A Chinese Luyang III-class destroyer fired live rounds 180 km southwest of Okinotori, Japan's southernmost island, during China-Russia joint naval operations. Tokyo protested the potential safety risk while noting the action did not violate international law.
Imagine two kids sharing a giant sandbox. One kid started shooting a toy cannon really far away but still inside the sandbox. The other kid complained it was too close, even though nobody got hurt. The grown-ups are now arguing about where the sandbox actually ends.

A Drill Inside a Contested EEZ
The Japanese Joint Staff revealed that a Chinese Luyang III-class guided-missile destroyer conducted a live-fire exercise roughly 180 kilometers southwest of Okinotori, Japan's southernmost island, on a Sunday in mid-July. The drill took place within waters that Tokyo considers its Exclusive Economic Zone, an area where Japan holds rights over natural resources but where, under UNCLOS Article 58, foreign military activity is generally permitted so long as safety warnings are issued. China's warships did broadcast a notice to vessels in the area shortly before firing, which is why the Joint Staff concluded the action did not breach international law even as it raised alarm bells in Tokyo. Chief Cabinet Secretary Minoru Kihara said the government had conveyed its concerns about the safety threat, framing the episode as part of a broader pattern of Chinese and Russian operations around Japan.
The China-Russia Axis Around Japan
The live-fire drill was not a solo Chinese maneuver. The destroyer was operating with two other Chinese warships and a Russian frigate as part of joint China-Russia naval activity in the Pacific, exercises that Beijing officially wrapped up on July 13. Defense Minister Shinjiro Koizumi, speaking in Britain, used the episode to underscore what he described as the deepening military cooperation between Beijing and Moscow, citing alongside it a recent Chinese submarine-launched ballistic missile test and at least 10 joint Chinese-Russian bomber flights around Japan. The cumulative picture is one of an increasingly synchronized two-power operational tempo in waters that Japan considers its strategic backyard, from the Okinawa-Miyako corridor to the seas south of Okinotori. Tokyo's response — public protest paired with pledges to continue surveillance — signals that this is being tracked as a sustained trend rather than a one-off.
Okinotori: Island, Atoll, and Legal Fault Line
Underpinning the dispute is a long-running disagreement over the status of Okinotori itself. Japan classifies the feature as an island and therefore claims a full EEZ around it, while China argues it is merely an atoll and generates no such zone. The article notes that China's official Xinhua account placed the live-fire exercises off the port city of Qingdao on China's east coast, a location far from Okinotori, while Tokyo's account places them 180 kilometers southwest of the feature. That mismatch is not incidental; the location of the firing is precisely what determines whether the exercise occurred inside a zone Japan claims as its own. With both sides staking out incompatible narratives and Beijing rejecting what it calls groundless speculation, Okinotori is likely to remain a recurring flashpoint whenever Chinese or Russian naval activity drifts into the western Pacific.
Key points
- A Chinese Luyang III-class destroyer fired live rounds 180 km southwest of Okinotori inside Japan's claimed EEZ, alongside two other Chinese warships and a Russian frigate.
- Japan's Joint Staff said the action did not violate international law because China issued a safety warning to nearby vessels, but Tokyo formally protested the potential safety risk.
- Defense Minister Shinjiro Koizumi used the incident to highlight deepening China-Russia military cooperation, alongside recent submarine-launched missile tests and joint bomber flights around Japan.
- China disputes Japan's EEZ claim around Okinotori, calling it an atoll rather than an island, and its official account placed the exercises off Qingdao rather than near the feature.
- It is the first time Japan has publicly disclosed detection of Chinese live-fire drills inside its EEZ.
If the episode remains a one-off public disclosure without further escalatory moves, the diplomatic protest may serve its purpose: Tokyo signals vigilance, Beijing registers the cost to its reputation, and both sides continue the routine of EEZ cat-and-mouse without a deeper rupture. The fact that Japan's Joint Staff itself said the action did not violate international law leaves room for the incident to be absorbed without a crisis.
If live-fire drills inside Japan's claimed EEZ become a recurring tactic, or if future exercises omit the safety warnings that protected China from a legal violation this time, the incident could mark the first step in a gradual normalization of more assertive Chinese behavior around Okinotori and the broader Okinawa-Miyako corridor. Coupled with deepening China-Russia bomber patrols and submarine-launched missile tests, the cumulative trajectory risks hardening Tokyo's threat perceptions and accelerating Japanese defense build-up in ways that further entrench regional military rivalry.
