Upgrade of arms won't alter policy

BEIJING - The modernization of China's armed forces will not alter the nation's defensive policy, and China's naval strategy will remain based on offshore defense, the Ministry of National Defense said on Wednesday.

China's first aircraft carrier has finished its first sea trial, which proceeded "as expected", ministry spokesman Yang Yujun said at a regular news conference.

"Commissioning an aircraft carrier is a long and complicated project. In this process, there will be a number of tests," Yang said, adding that the carrier is currently undergoing refitting and further tests.
