 According to Martin, Chinese authorities frequently classify any act of violence or separatist activity in Xinjiang as a manifestation of terrorism, while comparable acts by ethnic Han Chinese would not be classified in this manner.On 27 May 2014 a rare mass trial was held at a packed sports stadium in Xinjiang where three people were sentenced to death and another 53 received lengthy jail terms, after being convicted of terrorism charges.39 people had been sentenced at a similar gathering a week previous.
