Armed Chinese ship infiltrates waters off disputed Senkaku Islands, Japan Coast Guard says


An armed Chinese coast guard vessel entered Japanese waters off the disputed Senkaku Islands for the first time on Saturday, Japanese authorities said.

The Japan Coast Guard said the ship, armed with what appeared to be four gun turrets, was one of three Chinese coast guard vessels spotted inside Japanese waters in the East China Sea. It was the only one that was armed.

Chinese vessels regularly sail around the islands, which China calls the Diaoyu. But Japan Coast Guard official Nanako Uehara said it was the first time an armed Chinese vessel had been sighted in Japan’s waters.

The three vessels have left the area.

The armed ship also was spotted Tuesday in the area, but it didn’t infiltrate Japan’s waters at that time.

The development could trigger concern in Japan that China may be escalating its activities in the disputed parts of the East China Sea.

Last month, a Chinese Navy ship took its time traversing the waters. Japan earlier this year protested China’s unilateral exploration of undersea oil and gas deposits in the East China Sea, posting photos online of Chinese drilling equipment.

Relations between the two countries also have been strained over wartime history, though there have been signs of improvement recently.
