China has accused Japanese warplanes and ships of carrying out multiple “provocations” and surveillance operations during a carrier group’s deployment to the western Pacific for live-fire exercises.

State broadcaster CCTV released a video on Monday showing at least four “close-range” encounters, and said the Liaoning carrier group had “warned off” the warships and surveillance planes.

It included footage of Japanese warships as well as clips of aircraft, at least one of which appeared to have been taken in the air.

Beijing has not disclosed the specific locations and dates of these encounters. Japan has not yet responded to the accusations.

CCTV said the carrier strike group returned to its home port of Qingdao on Monday after completing a 40-day long-range combat training exercise in areas including the South China Sea and western Pacific.

“During the training exercise, Japanese ships and aircraft repeatedly tracked, monitored, harassed and provoked the Chinese at close range,” CCTV said.
