The Democratic People's Republic of Korea (DPRK) said on Tuesday that relations with the United States will develop “wonderfully at a fast pace” with "definite and epoch-making steps" if Washington responds to its efforts on denuclearization with "trustworthy measures and practical actions."

DPRK's envoy to the United Nations in Geneva, Han Tae Song, made the remarks at the UN-sponsored Conference on Disarmament.

Pyongyang would continue working to establish a “permanent and durable peace mechanism on the Korean peninsula,” Han added.

Han pointed out that the summit last June between DPRK leader Kim Jong Un and US President Donald Trump had brought about a dramatic turn in relations that had been “the most hostile on earth” and contributed to ensuring peace and security on the divided peninsula.

"Accordingly we declared that we would neither make and test nuclear weapons any longer nor use and proliferate them, and we have taken various practical measures," Han noted, referring to the joint statement issued after the first Trump-Kim summit and Kim's New Year's Address.

Summit agreement draft is likely on the way: NIS chief

The US and DPRK will likely start preparing a joint statement of Kim and Trump to be issued at their second summit scheduled for next month, the head of Seoul's National Intelligence Service (NIS), Suh Hoon said Tuesday.

"I believe they will begin coordinating topics for the summit in order to draft a joint declaration in the DPRK-US working-level negotiations, along with their working-level preparations for the second DPRK-US summit such as safety and protocols," the NIS chief was quoted as telling the parliamentary intelligence committee.

"As both the DPRK and the US are expressing satisfaction, and their working-level negotiations have begun in the earnest, we expect denuclearization talks to get a push," Suh added.

The US president said his second meeting with Kim would likely be held late next month shortly after he was paid a visit by Kim's point man on the US, Kim Yong Chol.

The NIS chief said the DPRK official's trip to Washington earlier this month appears to have been well received and led to "discussions on a wide range of issues in a friendly mood."

Republic of Korea's foreign minister told Reuters at Davos last week that the DPRK must make concrete pledges towards curbing its nuclear weapons program, such as dismantling its main nuclear complex and allowing international inspections to confirm the process when leader Kim meets Trump as soon as next month.
