Kim Jong Un, as he has on his previous two visits.
Regarding fears that the US may have softened its expectations in the denuclearization process, State Department spokesperson Heather Nauert - who is accompanying Pompeo to Pyongyang - said their policy had not changed and that they are "committed to a denuclearized North Korea".
Japan said it is ready to normalize ties with and provide economic support to North Korea following a comprehensive resolution of the nuclear, missile and abduction issues, according to the sources.
Officials were also expected to hash out the return of the remains of U.S. soldiers killed in the 1950-53 Korean War.
Kim Yong Chol welcomed Pompeo to North Korea, noting that it was his third visit to the country.
North Korea has one of the world's largest navies by number of ships.
What position it will take on the nuclear issue appears to be anything but a done deal.
North Korea has consistently refused in past rounds of failed negotiations to provide an inventory of its weapons program, and USA intelligence remains uncertain of how many nuclear warheads North Korea has. "I don't think there's any doubt about that".
At one of the lowest points in US-North Korean relations since Trump took office, the US president frequently called Kim "little rocket man" in Trump's speeches and tweets in 2017. "As it is declared that there will be no more war on the Korean peninsula, there is no reason for THAAD to be in my country", said Lee, who hopes the system could be withdrawn within three months.
Kim has also met with China's President Xi Jinping and U.S. President Donald Trump.
What exactly Washington has in mind, however, isn't entirely clear.
On one occasion in 2017, Trump sent his ghostwritten 1987 bestseller 'The Art of the Deal' via retired National Basketball Association star Dennis Rodman, who visited Pyongyang several times before.
On Tuesday, Nauert walked that back, declining to give a timeline.
At the Singapore summit, Kim Jong Un made a broad commitment to "work toward denuclearisation", but fell short of details on how or when he would dismantle North Korea's nuclear programme, which it has pursued in defiance of U.N. Security Council resolutions.
Pyongyang will be the first stop on his first around-the-world trip as America's top diplomat. He will then travel to Japan, Vietnam and the United Arab Emirates before heading to Belgium, where he will accompany Trump at the North Atlantic Treaty Organisation summit in Brussels.
