The Urumqi People's Intermediate Court convicted Ilham Tohti after a heavily guarded two-day trial that ended last week, said lawyer Liu Xiaoyuan, who heard the news from the scholar's family. The court didn't answer several telephone calls today seeking information about the trial.
Liu said the court also ordered the confiscation of all of Ilham Tohti's possessions. In a message posted on Twitter, the lawyer said Ilham Tohti told the court he did not agree with the verdict.
Chinese authorities detained him in January along with seven of his students.
Tensions have run high and flared into violence in the Xinjiang region where many of China's Uighurs live. Authorities said several explosions killed two people Sunday in central Xinjiang but did not say who carried out the attack.
William Nee, a Hong Kong-based researcher with the human rights group Amnesty International, said today's conviction shows the Chinese government is cracking down on any criticism of its Uighur policies in Xinjiang. After the recent violence, authorities have prohibited people in the region from having beards or wearing veils, and locals say many have been detained for speaking out about the situation there.
"It'll send a strong signal to (Uighur scholars) there's not much to be gained to take some risks and personal initiative to bridge the gap between what obviously people on the ground are feeling, severe discontent with the way things are going, and explaining them to Han policymakers," Nee said.
