Japan may release data it says will prove a Chinese naval vessel directed its fire control radar at a Japanese destroyer near disputed islands in the East China Sea, local media reported.
China’s military denies the warship locked its radar onto the Japanese vessel on Jan. 30, but the incident has added to tensions between the two nations over the disputed islands.
Japan will consider how much normally classified data it can release, the media reports said, citing comments by Japan Defence Minister Yoshinori Ono on local television.
Japan and China have been involved in a series of incidents in recent months in the East China Sea where Chinese and Japanese naval vessels regularly shadow each others movements.
Both countries claim a small clusters of islands, known as Diaoyu in China and Senkaku in Japan, believed to be rich in oil and gas. Controlled by Japan, possession of the uninhabited outcrops and the sea surrounding them would provide China with easier access to the Pacific.
Hopes had been rising for an easing in tensions, including a possible summit between Japanese Prime Minister Shinzo Abe and Chinese leader Xi Jinping. But the radar issue has seen China and Japan engage in a fresh round of invective.
