"President Trump and President Moon will continue their close coordination on efforts to achieve the final, fully verified denuclearization of the Democratic People's Republic of Korea," the White House said in a statement, using North Korea's official name.

The White House said Trump's visit to South Korea would combine with his visit to nearby Japan, where he will attend a G20 summit in Osaka on June 28-29.

Trump has made attempts to negotiate with North Korea a top priority. However, his two summits with all-powerful leader Kim Jong Un have produced no breakthrough in getting the totalitarian state to relinquish its nuclear weapons.
