US, Japan and South Korea meet to discuss tougher measures against N. Korea

Foreign ministers for the United States, Japan and South Korea met in New York on Sunday, ahead of UN meetings, to discuss stepped-up measures against North Korea and expand collaboration with one another after Pyongyang's fifth and largest nuclear test.

The Sept. 9 blast was in defiance of UN sanctions that were tightened in March.

The meeting between US Secretary of State John Kerry, Japanese Foreign Minister Fumio Kishida and their South Korean counterpart, Yun Byung-se, was the first since the latest nuclear test. It will be one of the main issues discussed by world leaders at the United Nations General Assembly this week.
