The Chinese navy is using its first aircraft carrier, the Liaoning, for training and testing and will decide the future development of the aircraft carrier after a few years of evaluation, Admiral Wu Shengli said on Thursday.

The commander-in-chief of the People's Liberation Army navy, on a visit at the invitation of his US counterpart, told reporters at the Washington Navy Yard that Chinese sailors would carry out "very heavy" training over the next two or three years as they assess the carrier.

"After the training and experimentation we will have a final evaluation on the development of the aircraft carrier for the PLA navy," said Wu, whose delegation included the commander of the Liaoning and the first pilot to land on its flight deck.
