Yahoo 'helped jail China writer'

Internet giant Yahoo has been accused of supplying information to China which led to the jailing of a journalist for "divulging state secrets".
Reporters Without Borders said Yahoo's Hong Kong arm helped China link Shi Tao's e-mail account and computer to a message containing the information.
Shi Tao, 37, worked for the Contemporary Business News in Hunan province, before he was arrested and sentenced in April to 10 years in prison.
According to a translation of his conviction, reproduced by Reporters Without Borders, he was found guilty of sending foreign-based websites the text of an internal Communist Party message.
"We already knew that Yahoo! collaborates enthusiastically with the Chinese regime in questions of censorship, and now we know it is a Chinese police informant as well," Reporters Without Borders said in a statement.
The companies say they have to abide by local regulations, and point out that since China is set to be the world's biggest internet market, they cannot ignore it.
