Abstract: After regaining control over Tibet，the Qing dynasty had implemented several measures including conferring titles to the political and religious heads of Tibet, establishing the administrative system，appointing officials，stationing troops，reassuring Dalai Lama and Panchen Lama to be the leaders of both the secular government and the Tibetan Buddhist religion，and finally building up a theocracy system called “Gaxag”. Those efforts allowed the Qing government to rule Tibet effectively and maintain its sovereignty and territorial integrity and significantly influenced the Tibet policy of later ages. This essay reviews the Qing dynasty's Tibet policy from an anti-secessionism perspective and suggests that those policies ignored the economic and culture factors.The weak economic-culture connection between Tibet and inland China potentially caused a Tibet secessionism in the early twentieth century.
