Beijing (AP) China is continuing efforts to quell violence and unrest well ahead of the august opening of the Beijing Olympics.
More than 1,000 people are under arrest or turned themselves in to police after last month's deadly violence in the capital of Tibet. Trials will be held before May 1st.
Rioting last month marked the biggest anti-government protests in Tibet and across western China in almost two decades.
Meantime, international criticism is mounting over china's sentencing today of a civil rights activist to more than three years in prison for subversion.
Hu Jia has been involved in aids awareness and environmental rights. He's been under house arrest. Charges stem from internet articles he'd written.
