China and Russia have conducted a joint naval firing drill in waters Tokyo claims as its exclusive economic zone (EEZ). The exercise involved a Chinese Luyang III-class destroyer and a Russian naval vessel operating approximately 180km southwest of Okinotori Island, Japan’s southernmost territory. Japanese officials confirmed the activity, raising concerns about increasing military cooperation between the two nations. This drill marks a recent instance of Sino-Russian joint military exercises, occurring within a region of strategic importance and existing territorial disputes. The location of the exercise near Okinotori Island, claimed by Japan, is particularly sensitive. This latest display of naval coordination likely aims to signal a unified front and demonstrate capabilities in the East China Sea. The Japanese government is analyzing the drill’s implications for regional security.
