二十世纪四十年代美国的西藏政策发生了历史性的变化。面对东西方冷战与中华人民共和国的建立,美国抛弃了百年来所认同的“西藏是中国领土一部分”的传统立场,力图利用西藏分裂势力阻挠中国新生政权的国家统一与发展进程,对日后几十年中美关系的发展产生了深远影响。 The historic change of the U.S. Tibet policy in the 1940s has taken place. In the face of the Cold War between the East and the West and the establishment of the People’s Republic of China, the United States has abandoned its traditional position of “Tibet is part of China’s territory” for centuries and tried to use the secession forces in Tibet to obstruct the process of national unification and development of the newborn regime in China. The development of Sino-U.S. Relations over the past decade has had a profound impact.
