Japan, South Korea and the United States in a joint statement Friday praised North Korea for opening bilateral dialogue with all three nations following the Stalinist state's agreement to hold the first-ever inter-Korean summit in June.

"The recent developments . . . represented an unprecedented opportunity to enhance peace and stability in Northeast Asia," said a statement released by the Trilateral Coordination and Oversight Group following a one-day meeting at the U.S. Embassy in Tokyo.

The group members reiterated their "continuing commitment to consult closely and to coordinate their respective policies" toward the North.
