Japan, the United States and South Korea will bring their foreign ministers together by the end of the month to coordinate efforts to pressure North Korea over its weapons-testing activities, diplomatic sources say.

Foreign Minister Fumio Kishida, U.S. Secretary of State Rex Tillerson and South Korean Foreign Minister Yun Byung Se will affirm their commitment to strengthening sanctions against the North if it continues provocative activities, including another nuclear arms test, the sources said Saturday.
