South Korean President Moon Jae-in and U.S. President Donald Trump spoke on the phone last night and had a pretty long conversation... lasting over an hour.
They discussed the outcome of the historic inter-Korean summit on Friday... and plans for the U.S.-North Korea summit.
Oh Jung-hee is on the line for us with more.
Jung-hee, fill us in.

Good morning, Jiyeon.
South Korea's presidential office confirmed this morning that President Moon Jae-in spoke with U.S. President Donald Trump last night... for 1 hour and 15 minutes.
President Trump first congratulated President Moon on the successful inter-Korean summit... and said it represents significant progress in Seoul-Pyongyang relations.
President Moon replied that the inter-Korean summit lays the groundwork for success in President Trump's own summit with the North Korean leader.
The leaders of Seoul and Washington reaffirmed that their governments will continue to coordinate closely to achieve the complete denuclearization of the Korean Peninsula.
Now, on that front, the two agreed that it will be helpful to hold a Washington-Pyongyang summit as soon as possible to keep up the momentum of the inter-Korean summit.
They have narrowed the possible locations of the meeting down to two or three.
President Trump said he's very much looking forward to meeting with the North Korean leader.
Meanwhile, President Trump tweeted last night that he had (quote)"a long and very good talk" with President Moon... and that things are going very well.
He added that the time and location of his meeting with Kim Jong-un is also being set.
Back to you, Jiyeon.
