US-Japan Keen Sword Exercise Begins as Chinese Military Conducts Drills Across Four Seas

The United States and Japan have commenced the joint military exercise Keen Sword across multiple regions including Okinawa, Kyushu, and Hokkaido, featuring Japan's recently deployed Type 25 surface-to-ship missiles. Concurrently, Chinese forces have launched live-fire and amphibious training drills across the Bohai Sea, Yellow Sea, East China Sea, and South China Sea, including an exercise scheduled to run for 47 days in the southern Yellow Sea. Specific operational interactions between the two military drills have not been reported.
