The Xinjiang conflict is an ongoing separatist conflict in China's far-west province of Xinjiang, whose northern region is known as Dzungaria and whose southern region the Tarim Basin is known as East Turkestan. Uyghur separatists and independence movements claim that the region is not a part of China, but that the Second East Turkestan Republic was illegally incorporated by the PRC in 1949 and has since been under Chinese occupation. The East Turkestan independence movement is led by Turkic Islamist militant organizations, most notably the Turkistan Islamic Party (formerly the East Turkestan Islamic Movement), against the government in Beijing.
