BEIJING (AP) -- Officials and state media say 21 people have been confirmed dead in a tugboat capsizing in eastern China after the vessel was lifted to the surface and dragged to shallow waters of the Yangtze River.

The state-run Xinhua News Agency said Saturday that one person remains missing from Thursday's trip to test the newly built tugboat in the river's Fubei Channel in the eastern province of Jiangsu.

The ship's owner, parts suppliers and engineers were among 25 people aboard for the test, including eight foreigners: Four Singaporeans, an Indian, an Indonesian, a Japanese and a Malaysian.

Three people were rescued, all Chinese. Officials did not immediately give the missing person's nationality.

A Jiangsu search and rescue center official, who declined to give his name, confirmed that 21 people were dead. (AP)
