Chinese carrier holds air drills as Tokyo, Beijing trade barbs

On the weekend, China's Liaoning aircraft carrier conducted about 100 take-offs and landings as it sailed east into the Pacific Ocean past the Okinawa Islands, Japan's Self-Defense Forces said on Monday.

Tokyo summoned China's ambassador, Wu Jianghao, on Sunday to protest behaviour it called dangerous and regrettable after the carrier's fighter jets aimed radar beams at its aircraft scrambled to shadow the vessel the previous day.
