Chinese authorities have <A HREF="http://news.yahoo.com/s/ap/20051103/ap_on_hi_te/china_blocked_blog">blocked a pro-democracy Weblog</A> after it was nominated for a freedom of expression award by a German radio station, a press freedom group said Thursday. The blog, titled Wang Yi's Microphone, dealt with "sensitive subjects" and was maintained by a teacher from Sichuan province. China's communist government encourages Internet use for education and business, but blocks material deemed subversive or pornographic. Dissidents have been arrested under vaguely worded national security laws for posting items critical of the government. One of Wang's most recent posts dealt with a campaign by peasants in the southeastern province of Guangdong to remove a village chief accused of corruption.
