April 28 (Asia Today) -- South Korea's foreign ministry called North Korea's nuclear program the most urgent challenge facing the global nonproliferation regime and urged stronger international support during a United Nations conference.

Jeong Yeon-doo, head of policy planning at the foreign ministry, made the remarks Monday at the 11th Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons held at U.N. headquarters in New York.

"North Korea is the only case that has benefited from the NPT system, declared withdrawal and continued to openly develop nuclear weapons," Jeong said in a keynote address. "This makes it the most urgent challenge to the nonproliferation regime."

He said South Korea remains committed to the complete denuclearization of the Korean Peninsula and lasting peace, adding that Seoul will pursue a phased approach aimed at halting, reducing and ultimately dismantling North Korea's nuclear program through dialogue and cooperation.
