Chinese government censors have launched a sweeping campaign to purge any mention of a corruption investigation in Namibia from the internet because it involves a company formerly run by the son of China's president.
The government's Central Propaganda Department has ordered all Chinese search engines to block any searches related to the case and has also shut down popular social networking sites such as Facebook, YouTube and Twitter.
The crackdown came after African media reported three people had been charged with corruption in connection with a lucrative contract for Nuctech, the airport scanner company controlled by Hu Haifeng, the 38-year-old son of President Hu Jintao.
