More than 200 people will be prosecuted on charges of involvement in the Xinjiang disturbances of last month, BBC reported according to the China Daily.
The trials are expected to start this week in Urumqi.
Charges include vandalising public property and transport, organising crowds to cause bodily harm to others, robbery, murder and arson.
Chinese police detained more than 1,500 people after violence between ethnic Uighurs and Han Chinese left 200 dead.
The China Daily that most of the arrests were made in Urumqi and Kashgar, a southern Xinjiang city with a heavy concentration of Uighur people.
The newspaper did not give a breakdown on how many Uighurs and how many Han would go on trial, but it said more than 170 Uighurs and 20 Han lawyers had been assigned to the suspects.
The newspaper reported last week that more than 3,300 items of physical evidence had been collected, including bricks and clubs stained with blood.
The evidence included 91 video clips and 2,169 photographs, it said.
Although security in Urumqi is already high, "a drastic increase in security is expected in the whole city," the newspaper said, especially around the Urumqi Intermediate People's Court.
Armed police are already conducting around-the-clock patrols in the area.
The riots broke out July 5 after police stopped an initially peaceful protest by Uighur youths, apparently prompted by an earlier riot in a factory in southern China.
The government has insisted the violence which followed was engineered by Uighurs in exile, led by Rebiya Kadeer.
It has been pursuing vigorous diplomatic complaints against countries such as Australia and Japan which gave visas for Ms Kadeer to enter and speak.
Many Uighurs want more autonomy, and respect for their culture and religion - Islam - than is allowed by China's strict centrist rule.
The violence in Xinjiang was the worst ethnic unrest in China for decades.
The government says 197 people died in the ensuing violence, and more than 1,700 were injured.
The government says most of the dead were Han Chinese, but the World Uighur Congress claims many Uighurs also were killed.
