The 14th Dalai Lama Tenzin Gyatso, is both the head of state and the spiritual leader of Tibet. In 1950 the Dalai Lama was called upon to assume full political power after China's invasion of Tibet in 1949. In 1954, he went to Beijing for peace talks with Mao Zedong and other Chinese leaders, including Deng Xiaoping and Chou Enlai. Since the Chinese invasion of Tibet, the Dalai Lama has appealed to the United Nations on the question of Tibet. The General Assembly adopted three resolutions on Tibet in 1959, 1961 and 1965. In September 1987 the Dalai Lama proposed the Five Point Peace Plan for Tibet as the first step towards a peaceful solution to the worsening situation in Tibet. In 1989 he was awarded the Nobel Peace Prize for his non-violent struggle for the liberation of Tibet. He has consistently advocated policies of non-violence, even in the face of extreme aggression. He also became the first Nobel Laureate to be recognized for his concern for global environmental problems.
