Japan and South Korea to Collaborate on Radar System for North Korean Missile Tracking.

Japan and South Korea are expected to agree early next month to link their radars via a U.S. system to share real-time information on North Korea's ballistic missiles. Defence ministers from Japan, South Korea and the United States plan to reach an agreement on the sidelines of an Asian defence summit to be held in Singapore early next month. Ties between the United States' Asian allies have warmed in recent months in the face of the North Korean threat.
