The capital of China’s Xinjiang region, home to the mostly Muslim Uighur minority, has launched a campaign against halal products to stop Islam penetrating secular life and fuelling “extremism”.

In a meeting on Monday, the Communist Party leaders of Urumqi led cadres to swear an oath to “fight a decisive battle against ‘pan-halalization’,” according to a notice posed on the city’s official WeChat account.Everyday halal products, like food and toothpaste, must be produced according to Islamic law.China has been subject to heavy criticism from rights groups and foreign governments amid reports of a punitive crackdown that has seen the detention of as many as 1 million mostly Muslim ethnic Uighurs in Xinjiang.Beijing has denied it is systematically violating the rights of Xinjiang’s Muslims, saying it is only cracking down on extremism and “splittism” in the region.
