilateral relations. This study divides the period of Dalai Lama’s exile in India (1950~2010) into four stages. It summarizes international political and economic situations, foreign policy of China and Tibet government and the involvement of the third parties at different stages. It also observes the interrelations of the above three factors and investigates the background of international involvement of China-Tibet issues. These observations are used as background information to analyze and review the nine times of negotiations between China and Tibet, to probe into the demands of China and Tibetan governments and the international response, to review the third parties’ position and strategies to urge the negotiations and to understand the influence and change of China-Tibet relations. The purpose of the study is to understand the role of state actors as mediator and the reasons of the negotiation deadlock between China and Tibet.
