TOKYO: Japan said Friday it was monitoring waters near islands disputed with China in the East China Sea after it spotted a naval intelligence ship from the country operating in a new area for the first time.
Japan’s Defense Ministry said late Thursday a P-3C patrol aircraft observed the Dongdiao-class intelligence vessel near territorial waters of the Senkaku Islands, which Japan administers but China claims as the Diaoyus.
Japan and China have routinely butted heads over ownership of the uninhabited islets, as Chinese state ships — mostly coast guard — and aircraft have approached them on and off to back up Beijing’s claims and test Japan’s response.
Relations between Japan and China hit multi-year lows after the Japanese government in September 2012 moved to increase its formal control by nationalizing some of the islands.
But China and Japan — Asia’s two biggest economies, respectively — have taken steps to improve ties.
They issued carefully worded statements on the dispute ahead of a summit last year in Beijing between Chinese President Xi Jinping and Japan’s Prime Minister Shinzo Abe.
The two sides basically acknowledged they had different views on tensions emanating from the issue but agreed on the need for keeping them under control.
Distrust, however, remains high, as China is wary of moves by Abe to raise Japan’s military profile while Tokyo frets about Beijing’s increasing regional and global assertiveness.
The latest move marked the first time a Chinese naval ship operated in the area between the disputed islands and the populated southern Japanese island of Miyako, a defense ministry spokeswoman told AFP.
“We will continue our monitoring activity as we have before,” she said, speaking on condition of anonymity.
The ship repeatedly moved back and forth in the area until Thursday evening before departing, never breaching Japan’s 12-nautical-mile territorial waters, the ministry statement said.
The 6,000-ton vessel is armed with one 37 millimeter and two dual 14.5 millimeter cannons, the ministry said, citing IHS consultancy group’s Jane’s Fighting Ships site.
The mass circulation Yomiuri Shimbun daily reported that Japan would strengthen border security as a result of the spotting.
Anonymous sources from the ministry told the Asahi Shimbun newspaper the Chinese ship might have been there on an intelligence mission ahead of a planned drill this month by Japan’s naval forces.
