Tony Kim, 59, an accountant, and Kim Hak-song, an agricultural consultant, were affiliated with Pyongyang University of Science and Technology, and both were detained after President Trumptook office past year.
Pompeo was speaking after talks with his South Korean opposite number Foreign Minister Kang Kyung-wha to prepare for a historic June 12 summit between US President Donald Trump and North Korean leader Kim Jong Un.
But since the Winter Olympics in the South, Pyongyang and Washington have agreed to the unprecedented Singapore meeting.
He described his conversations with Kim as "warm" and said both had tried "our best to make sure that we were communicating clearly and had shared understanding about what our mutual objectives were". "Those are the kind of things that if we get what it is the President has demanded - complete verifiable irreversible denuclearization of North Korea - that the American people will offer in spades". With U.S. help, those countries recovered from the devastation of conflict. To this, Kim will probably respond that securing any prisoner's release is hard, given North Korea's "independent" judiciary; but he will present himself as a humanitarian willing to do what he can to help.
Both PUST and YUST hire mostly Christian faculty says Ms. Shellnutt, including dozens of USA citizens, along with other foreigners, who consider the position missionary work.
It's more likely that Kim will put forward the wording he used in China this week promising "phased" measures created to "eventually" achieve denuclearization. "Commerce Department has been instructed to get it done!"
China is North Korea's most important economic and diplomatic backer, but Beijing has been irked by Pyongyang's repeated nuclear and missile tests and supported tough United Nations sanctions against its Cold War-era ally. But it is worth noting that he is also following his long-stated plan - first turning North Korea into a nuclear state to ensure its security and now focusing on improving its economy. For the sake of public opinion in South Korea, he will have to chart a course between upholding the spirit of the inter-Korean summit and not giving in on sanctions relief. The majority of people in North Korea live in poverty.
But it is a matter of fierce debate among diplomats and Korea experts whether Kim would surrender his nuclear arsenal. Pompeo said that the denuclearization would need to be verified and permanent in order for it to be considered complete, reported The Hill.
The announcement comes two days after Trump's maiden speech to the UN General Assembly, in which he nicknames Kim a "Rocket Man" on a "suicide mission" and warns that if threatened, the United States will have "no choice but to totally destroy North Korea".
A series of U.S. administrations have sent envoys, both official and unofficial, to Pyongyang in the hope of stopping North Korea's nuclear weapons program. Both sides say they hope for a breakthrough. It is not clear what, if anything, North Korea will agree to at the summit or what Kim means by denuclearization.
Pompeo said he had "productive" discussions with Kim during his latest trip to Pyongyang on Tuesday. "That was a big problem, and I think it's going to work out well".
Early Thursday, Trump personally welcomed three freed Americans returning home from North Korea, declaring, "We're starting off on a new footing" with Pyongyang.
Pompeo implied that the Trump administration would not seek to overthrow Kim if he surrendered his nuclear stockpile.
After the end of the Korean war in 1953 the South, an ally of the USA, embraced a capitalist philosophy. The details of denuclearization will be discussed then between the two leaders.
