A flurry of diplomatic activity here on the Korean Peninsula ahead of talks between North Korea and the U.S.
Secretary of State Mike Pompeo is on his second trip to North Korea.
Unlike his first visit in early April, this one was made public by President Trump himself as he announced the end of the Iran deal on Tuesday.
For more, we connect to our unification ministry correspondent Oh Jung-hee.
Jung-hee, so Mike Pompeo is in Pyongyang again. What do we know so far about that? And when are we going to hear more about plans for the summit?

Hi, Mark.
We're hearing from AP that U.S. Secretary of State Mike Pompeo arrived in Pyongyang this morning for pre-summit meetings with North Korean officials.
The fact that he left for North Korea was announced unexpectedly by U.S. President Donald Trump on Tuesday during his announcement on the Iran deal.
Take a listen.

"Secretary Pompeo is right now going to North Korea. He will be there very shortly, in the matter of, virtual, probably an hour. He's got meetings set up."

We do not know for sure who Secretary Pompeo is going to meet.
But the fact that he is making his second visit to North Korea in just about a month could be a sign that new progress has been made regarding the first-ever summit between the leaders of North Korea and the United States.
And, noting what President Trump has said,... it seems likely that the date and location of the Pyongyang-Washington summit could be announced soon.

"We have our meeting scheduled. We have our meeting set. The location is picked. The time and date, everything is picked. And we look forward to have a great success. We think relationships are building with North Korea. We'll see how it all works out. Maybe it will, maybe it won't. But it can be a great thing for North Korea, South Korea, Japan and the entire world. We hope it all works out."

Jung-hee, the understanding is that Pompeo is in the North to finalize the agenda for the scheduled North Korea-U.S. summit. One thing President Trump wants to talk about, of course, is the issue of the three American detainees.
Can we expect any progress on that front?

Well, when asked whether the three Americans detained in North Korea would be released,... President Trump said related news would come soon,... adding that it would be a great thing if they were to come home.
Hopes are high that the three Americans could return to the U.S. with Pompeo.
And that's especially because, in contrast to Pompeo's last Pyongyang visit that was completely secret,... this visit involves a couple of American reporters -- raising the prospect that the Trump administration might want to create a dramatic scene.
On his way to Pyongyang, Pompeo told reporters... he had not yet received a commitment from the regime that it will release the detainees.
He added he will bring up the issue,... saying he hopes Pyongyang will (quote) "do the right thing."
Back to you, Mark.
