After the Incorporation of Xinjiang into the People's Republic of China under Mao Zedong to establish the PRC in 1949, there have been considerable ethnic tensions arising between the Han Chinese and Turkic Muslim Uyghurs. This manifested itself in the 1997 Ghulja incident, the bloody July 2009 Ürümqi riots, and the 2014 Kunming attack. This has prompted China to suppress the native population and create re-education camps for purported counter-terrorism efforts, which have reportedly fuelled resentment in the region.
