Working level talks between North Korea and the U.S. for the second Kim-Trump summit have wrapped up and U.S. Special Representative for North Korea Stephen Biegun is back in Seoul.
For more, let's go straight to our Park Hee-jun who's at the foreign ministry.
Hee-jun, what's the latest?
Seoul's foreign ministry has confirmed that Biegun has returned from Pyeongyang.
An American military aircraft carrying the U.S. delegation landed at the U.S. Air Base in Osan around 7PM, roughly an hour ago.
Since his departure to the North on Wednesday, Biegun's had three days to negotiate the details of the upcoming Vietnam summit with this North Korean counterpart Kim Hyok-chol.
The State Department originally announced that his visit to Pyeongyang would only be a one-day affair.
However, Biegun's extended stay could be an indication of substantial talks on a number of key topics ahead of the scheduled summit between Kim Jong-un and Donald Trump.
And that most likely involves finding concessions that can satisfy each of their demands.
Washington has called for concrete steps toward complete, verifiable denuclearization, and the dismantling of North Korea's missile inventory.
Pyeongyang on the other hand, has been demanding the U.S. to remove its economic sanctions on the regime.
We don't know yet how much progress the U.S. delegation has made on all of these fronts as it returns from North Korea.
A detailed agreement on these issues is seen to be essential, to ensure the success of the upcoming summit.
For now, we'll have to wait for other annoucements that may follow, which may even include the exact venue for the summit in Vietnam.
And before flying back to Washington, Biegun is expected to share the results of the Pyeongyang negotiations with his South Korean counterpart Lee Do-hoon, and Foreign Minister Kang Kyung-wha on Saturday.
According to a foreign ministry official, Biegun has promised to brief the South Korean government first, on the details of what was discussed in Pyeongyang.
He's also likely to brief with his Japanese counterpart as well.
According to Japan's Kyodo News, Tokyo's top nuclear envoy Kenji Kanasugi is scheduled to visit Seoul on Friday, to meet Lee Do-hoon and Stephen Biegun during his stay.
Biegun will then return to the U.S. on Sunday. Back to you, Daniel.
