Japan's coastguard said Monday it was searching for seven people missing after their boat capsized and was spotted in waters off the Tokyo-controlled Senkaku islets, which are also claimed by China.

The overturned boat was spotted on Sunday afternoon, drifting in waters north of the islands by a Japanese navy patrol in the area, coastguard spokesman Keisuke Nakao told AFP.

The crew are one Taiwanese and six Indonesians, he added.

"We have been searching the area with patrol ships and helicopters since receiving the information at around 1:30 pm (0430 GMT) Sunday" from the Maritime Self-Defense Force, he said.

Nakao also said Japanese authorities were coordinating with their counterparts in Taiwan, which also lays claim to the Senkaku islets. Beijing calls the uninhabited territory the Diaoyu Islands.

Taiwan's foreign ministry confirmed in a statement that the vessel was a Taiwan-registered fishing boat, and was suspected to have capsized near one of the Senkaku Islands.

"The National Rescue Command Centre has contacted Taiwanese fishing boats near the site of the accident to assist in the search. Taiwan and Japan's coastguards have also dispatched ships for search and rescue," the statement said.
