Japan, the United States and South Korea reaffirmed on Sunday their intention to continue working closely together to curb North Korea's missile and nuclear weapons development.

Foreign Minister Fumio Kishida, U.S. Secretary of State John Kerry and South Korean Foreign Minister Yun Byung-se discussed their concerns about North Korean provocations, including recent short-range ballistic missile launches and the continuation of nuclear and missile development in violation of U.N. Security Council resolutions, a Japanese official said.

The three ministers met on the sidelines of the 27-member ASEAN Regional Forum, Asia's biggest security gathering, in the Myanmar capital Naypyitaw.
