A senior regional official on Tuesday reported that officials of China’s ruling Communist Party are partly responsible for a rise in attacks in Xinjiang.
The region’s top anti-bribery official, Xu Hairong, claimed that some party members have taken part in separatist agitation.
"Some communist cadres... even support or take part in violent terrorist attacks," Xu said in the state-run China Discipline Inspection News. Some officials were "wavering on the big issues of opposing anti-separatism and maintaining ethnic unity," he added.
Xinjiang is home to China’s Muslim Uighur population which complains of discrimination and China’s assimilationist policies.
China’s government says it is dealing with a serious threat from separatists in Xinjiang, where many people have been killed in unrest in recent years.
Xu said in a statement that some party officials disapprove of procedures laid out by the higher levels of the Communist Party hierarchy.
"Some waver on clear cut issues of opposing ethnic division and safeguarding ethnic and national unity, and even support participating in violent terrorist acts," Xu said.
A militant group affiliated with Al Qaeda on Nov 20 claimed responsibility for killing at least 27 people and three senior executives of a state-owned Chinese company at a Radisson Blu hotel in Mali's capital Bamako.
Turkey has strong cultural ties with the Uighurs living in the Xinjiang autonomous region, which is called "East Turkestan" by the Uighurs themselves and has a 45 percent Uighur population while ethnic Chinese make up almost 40 percent of the region’s total population.
The Uighurs are subjected to discrimination in many respects including being prevented from practising their faith openly, the banning of beards and headscarves, and being prevented from teaching their children the Quran. Officials and people younger than 18 are banned from participating in religious activities.
