Comparison of United States incarceration rate with other countries
The incarceration rate of the People's Republic of China varies depending on sources and measures. According to the World Prison Brief, the rate for only sentenced prisoners is 118 per 100,000 (as of 2015). The rate for prisoners including estimations for the number of pre-trial detainees and those in administrative detention is 164 per 100,000 (as of 2015). In a 2010 interview Harry Wu, a U.S.-based human rights activist and ex-Chinese labor camp prisoner, estimates that "in the last 60 years, more than 40–50 million people" were in Chinese labor camps, but that period includes the mass incarcerations of the 1950s or the Cultural Revolution (1966-1976) and is not representative of modern China.

The Chinese government's response brought attention to the risks of using Twitter for controversial political issues, as well as criticism from human rights and open technology groups. “Sentencing someone to a year in a labor camp, without trial, for simply repeating another person’s clearly satirical observation on Twitter demonstrates the level of China’s repression of online expression,” said Sam Zarifi, Amnesty International’s Director for the Asia-Pacific. The organization further commented, "Cheng may be the first Chinese citizen to become a prisoner of conscience on the basis of a single tweet." Twitter CEO Dick Costolo posted to his Twitter account, "Dear Chinese Government, year-long detentions for sending a sarcastic tweet are neither the way forward nor the future of your great people."
