Shi Tao, a Chinese reporter jailed after being convicted of leaking state secrets, is participating in a US lawsuit that accuses internet company Yahoo of helping the Chinese government target dissidents. According to Shi's mother, the journalist wants compensation from Yahoo for its alleged part in providing information that led to his arrest. Shi, who used to write for financial publication Contemporary Business News, received a 10-year jail sentence in 2005, the Wall Street Journal reported. His conviction was partly based on an email he sent containing information on a government circular concerning media restrictions. Yahoo has admitting passing data to the Chinese government and argues that, had it not done so, company employees could have faced prosecution for ignoring local laws. Other plaintiffs listed in the World Organization for Human Rights USA case include Wang Xiaoning, who was sentenced in September 2003 for "incitement to subvert state power". He is said to have distributed pro-democracy writings by himself and others by email and through Yahoo's mail group system.
