In the first half of this month, various moves by China occurred in the areas surrounding Japan. In addition, the deterioration of Japan–China relations continued to advance.

On December 6, in the area southeast of Okinawajima Island, two incidents occurred in which Chinese carrier-based fighter aircraft intermittently directed radar at Japan Air Self-Defense Force (JASDF) F-15s while they were scrambled. On December 9, Chinese and Russian bombers that had joined forces over the East China Sea advanced to the Pacific Ocean off the coast of Shikoku and conducted a long-range joint flight. During this period, China has widely carried out external activities to restrain and condemn Japan, citing the outcomes of World War II and related issues.

In response, Japan lodged a strong protest over Chinese military aircraft directing radar at Japanese aircraft and conveyed serious concerns to both China and Russia regarding their joint bomber flights. In addition, Japan refuted China’s claims and explained its position to the international community.

Additionally, reports cited a U.S. think tank’s finding that China is strengthening its intelligence and reconnaissance capabilities and enhancing its strike capabilities at outposts it occupies in disputed areas of the South China Sea, including the construction of new facilities and structures.
