regardless of what you mean, can I just put phrases like: "hysteria about terrorism after the attacks in Xinjiang" into context:
"Rather than embrace lawyers, writers, and whistleblowers as allies in an effort to deal effectively with rising social unrest, the government remains hostile to criticism. The government targets activists and their family members for harassment, arbitrary detention, legally baseless imprisonment, torture, and denial of access to adequate medical treatment. It has also significantly narrowed space for the press and the Internet, further limiting opportunities for citizens to press for much-needed reforms."
Specifically on Xinjiang:
"Following the Urumqi attack, the Chinese government announced a year-long anti-terrorism crackdown in Xinjiang. Within the first month, police arrested 380 suspects and tried more than 300 for terror-related offenses. Authorities also convened thousands of people for the public sentencing of dozens of those tried. In August, authorities executed three Uighurs who were convicted of orchestrating an attack in Beijing’s Tiananmen Square in October 2013. Fair trial rights remain a grave concern given the lack of independent information about the cases, the government’s insistence on expedited procedures, the fact that terror suspects can be held without legal counsel for months under Chinese law, and China’s record of police torture.
While there is reason for the government’s concern with violence, discriminatory and repressive minority policies only exacerbate the problem. In January, police took into custody Ilham Tohti, a Uyghur professor at Beijing’s Minzu University critical of the Chinese government’s Xinjiang policy. Tohti remains detained and is charged with “separatism,” which can result in life imprisonment. In August, Uighur linguist Abduweli Ayup was given an 18-month sentence for “illegal fundraising” after trying to raise money for Uighur-language schools."
