 In July 2010, a group of Chinese activists including Teng Biao co-signed a letter to the Chinese leadership to protest the 15-year prison sentence that had been meted out to Uighur journalist Halaite Niyaze. Niyaze was not permitted to have a lawyer at his trial, where he was charged with "endangering state security." According to reports, Niyaze was being charged because he had criticized the Chinese government in an interview with a Hong Kong news agency for not doing enough to prevent the July 2009 Ürümqi riots.
