North Korea is ready to allow international inspectors into its nuclear and missile sites.
That breakthrough coming from U.S. Secretary of State Mike Pompeo, who held talks with Kim Jong Un over the weekend.
Inspectors were one of the key sticking points in Kim's earlier pledge to denuclearize.
Pompeo says Kim agreed inspectors will be invited to two testing sites.
One is a missile engine test facility.
The other is the Punggye-ri nuclear site that Pyongyang said was destroyed in May, though it only invited journalists to witness its destruction.
Not nuclear inspectors.
Pompeo also said the two sides are 'pretty close' to finalizing a second meeting between U.S. President Trump and the North's Supreme Leader.
State media on Monday (October 8) say Kim called Pompeo's visit 'productive and wonderful'.
That's a shift in tone from North Korean headlines after previous talks, where they accused Pompeo of making 'gangster-like' demands.
The North's state media say Kim also believes the dialogue between the two countries would move forward, 'based on the deep confidence' between himself and Trump.
He also thanked Trump for working to make good on what was agreed at their June summit in Singapore.
A U.S. official who was part of Pompeo's delegation said the trip was 'better than last time' but also said 'it's going to be a long haul'.
Pompeo next heads to China where he's slated to meet with President Xi Jinping in Beijing.
