During the Ili Rebellion the Soviet Union backed Uyghur separatists to form the Second East Turkistan Republic (2nd ETR) in Ili region while the majority of Xinjiang was under Republic of China Kuomintang control. The People's Liberation Army entered Xinjiang in 1949 and the Kuomintang commander Tao Zhiyue surrendered the province to them. The original provincial government was relocated to Taipei as the Sinkiang Provincial Government Office (新疆省政府辦事處) to symbolize the ROC's claim of sovereignty over the province; it was eventually dissolved in 1992.
