Meanwhile, the U.S. envoy for North Korea, Stephen Biegun, has been holding talks with his North Korean counterpart in Pyongyang ahead of the second summit between their leaders.

The U.S. Special Representative for North Korea, Stephen Biegun, arrived in North Korea on Wednesday... to iron out the details ahead of the upcoming second summit between Kim Jong-un and President Trump.
According to the U.S. State Department, Biegun will be meeting with his new North Korean counterpart, Kim Hyok-chol, the North's former ambassador to Spain.
And a South Korean official says there's a high chance that Biegun will spend the night in North Korea.
These working-level talks are to prepare for the second Kim-Trump summit.
The two sides will be discussing what North Korea should do next and what the U.S. can give in return.
Last week, speaking at Stanford University, Biegun said... when Secretary Pompeo visited Pyeongyang in October last year, Kim Jong-un promised to dismantle his regime's plutonium and uranium enrichment facilities "beyond" those in Yongbyon.
Also, Kim agreed to invite American experts to verify the destruction of the Punggye-ri nuclear test site.
Biegun also stressed that the U.S. needs to have a full understanding of the North's nuclear program and ultimately ensure that the relevant materials and weapons are moved out of the country.
So those are expected to be the U.S. demands to the North.
And in return, it's likely that Washington will offer economic benefits including sanctions relief.
The Washington Post has previously reported that the U.S. is quietly preparing a special "economic package" to draw Pyeongyang into denuclearization.
Trump also recently stressed that Kim Jong-un has an opportunity to make North Korea a "tremendous economic behemoth" if he denuclearizes.
Also on the list could be establishing a joint liaison office, declaring an end to the Korean War and providing humanitarian aid.
