China's first aircraft carrier, the Liaoning, has conducted more than 100 tests and training tasks since early December, when it began a training mission in the South China Sea, the navy said on Sunday.

"The Liaoning successfully performed several tests of the combat system today and organized for the first time comprehensive combat training," the People's Liberation Army navy said in a statement. "Through this operation, we tested the carrier's combat capability and tried the performance of its propulsion and seaworthiness."

This is the first time the Liaoning has made a long-distance training voyage since it was commissioned into the PLA navy last year, the statement said, adding that the mission is characterized by a large number of tests, rigorous standards, complicated circumstances as well as collaboration with multiple military units.
