China is offering up to 1 million yuan ($160,000) in rewards to "terrorism" informants in its western Xinjiang region, state media said on Tuesday, in the latest policy aimed at getting a handle on unrest there.

Authorities in numerous regions and provinces around China have offered money for tip-offs in recent months after a series of attacks that the government has blamed on separatists and Islamist militants from Xinjiang, home to the Muslim Uighur ethnic minority.

Cities in Xinjiang, where a suicide bombing killed 39 people at a market in the capital Urumqi in May, have offered rewards for tips on everything from "violent terrorism training" to growing long beards as authorities try to root out those they say want to establish an independent state called East Turkestan.
