TOKYO (AP) — Japan says it has protested to China after two Chinese patrol boats entered waters near islands in the East China Sea claimed by both countries.
Chief Cabinet Secretary Yukio Edano says two Chinese vessels entered Japanese waters off the islands known as Senkaku in Japan and Diaoyu in China early Wednesday. He says the boats left the area about 30 minutes later after warnings by Japanese Coast Guard patrol boats and aircraft.
Edano says Japan's government "strongly" protested to China and reiterated its claim to the islands.
Last year, a collision between a Chinese fishing trawler and Japanese patrol boats sparked a diplomatic spat. Japan says Wednesday's incident is the first time China has entered Japanese waters since then.
