China's national defence ministry had said the Liaoning, named after a northeastern Chinese province, was part of a flotilla on a "routine training mission" and would make a port of call in the former British colony. / AFP PHOTO / Anthony WALLACE        (Photo credit should read ANTHONY WALLACE/AFP via Getty Images)
