Chinese president and commander-in-chief Hu Jintao urged the building of a powerful navy that is prepared "at any time" for military struggle, state media reported on Thursday.

At a meeting of delegates to a Communist Party meeting of the navy on Wednesday, Hu said China, whose military build-up has been a source of friction with the United States, was a major maritime country whose naval capability must be improved.

"We should strive to build a powerful navy that adapts to the needs of our military's historical mission in this new century and at this new stage," he said in comments splashed on the front pages of the party mouthpiece People's Daily and the People's Liberation Army Daily. "We should make sound preparations for military struggles and ensure that the forces can effectively carry out missions at any time," said Hu, pictured in green military garb for the occasion.
