"During the meeting, the United States and the Republic of Korea shared updates on efforts to achieve our shared goals of a final verified denuclearization, including through the implementation of UN Security Council resolutions", Palladino told reporters.
He noted that the bilateral working group is meeting on routine base as a "part of comprehensive and close coordination over North Korea".
"They are talking about the summit" between US President Donald Trump and North Korean leader Kim Jong Un, he added.
The second summit between Trump and Kim concluded with no agreement signed in the Vietnamese capital last week. Trump walked away from the talks, saying that Kim demanded full sanctions removal, while not pledging to denuclearize exactly the facilities that Washington wanted.
