President Moon Jae-in's special security adviser says that South Korea still believes in the usefulness of the dormant six-party nuclear talks on North Korea's denuclearization.

Moon Chung-in, presidential special adviser on foreign affairs and national security, made the remark on Tuesday at a forum held in the United States. 

The security adviser said that the government hopes to resume the talks at an early date to resolve the North Korean nuclear issue through dialogue and negotiation.

He added that realizing a peaceful, nuclear-free Korean Peninsula is the goal of the Moon Jae-in government.

The adviser said that to that end, the Seoul government upholds three principles -- pursuing a nuclear-free Korean Peninsula, putting peace first and seeking domestic consensus and international cooperation. 

Regarding the prospect of talks between the U.S. and North Korea, the presidential adviser said that the Seoul government is dealing with the matter with "maximum prudence."
