As of June 1, residents of the Yili Kazakh Autonomous Prefecture in China's far northwest must give police DNA samples, fingerprints, voiceprints and a "three-dimensional image" in order to apply for certain travel documents, the official Yili Daily said, citing the local public security bureau.
Many members of the mostly Muslim Uighur community in Xinjiang complain of discrimination -- including denials of passport applications -- as well as controls on their culture and religion.
Those who fail to fulfil requirements will be refused documents, it added.
Yili prefecture borders Mongolia, Russia and Kazakhstan. It is part of Xinjiang, homeland of the more than 10 million-strong Uighur minority.
