A democracy activist was detained in Nanjing on Thursday and police told his wife he would be charged with subversion of state power, the AP reported. Guo Quan, who founded the China New Democracy Party last year, has been arrested several times before. Shortly after the Sichuan earthquake he was detained for 10 days after writing articles criticizing the government’s response to the disaster. "I was told it was quite different this time. The police told me to prepare myself psychologically," his wife, Li Jing, said. Guo, an expert on Chinese literature, lost his teaching duties at Nanjing Normal University after launching the China New Democracy Party, which calls for the establishment of multiparty democracy in China.
