STOCKHOLM, May 25 (Xinhua) -- UN Secretary General Ban Ki-moon said Monday he felt deeply worried by the nuclear test of Democratic People's Republic of Korea (DPRK), according to reports reaching here from Copenhagen.
"I am deeply worried by the report of nuclear test," Ban told Danish public television TV2 during his visit to the Danish capital for World Business Summit on Climate Change.
"I closely follow the situation in the region and am consulting with the United Nations Security Council, which is to hold an emergency meeting today in New York," Ban said.
Ban said that if the nuclear test is confirmed, it constitutes a clear violation of Security Council resolution 1718, which asks Pyongyang to restrain from such tests.
Ban emphasized that all difficulties should be resolved through dialogue, and encouraged the DPRK to return to its commitment to the international community.
The latest nuclear test by Pyongyang came after the UN Security Council adopted a presidential statement in late April, condemning the April 5 rocket launch by the DPRK and demanding the country "not conduct any further launch."
Pyongyang subsequently announced it was quitting the six-party talks on nuclear disarmament and would restart nuclear facilities in protest of the UN statement.
