China has insisted there is no "arbitrary detention" and there are no "re-education centres" in its western Xinjiang region, rejecting concerns raised by a UN human rights committee that more than 1 million ethnic Uighurs may be being held in camps.
A committee member last week cited estimates that more than 1 million people in China from the country's Uighur and other Muslim minorities are being held in "counter-extremism centres" and another 2 million have been forced into "re-education camps".
In joint editorials in its Chinese and English versions, the widely read Global Times said the increased security was necessary to avoid the region becoming another Syria, adding criticism of the rights record in Xinjiang was aimed at stirring trouble there and destroying hard-earned stability.
But monitoring groups maintained Uighurs had been targeted in a surveillance and security campaign.
Gay McDougall, a member of the UN Committee on the Elimination of Racial Discrimination, cited estimates 2 million Uighurs and Muslim minorities were forced into "political camps for indoctrination" in the western Xinjiang autonomous region.
