The South Korean UN Secretary-General nominee said on Monday he would work towards resolving the North Korea’s nuclear bomb test crisis.

South Korean Foreign Minister Ban Ki-moon, who is set to succeed current Secretary-General Kofi Annan when he steps down from office at the end of the year, said that he will “contribute as much as I can to the resolution of all kinds of problems including the North Korean nuclear issue that may threaten international peace and security,” according to Dow Jones Newswires.

Following North Korea's announcement that it had successfully conducted an underground nuclear test on Monday, markets in its neighboring South Korea fell. The two countries share what has become infamously known as the world’s most heavily-armed frontier.
