Only if talks between high-rank officials happen and lead to substantial progress, the third North Korea-United States summit is possible, as you know, the North side has shown the year-end deadline, considering that position of the North Korean side, we are closely coordinating with the U.S. side for North Korea and United States to find clues.

We take a very grave view of this situation and, if it is repeated, we will take even stronger action.

White House aides believe there is a 99.9 % chance the North Korea-US summit will be held as scheduled, but White House aides're just preparing for many different possibilities.

President Trump remembered, and as Chung Eui-yong said well-wishing remarks about Chairman Kim Jong Un's birthday, President Trump requested that it'd be good if President Moon can deliver that message to Chairman Kim Jong Un, as far as I know, such message has been delivered to the North in an appropriate way.
