A Chinese warship fired live rounds inside Japan's exclusive economic zone (EEZ) for the first time, escalating regional tensions and marking a significant shift in military posturing. The incident occurred on Sunday, when a Chinese missile destroyer conducted live-fire drills approximately 180 kilometers from Okinotori, Japan's southernmost island. This development comes amid rising frictions between Beijing and Tokyo over territorial claims and military activities in the region.
Details of the Live-Fire Drill
Three Chinese warships and a Russian frigate were first spotted sailing between Okinawa's main island and Miyako island into the Pacific on Thursday. By early Sunday, the Chinese missile destroyer was located around 330 kilometers southwest of Okinotori. It then issued a warning to nearby shipping about its planned drill, which reportedly included machine guns using live ammunition. Japan's defense ministry acknowledged this as the first time a foreign navy vessel has fired live rounds inside its EEZ.

Japan's Response and Diplomatic Channels
Tokyo responded by mobilizing air and sea surveillance assets and contacting Beijing through diplomatic channels. Japan's top government spokesman, Minoru Kihara, stated that the drill "could have endangered the navigation of nearby ships." He added that Japan would continue to monitor Chinese and Russian vessel activities in the waters around its country with concern. The incident underscores the growing cooperation between China and Russia in military exercises near Japan.
Disputed Status of Okinotori
At the heart of the dispute is the status of Okinotori. Japan considers Okinotori an island, which allows it to claim an exclusive economic zone extending 200 nautical miles. However, Beijing maintains that Okinotori is merely a reef and therefore not entitled to an EEZ. This difference in interpretation gives China legal justification for its military operations in the area. A Chinese aircraft carrier and research ship had previously entered these waters in 2025, but this live-fire drill marks a heightened level of provocation.
Comparison of Chinese and Japanese Positions
| Aspect | China's Position | Japan's Position |
|---|---|---|
| Status of Okinotori | Reef, no EEZ rights | Island, full EEZ rights |
| Legality of drill | Lawful exercise in international waters | Violation of Japanese sovereign rights |
| Military activity | Routine training | Dangerous escalation |
| Diplomatic response | Defends right to operate | Filed protest, increased surveillance |
Broader Geopolitical Implications
This incident is part of a wider pattern of Chinese and Russian military exercises around Japan since Tokyo's relations with Moscow soured over the war in Ukraine and a diplomatic row erupted with Beijing over comments by Japanese politician Sanae Takaichi. The live-fire drill not only tests Japan's response capabilities but also signals China's willingness to assert its maritime claims forcefully. For businesses operating in the region, such tensions raise concerns about supply chain disruptions and increased insurance costs.
Key Takeaways

FAQ
What is Japan's exclusive economic zone?
An exclusive economic zone (EEZ) is a sea zone prescribed by the United Nations Convention on the Law of the Sea over which a state has special rights regarding exploration and use of marine resources. Japan claims an EEZ extending 200 nautical miles from its coast, including around Okinotori Island.
Why does China disagree with Japan's claim over Okinotori?
China argues that Okinotori is a reef, not an island, because it is largely submerged at high tide. Under international law, reefs do not qualify for an EEZ. Beijing uses this interpretation to justify its military and research activities in the surrounding waters.
How has Japan responded to the live-fire drill?
Japan mobilized air and naval surveillance assets to track the Chinese and Russian vessels. It also protested through diplomatic channels, stating that the drill endangered navigation. Japan continues to monitor the situation closely and has called for restraint from all parties.
What are the potential economic impacts of these tensions?
Geopolitical tensions in East Asia can disrupt shipping routes, increase insurance premiums for vessels, and create uncertainty for businesses reliant on smooth trade flows. Companies with supply chains passing through the region should assess their exposure and consider contingency plans.
