North Korea has pledged to shutter its missile engine testing site and allow external inspectors to verify the process in a move aimed at demonstrating the regime's sincerity about denuclearisation.
Pyongyang said it would also close its sprawling Yongbyon nuclear site if the US responds with the concessions it pledged during the Singapore summit between the two nations in June.
Such a concession would like be a declaration ending the officially unfinished Korean war.
The pledges by the North Korea regime came during a summit between leader Kim Jong Un and South Korean President Moon Jae-in in Pyongyang on Wednesday.
The two men vowed to pursue peace on the peninsula, which they said was the will of all Korean people on either side of the border.
"We are opening a new era of peace that will lead to the complete denuclearisation of the peninsula," Mr Moon said. "Denuclearisation will happen in the near future."
US president Donald Trump welcomed the agreements, noting on Twitter that the developments were “very exciting”.
