I did not know that such a riot occurred recently in China. Thanks for letting me know.
I am not sure if it could be classified as a 'riot' but needless to say they weren't happy.

The Uygurs, as with most believing Muslims, were subjected to forced labor in the 30,000 communes set up in the predominantly Muslim provinces. The imams and akhunds were singled out for humiliating punishments and tortures....and were forced to tend to pig farms, which were sometimes kept in government-closed mosques. Under the pretext of unification of national education, Islamic schools were closed and their students transferred to other schools which taught only Marxism and Maoism. Other outrages included the closing of over 29,000 mosques, the widespread torture of imams, and executions of over 360,000 Muslims. Since the death of Mao and the end of his hard-line Marxist outlook nearly fifteen years ago, the communist government has greatly liberalized its policies toward Islam and Muslims. And despite the horrors of the Cultural Revolution, Islam has continued to thrive in China.
