Five permanent members of the U.N. Security Council and Japan met Monday at the U.N. headquarters in New York to discuss responses to North Korea’s rocket launch. But the six countries reached no agreement.

Ahead of the meeting, Japan’s U.N. Ambassador Yukio Takasu urged a strong, effective countermeasure to the North’s launch. U.S. Secretary of State Hillary Clinton also declared Washington’s support for a strong response from the Security Council.

But Russian U.N. Ambassador Vitaly Churkin warned against an emotional knee-jerk reaction, calling instead for a common strategy. He said the key element is reviving the six-party nuclear talks for the denuclearization of the Korean Peninsula.

The council will discuss the North Korean issue in small group meetings for the time being before holding a full session.

Diplomatic sources say a basic outline of the council’s reaction to the launch is expected to emerge around this weekend.
