According to reports by Human Rights Watch and others, in China, psychiatric abuse is shockingly common against dissidents, who are jailed and silenced under the guise of psychiatric treatment. In one well-known case, Wang Wanxing was held in an Ankang for 13 years, for staging a brief, one-man pro-democracy protest on Tiananmen Square on the third anniversary of the massacre there. He was released unexpectedly in 2005 and sent to Germany, where he was evaluated by a team of psychiatric experts, who found no mental disorder. Wang told Human Rights Watch about the conditions he had endured. He stated, for example, that he had been forced to watch staff members administer “electric acupuncture treatments” in which the current used was excruciating. One inmate died of a heart attack during such a “treatment.”
