BEIJING (AP) -- A teacher in southwest China has been jailed for two years for posting a note saying "Down with the Communist Party" on an online bulletin board, a jail official said Monday.
Jiang Shihua, 27, was sentenced in December on subversion charges and is being held in Nanchong, a city in Sichuan province, the duty officer at the detention center said. The officer, contacted by phone, would give only his surname, Xu.
The case adds to a growing Chinese crackdown on dissent in cyberspace. Beijing is eager to harness the Web for economic development while blocking the spread of criticism of communist rule.
An entrepreneur was put on trial in February for subversion after articles commemorating the 1989 pro-democracy movement were posted on his Web site. The case against Huang Qi, also in Sichuan province, is still under way.
Jiang was arrested in August on subversion charges after he joined an online discussion that criticized corruption, the Hong Kong-based Information Center for Human Rights and Democracy said.
Jiang's message included the phrase, "I just want to say: Down with the Communist Party," according to the Information Center. Jiang is appealing, Xu said.
Jiang taught electronics at Nanchong High School. After his arrest, Nanchong schools were ordered in December to start an ideological training campaign for teachers and other employees, said a school spokeswoman who refused to be identified.
