Foreign Minister Yun Byung-se met with U.N. Secretary-General Ban Ki-moon in New York to coordinate their response to North Korea's nuclear and missile tests, the Foreign Ministry said Wednesday.

Yun flew to New York on Tuesday to drum up support for a strong U.N. resolution that will punish the North for its fourth nuclear test and long-range rocket launch.

The U.N. Security Council began work on a new resolution shortly after the North claimed it detonated a hydrogen bomb on Jan. 6. On Sunday, North Korea fired a long-range rocket into space in an apparent test of its ballistic missile technology.

In his meeting with Ban, Yun stressed the importance of adopting a resolution that will force North Korea to change its course, noting the communist country has repeatedly violated past U.N. resolutions.

"We need to respond with a stern determination that this resolution will be the last Security Council resolution," the ministry quoted Yun as saying.

Ban expressed "deep concern" over the North's nuclear test and long-range rocket launch, saying they are in violation of U.N. Security Council resolutions and create instability.

He also voiced hope that a new resolution would be adopted soon. (Yonhap)
