Chinese and Russian Live‑Fire Drill in Disputed EEZ Tests Japan’s Maritime Nerve
Chinese warships, joined by a Russian vessel, have conducted a live‑fire drill inside waters near Okinotori Island that Japan claims as its exclusive economic zone, prompting a formal protest from Tokyo. Japan concedes the exercise was legal under international law but calls it a navigation risk and another challenge to its maritime claims. The article unpacks the legal gray zone, the signal from Beijing and Moscow, and what it means for regional naval dynamics.
A live‑fire exercise by Chinese and Russian ships near a tiny atoll has given Japan a fresh reminder that its far‑flung maritime claims are under pressure not only in courtrooms and conference halls, but on the water itself. Tokyo has protested after Chinese warships, joined by a Russian vessel, conducted shooting drills inside waters near Okinotori that Japan treats as part of its exclusive economic zone.
Japan’s government acknowledges that the exercise itself appears legal under international law, which allows foreign naval vessels to conduct military activities in another state’s EEZ. But officials have condemned the drill as a navigation risk and a deliberate challenge in an area where China contests Japan’s entitlement to an EEZ at all. The protest reflects less a legal dispute over live‑fire rights than a political struggle over who sets the rules in a strategic stretch of the western Pacific.
For Japanese mariners and nearby shipping, the immediate concern is practical: live‑fire drills with large‑caliber weapons add danger to already busy sea lanes. Navies typically issue warnings and set temporary danger zones, but miscommunication or miscalculation at sea can have consequences that lawyers must sort out only after the fact. Every time Chinese and Russian vessels practice together near Japanese‑claimed waters, civilian crews must adjust routes and timings to avoid finding themselves on the wrong side of an exclusion line.
Okinotori, a remote outcrop south of Japan’s main islands, has outsized strategic importance. Tokyo maintains that the feature qualifies as an island under the UN Convention on the Law of the Sea, generating a 200‑nautical‑mile EEZ rich in potential resources and strategic depth. Beijing rejects that claim, arguing that Okinotori is at most a rock that cannot sustain human habitation, and so cannot project such zones. When Chinese and Russian ships conduct joint drills there, they are effectively performing naval diplomacy in steel: asserting that Japan’s legal position does not control what happens on the water.
For China, the exercise fits a broader pattern of pushing back against what it sees as Japanese and U.S. efforts to contain its navy. Operating with a Russian vessel underscores an emerging, if uneven, convergence between Beijing and Moscow at sea, from the Sea of Japan to the western Pacific approaches. For Russia, whose Pacific Fleet has been relatively quieter than its forces elsewhere, the chance to drill alongside China near a contested Japanese EEZ is a low‑cost way to signal that its reach extends beyond Ukraine.
Japan’s discomfort is not just about this one drill. Tokyo faces overlapping maritime challenges: regular Chinese coast guard and militia activity around the Senkaku/Diaoyu Islands in the East China Sea, North Korean missile launches that splash down in its EEZ, and now combined Chinese‑Russian exercises near Okinotori. Each incident tests the credibility of Japan’s ability to monitor, respond and coordinate with allies in a maritime environment that is becoming more crowded and contested.
One sentence crystallizes the stakes: for Japan, the issue is less the shells splashing in the water than the precedent they set for who gets to treat its claimed zones as military training grounds. If joint Chinese‑Russian drills in these waters become routine, it could normalize patterns of presence that erode the political weight of Japan’s claims, even if the underlying legal arguments remain unchanged.
The next indicators to watch are whether Beijing or Moscow schedule further exercises near Okinotori or other sensitive areas, how Japan adjusts its own patrol and training patterns in response, and whether Tokyo raises the issue in multilateral forums or deepens operational coordination with the United States and other partners. A single drill will not redefine the balance of power in the Pacific, but a steady rhythm of such operations could reshape how seriously others take Japan’s maritime red lines.
