Leave it to China to engineer a human rights atrocity. Tibet, Hong Kong and now the Uighurs of Xinjiang province. To those who dare differ with Beijing, you will be assimilated into the collective... resistance is futile.
Most Muslim theocracies have been strangely silent on this with the sole exception of Saudi Arabia, who praised the Chinese initiative as laudable, since apparently Uighurs aren't "Proper" Muslims in the eyes of the Wahhabis.
