China's northwestern region of Xinjiang has revised legislation to allow the detention of suspected extremists in "education and training centers."
The revisions published Tuesday come amid rising international concern over a harsh crackdown in Xinjiang that has led to as many as 1 million of China's Uighurs and other Muslim minorities being held in internment camps.
Chinese authorities deny the internment camps exist but say petty criminals are sent to vocational "training centers." Former detainees in the camps say they were forced to denounce Islam and profess loyalty to the ruling Communist Party.
China has come under increasing pressure from the U.S. and the European Union after a United Nations panel confronted Chinese diplomats in August over reports of arbitrary mass detentions and harsh security measures aimed at Muslims.
