U.S. Secretary of State Mike Pompeo has wrapped up his fourth visit to North Korea... and is now in Seoul, where he'll brief South Korean President Moon Jae-in and foreign minister Kang Kyung-wha.
For more, we go to Lee Ji-won following this story at the foreign ministry in Seoul.
Ji-won, what do you have for us?

Devin, we heard that Secretary Pompeo landed at the U.S. air base in Osan, South Korea at 5:13 p.m., local time.
We are told that he has two schedules here.
The first is to meet with South Korean President Moon Jae-in at 7 in the evening.
He'll brief the President on what was discussed and hopefully agreed on in his talks with the North Korean leader earlier in the day.
Secretary Pompeo is then due to hold a working dinner with Seoul's foreign minister Kang Kyung-wha.
These events will be held behind closed doors, so I'm not sure how much detail we'll be able to get on it.
After staying overnight, Secretary Pompeo is then expected to leave for China on Monday.

Ji-won, this is Pompeo's fourth visit to Pyeongyang, and this time he did meet with Kim Jong-un.
And Pompeo tweeted less than an hour ago that he had a "good trip" to the North and posted a photo with Kim.
Can you tell us what they might've talked about?

Devin, Pompeo told reporters en route to Japan a couple days ago, that the mission was to make sure both sides understand what the other is truly trying to achieve and that both need to develop sufficient trust to take concrete actions.
And amid renewed hopes since the latest inter-Korean summit, many were hoping that the two sides would really give something to each other in these talks.
That could include the U.S. declaring an end to the Korean war, which the North has continuously asked for.
And the North had promised that with "corresponding measures" from the U.S., that it would take additional measures such as dismantling its key nuclear facility.
The two sides are also expected to have covered preparations for the second North Korea-U.S. summit.
But Secretary Pompeo doubted that a decision would be made today, saying that they will begin to develop options for both location and timing.
And Devin, this was the first time that U.S. Special Representative for North Korea Stephen Biegun has gone to Pyeongyang and met with the regime's leader.
So, with Biegun accompanying Pompeo, hopefully the two negotiators were able to make some progress in their talks.
That's all from me at this hour Devin.
