The Japan Coast Guard, have said that China and South Korea have cancelled participation in a multinational naval security exercise that began on Saturday. The U.S. Canada and Russia are taking part in the exercise.Although Japanese officials refused to give a specific reason for the cancellation, South Korea said it was because of concerns that part of the exercises may upset North Korea, whose nuclear ambitions are a major regional concern.
However, China and South Korea were expected to rejoin the manoeuvres next month, a Japanese official said.
