Japan and Canada agreed Tuesday to send a "strong message" on North Korea's nuclear and ballistic missile programs at this year's Group of Seven advanced nations' meetings, to be hosted by Canada.

While Foreign Minister Taro Kono and his Canadian counterpart Chrystia Freeland did not make clear exactly what that message will be, they affirmed that Japan and Canada will maintain pressure on the North ahead of planned inter-Korean and U.S.-North Korean summits.

"As the situation in North Korea and the rest of the world becomes more uncertain, it's increasingly important for the G-7 nations to coordinate in leading the international community," Kono said at a joint news conference after the talks with Freeland in Tokyo.
