China has accused Japanese warplanes and ships of conducting multiple surveillance operations and "provocations" during a recent deployment of its Liaoning aircraft carrier group to the western Pacific.
State broadcaster CCTV aired footage of the encounters, showing Chinese forces warning off Japanese assets during live-fire exercises.
The incident underscores the intensifying military presence in the region, where Beijing is expanding its naval footprint.
The drills come as China continues to assert its role in global energy markets, particularly amid ongoing disruptions in the Strait of Hormuz.
Beijing has previously framed its engagement in energy and fertilizer sectors as a stabilizing force during the crisis.
Tensions between China and Japan have been rising, with both nations increasing military activities in contested waters.
