The wife of Chinese dissident has come to the US to sue Yahoo for turning over her husband's emails to Chinese authorities. He was sentenced in 2003 to 10 years in prison for publishing "subversive" articles on the Internet, reports Voice of America.

Speaking with VOA's Mandarin Service Wednesday after arriving in Washington, Yu Ling said Chinese police arrested her husband, Wang Xiaoning, partly because Yahoo's Hong Kong office gave Chinese authorities information about his e-mail accounts.

Yu Ling said she has come to the United States to sue the company for damages and to demand an apology.

Last year, Yahoo provided the Chinese with information about Shi Tao, a journalist who emailed to Western news outlets details of China's plans to handle the 15th anniversary of Tiananmen Square.
