South Korea's president has welcomed North Korea's decision to dismantle its nuclear test site, calling it a start to its nuclear disarmament.
Pompeo, who met with Kim extensively on two trips to Pyongyang in recent months, separately told CBS that the U.S. won't give North Korea "a bunch of money" only to have nothing to show for it.
The secretary of state recently returned from a trip to Pyongyang, where he met with the North Korean leader.
The dismantling of the nuclear test site in the DPRK is set to take place ahead of a major summit meeting between President Donald Trump and the North Korean leader next month.
His move to prioritize economic growth has ended the imminent threat of war, and his summits with Xi and South Korean President Moon Jae-in produced pledges of economic cooperation from both leaders.

But beyond that, he is trying to encourage what he sees as a potentially significant change in attitude from North Korea, something he apparently doesn't see emerging from Iran. Bolton didn't specify whether he expects the nuclear weapons to eventually be stored at Oak Ridge National Laboratory - where the US Department of Energy operates a research lab and a nuclear weapons complex - or the nearby Y-12 National Security Complex, normally tasked with nuclear weapons production. Trump wrote in a tweet Saturday evening.
It seems clear that, from Mr Trump's perspective, the Iran deal and the diplomatic advances with North Korea are closely related - and that his policy of "maximum pressure" is paying off.
Trump is already tweeting about complete "denuclearisation", whereas North Korea has indicated it is, at best, committed now to a pause in its nuclear programme as it prepares to assess what the United States brings to the table. He was sentenced in April 2016 to 10 years in prison with hard labor for allegedly "perpetrating state subversive plots and espionage against" North Korea.
US Secretary of State Mike Pompeo said on Sunday the US will provide security assurance to North Korea's top leader Kim Jong-un, if the country could achieve denuclearisation.
"One of the most powerful things that I saw was out in the countryside - it's spring, they're planting - there's not mechanization, you've got oxen pulling ploughs, men and women in the fields", he said.
"I really think he wants to do something and bring the country into the real world", he added of Kim.
