The Japanese military has reported a series of movements by the People’s Liberation Army (PLA) near the ongoing 'Keen Sword' joint military exercises conducted by Japan and the United States. According to Japanese officials, several Chinese naval vessels—including a supply ship capable of supporting the Liaoning aircraft carrier—have been observed in the vicinity of the drills. Additionally, Japanese forces scrambled fighter jets on Monday after detecting three PLA aircraft, specifically two drones and one reconnaissance plane, flying through international airspace between Japanese islands before returning toward the Chinese mainland.

The 'Keen Sword' exercises are biennial drills designed to test the interoperability of Japanese and American forces. While the Japanese government has characterized the presence of Chinese assets as monitoring activities, the timing of these movements coincides with the drills' focus on potential regional contingencies, specifically regarding Taiwan. The PLA has not issued a formal statement regarding the specific purpose of these deployments, though such maneuvers are often interpreted by military analysts as a response to perceived security threats posed by joint exercises involving foreign powers in the region. The presence of a support vessel for the Liaoning carrier suggests a high level of operational readiness by the Chinese navy during these observations. While the aircraft remained in international airspace, the scramble of Japanese jets highlights the heightened state of alert maintained by Tokyo during these joint maneuvers.
