Pompeo said a US-led sanctions pressure campaign on Pyongyang would not be eased until North Korea gives up nuclear weapons.
And if North Korea truly has completed its nuclear program, as it says it has, then it no longer needs an active test site anyway. "If we can get the two to agree that that's the end state we're working for, we will have a good day".
North Korea's last-minute acceptance of South Korean reporters came amid concerns that Kim was starting to back away from his promise to scrap the nuclear program, which it has pursued in defiance of years of UN Security Council resolutions.
U.S. Secretary of State Mike Pompeo said here on Wednesday that a "bad deal" with the Democratic People's Republic of Korea (DPRK) is "not an option" for the United States. "If the right deal is not on the table, we will respectfully walk away".
Appearing before the House foreign affairs committee, Pompeo was asked repeatedly about his two recent meetings with the North Korean leader and what the USA meant by the denuclearisation of the Korean peninsula, a goal that both parties share but which is vaguely defined.
The cancellation of a meeting between American and North Korean officials in Singapore a few weeks ago may have something to do with President Donald Trump's change of posture on the summit with North Korean leader Kim Jong Un. "A number of discussions have taken place below the foreign minister level", Pompeo said.
Emboldened by the surprise release of three Korean-Americans held in Pyongyang earlier this month, Trump boasted about the prospect of an unprecedented summit between the sitting USA president and the North Korean leader in Singapore on June 12.

Yet ahead of a bilateral meeting with South Korean President Moon Jae-in-who met Kim for the first time on April 27-Trump cast doubt over the prospect of the summit happening at all.
"That decision will ultimately be up to Chairman Kim", he said.
He said he intends to meet with allies in June to discuss next steps to stop what he described as all of Tehran's nuclear and non-nuclear threats.
On the other hand, Secretary of State Mike Pompeo adopted a more positive stance by stating that the U.S. is continuing their preparations as the summit is going to happen.
It would be historic as no sitting USA president has ever met a North Korean leader.
South Korea's Unification Ministry says the journalists were finally accepted by the North Wednesday through a message sent by a cross-border communication channel at the truce village of Panmunjom.
However, Pyongyang's professed commitment to "denuclearisation" is likely to differ from Washington's demand for "comprehensive, verifiable and irreversible" nuclear disarmament.
