 A Chinese aircraft carrier passed through the Taiwan Strait on Sunday to conduct scientific research tests and routine training in relevant waters of the South China Sea, according to a spokesperson for the People's Liberation Army (PLA) Navy.

The organization of the cross-regional tests and training of the homemade aircraft carrier is a normal arrangement in the process of aircraft carrier construction, is not aimed at any specific target and has nothing to do with the current situation, spokesperson Cheng Dewei said.
