Uighur Splittists?
Where will it all end?
Like Tibetans in Tibet, Uighurs have historically been the predominant ethnic group in Xinjiang, which is officially known as the Xinjiang Uighur Autonomous Region. In both Tibet and Xinjiang, indigenous groups have chafed at the arrival of large numbers Han Chinese, the country’s predominant ethnic groups, who have migrated to western regions with strong government support.
Uighurs, like Tibetans, have complained that recent Han arrivals now dominate their local economies, even as the Han-run local governments insert themselves deeper into schools and religious practices to weed out cultural practices that officials fear might reinforce a separate ethnic or religious identity. In telephone interviews, Han residents of Khotan and nearby areas said there was a long history of distrust and tension between Han and Uighur communities. Some Han migrants insisted the atmosphere remained volatile, and said that the Uighurs had been inspired by the recent Tibetan unrest.
Since you ask, the Uighurs actually speak a Turkic language, which means that they have even less to do with the Chinese than the Tibetans, who at least once probably spoke the same language (a few thousands years ago, that is).
