China is denying claims aired by the UN Committee on the Elimination of Racial Discrimination that up to a million Muslim Uighurs have been detained in "re-education camps" in Xinjiang region. But Beijing appears to be imposing harsh surveillance and restrictions on freedom of worship on Muslims throughout China, even requiring those making the pilgrimage to Mecca to be fitted with GPS tracking devices. Yet such methods almost always prove counter-productive, leading to resentment that only fuels the unrest that Chinese authorities are responding to. This week saw mass protests in Weizhou, Ningxia province, after authorities attempted to demolish a newly built mosque which they said had not received construction permits. After days of protest, authorities backed down and agreed to postpone the demolition. (Photo of protest at Weizhou Grand Mosque from Weibo via BBC News)
