"We will be laying out our expectation for North Korea to take concrete steps to begin to make real the denuclearization that Kim Jong-un committed to. The president is very optimistic," Mike Pence told Fox News.
Commenting on Trump's attitude, the vice president said that the US president believes "we can make real progress," and Washington would continue to strive for ridding the Korean Peninsula of nuclear weapons.
Mike Pence's remarks come after the White House said this week that the second summit would be held at the end of February. The location will be announced later. The first landmark meeting took place in Singapore last June.
