Oh, those silly Chinese. The Beijing Olympics are a few weeks away, and muckrakers, gays and other 'undesirables' in China have faced persecution in recent months, all likely stemming from an effort by Chinese authorities to put on a good face for the world. AIDS activist Wan Yanhai has been repeatedly followed by police and plans to leave the country in August. Dechen Pemba, an Tibetan with a British passport and a Chinese work visa was picked up by police outside her apartment, taken to the airport and put on a plane to London. And Lu Jun, a campaigner for the rights of Chinese people with Hepatitis B, has seen his website taken down and was detained by authorities when he arrived back in the country after attending a Hep B conference in Los Angeles.
