Chinese Patrol Boats Return to Disputed Islands

The islands are uninhabited but potentially resource rich

 Chinese government ships returned to waters off disputed Japanese-controlled islands on Tuesday, the coastguard said, a week after they last left and days after heated exchanges at the United Nations.

Four maritime surveillance ships entered the waters shortly after 12:30 pm (0330 GMT), where they remained for around six hours, ignoring demands from Japan's coastguard to leave.
