Japan issues formal protest after Chinese ship sails near territorial waters
Japan has formally protested to China after one of its naval warships sailed close to an area that Japan considers to be its territorial waters. Although tensions have been mounting between the two nations, this is the first time that China has entered waters that are contiguous to what Japan regards as its territory. The incident took place near the disputed Senkaku/Diaoya islands. In response, Japan summoned the Chinese ambassador to the capital, Tokyo. China has said that it will look into the matter, but argued that the Diaoya islands are Chinese and as such, the navy has every right to operate nearby. The uninhabited islands are controlled by Japan, but claimed by China.

Japan has summoned the Chinese ambassador in Tokyo after a Chinese navy ship sailed close to what Japan considers its territorial waters in the East China Sea for the first time.



The Japanese foreign ministry said the Chinese warship had entered waters that are contiguous to what Tokyo considers its territory in the vicinity of disputed islands, known as the Senkaku in Japan and the Diaoyu in China.

The incident shortly after midnight on Thursday could be a setback for signs of improvements in relations between Asia’s two largest economic powers, which had soured in recent years over their wartime history and territorial rows.

Japan’s vice foreign minister Akitaka Saiki summoned the Chinese ambassador in Tokyo at around 2am on Thursday local time to “express a serious concern” and urge the Chinese ship to leave the area, the ministry said in a media statement.

The Chinese frigate left the waters about an hour later, sailing to the north, the Japanese defence ministry said.

China’s defence ministry said it was looking into the reports but in a statement sent to Reuters, the ministry said the islands are Chinese, and that China’s navy had every right to operate in Chinese waters.

Chinese patrol ships have occasionally sailed close to or entered what Tokyo considers its territorial waters, but this was the first time that a Chinese naval ship made its way into those waters.

At around the same time, three Russian battleships entered waters close to what Japan considers its territory, the defence ministry said. The ministry said it was investigating whether the Chinese and Russian actions were related.

None of the ships violated what Japan considers its territorial waters, it said.

The uninhabited East China Sea islands lie about 135 miles (220km) north-east of Taiwan and are controlled by Tokyo but claimed by Beijing.

There was no immediate comment from Beijing but China in the past has warned Japan not to take any “provocative” action over the disputed islands. Chinese ships sailed near the disputed islands last year.

Japan in turn in the past has told China that any foreign naval vessel that entered Japanese waters for reasons other than “innocent passage” would be told to leave by a Japanese naval patrol.
