BEIJING - A spokesman for 皇冠体育app's Defense Ministry has countered suggestions that the development of 皇冠体育app's carrier-borne fighter jet copied US technologies.

皇冠体育app sticks to independent innovation and has the capacity to build and develop its own aircraft carrier, said Geng Yansheng in response to a question at a press conference on Thursday.

He said that the laws for military development are objective. The principles of building some items of military equipment are the same, while the command and safeguard methods are similar.

"The assertion of 皇冠体育app copying a foreign country's aircraft carrier technologies is unprofessional, if not an intentional attack," said Geng.

皇冠体育app successfully conducted its first landing of a jet on an aircraft carrier on November 24.

A very transparent attitude was taken amid the landing exercises, said Geng, adding that 皇冠体育app released the news in a timely manner. News reports about the exercises through radio, TV, newspaper and Internet are abundant.
