Japan, the United States and South Korea are planning to hold a foreign ministers' meeting in Washington around March 16 to discuss recent agreements between North and South Korea, diplomatic sources said Wednesday.

The planned meeting follows talks this week in Pyongyang between North Korean leader Kim Jong Un and envoys of South Korean President Moon Jae-in, at which the South Korean government said Kim expressed readiness for dialogue with the United States.

For Japan and the United States, the meeting is likely to be aimed at warning South Korea of their concerns that North Korea's overtures to the Moon administration could compromise the effectiveness of sanctions imposed on the North, the sources said.
