China's second aircraft carrier, which is now under construction, will focus on military operations rather than training and technological experiments, according to a senior military researcher.

"This carrier will have different missions than those for the Liaoning (the country's first aircraft carrier)," Senior Captain Zhang Junshe with the People's Liberation Army Naval Military Studies Research Institute told the official PLA Daily on Friday.

"We use the Liaoning to test the reliability and compatibility of systems on carriers, and to train personnel. The second carrier will mainly do what a genuine aircraft carrier is supposed to do: running combat patrols and delivering humanitarian aid."
