U.S. Secretary of State Mike Pompeo on Monday said he will visit Pyongyang again in the near future, during an address to business leaders in Detroit.

While he did not provide specific details on the timing of the visit, the Secretary of State said the two sides continued to work on issues raised at last week’s summit between U.S. President Trump and Kim Jong Un.

“There’s a lot of work between here and there. My team is already doing it. I’ll likely travel back before too terribly long,” Pompeo said.

The visit would be Pompeo’s third visit to Pyongyang since April,
