Two Chinese vessels chase Japanese fishing boat near disputed islets

Japan lodged an official protest with China over the incident -- which took place on Friday -- via a call to the Chinese Embassy in Tokyo by Shigeki Takizaki, head of the Japanese foreign ministry's Asian and Oceanian Affairs Bureau, local media reported.

There was also a call from the Japanese Embassy in Beijing to the Chinese Foreign Ministry, media said.

Contacted by AFP, the Japanese foreign ministry could not immediately confirm the reports.

The flashpoint islands, called Senkaku in Japan and known in China as the Diaoyus, are at the centre of a festering row between Tokyo and Beijing.

The Japanese government has long complained about China's routine dispatch of its coast guard ships to waters surrounding the islands.

On Friday the Japan Coast Guard ordered the Chinese vessels to leave the waters, and deployed several patrol ships to safeguard the fishing boat, whose three crew members were unhurt, a coast guard spokesman told AFP.

Two "Chinese ships loitering around the islands are still inside the Japanese territorial waters," he said Sunday, adding "the fishing boat is not in a dangerous situation".

Relations between Japan and China deteriorated in 2012 when Tokyo "nationalised" some of the disputed islets.

Since then, the two top Asian economies have taken gradual steps to mend fences but relations at times get tense.
