A Chinese warship fired live rounds inside Japan’s exclusive economic zone (EEZ) for the first time, marking a significant escalation in regional tensions. The live-fire drill occurred on Sunday, just a day before Chinese and Philippine sailors clashed in the South China Sea, highlighting Beijing’s growing assertiveness in disputed waters.
Details of the Live-Fire Drill in Japan’s EEZ
Three Chinese warships and a Russian frigate were spotted sailing between Okinawa’s main island and Miyako island into the Pacific on Thursday. By early Sunday, the Chinese missile destroyer was detected around 330 kilometers southwest of Okinotori, where it issued a warning to shipping about the drill. The exercise reportedly included machine guns using live ammunition, conducted about 180 kilometers from Okinotori—Japan’s southernmost island, which defines part of its EEZ.
Tokyo responded by mobilizing air and sea surveillance efforts. Japan’s top government spokesman, Minoru Kihara, stated that the drill “could have endangered the navigation of nearby ships” and that Japan had lodged a diplomatic protest with Beijing. He added, “We will continue to monitor with concern the behaviors by Chinese and Russian vessels in the waters around our country.”
Beijing’s Position and Disputed Island Status
Beijing disputes Okinotori’s designation as an island, maintaining that it is a reef and therefore not part of Japan’s EEZ. This legal argument allows China to claim freedom of navigation and military operations in the area. A Chinese aircraft carrier and research ship both entered these waters in 2025, but this is the first time Japan’s defense ministry has acknowledged a foreign navy vessel firing live rounds in the EEZ.
Escalating Military Exercises Around Japan
Chinese and Russian military exercises have ramped up around Japan since Tokyo’s relations with Moscow soured over the war in Ukraine. A diplomatic row with Beijing over comments by Japanese politician Sanae Takaichi has further strained ties. The live-fire drill represents a new phase in this strategic competition, with both China and Russia signaling increased cooperation in the region.

FAQ
What is Japan’s exclusive economic zone (EEZ)?
Japan’s EEZ extends 200 nautical miles from its coastline, giving it sovereign rights over marine resources. Okinotori is a key island defining part of this zone, though China claims it is a reef.
Why did China fire live rounds in Japan’s EEZ?
China asserts that Okinotori is a reef, not an island, so the waters are not part of Japan’s EEZ. This allows Beijing to conduct military drills there as part of its broader regional strategy.
How has Japan responded to the Chinese drill?
Japan mobilized surveillance assets, lodged a diplomatic protest, and expressed concern over navigation safety. Tokyo continues to monitor Chinese and Russian naval activities closely.
