The desire for independence or greater political and cultural autonomy largely stems from resentment over perceived restrictions to religious and cultural expression, ethnic conflict with the local Han Chinese population, income inequality, and the perception that Beijing's government is misallocating Xinjiang's natural resource wealth. Some groups have adopted violent tactics in pursuit of these goals, mostly the establishment of a separate Uyghur state called East Turkistan or Uyghuristan, which lays claim to a large part of China. Entities identified in Chinese government documents as having involvement in violent attacks include the East Turkistan Islamic Movement (ETIM), East Turkistan Liberation Organization (ETLO), United Revolutionary Front of East Turkestan (URFET), and the Uyghur Liberation Organization (ULO). Members of these groups are believed to have received training in Central Asian nations such as Afghanistan and Pakistan. Such violent groups has been noted as frequently splintering, merging, and collapsing, which makes claims difficult to substantiate. China's Muslim Hui people, who are comparatively well integrated into Chinese society, regard some Uyghurs as "unpatriotic separatists who give other Chinese Muslims a bad name," according to the New York Times.
