At an impromptu meeting at the inter-Korean border on June 30, US President Donald Trump and North Korean leader Kim Jong-un agreed to resume the working-level talks that had stalled after their second summit in Vietnam in February ended without a deal.

Trump and Pompeo earlier said the talks would restart in mid-July, but last week the North warned it would be contingent on whether South Korea and the US conduct joint military exercises scheduled for next month.

Pompeo said in the interview that what is more important than the day is how prepared each side will be to produce results.

The real objective, he said, is "to make sure that we've had enough conversations so that there can be productive dialogue when the teams get together."

"If it takes us another two weeks or four weeks, so be it," Pompeo said. "We remain convinced that there's a diplomatic way forward, a negotiated solution to this."

He added: "President Trump has been incredibly consistent here.

We want diplomacy to work. We want Chairman Kim to deliver on the promise that he made to President Trump, which is that he would denuclearize."

In a separate interview with Fox News on Thursday, Pompeo stressed that during the June 30 border encounter with Trump, Kim made two commitments -- to continuing a moratorium on nuclear tests and launches of intermediate-range and long-range ballistic missiles and to putting his negotiation team "back in the game."

"We're working our way towards that. I think we'll be able to pull that off in just a handful of weeks," the secretary said according to a transcript from the State Department.

Pompeo also appeared to be downplaying the North's latest moves to escalate tensions.

"I think we're still going to go sit down and have a conversation about this. North Korea has engaged in activity before we were having diplomatic conversations far worse than this -- more importantly, far more dangerous for America and Japan and for South Korea than this," he said.

"I think this allows the negotiations to go forward. Lots of countries posture before they come to the table," he added.

Asked about the North Korean leader's recent inspection of a new submarine capable of carrying submarine-launched ballistic missiles, the secretary said, "I went to a defense facility. We all go look at our militaries, and we all take pictures of them."

Earlier, the State Department said it remains committed to diplomacy although it wants the North to refrain from further provocations.

"We urge no more provocations," department spokeswoman Morgan Ortagus said during a press briefing. "This administration is committed to diplomatic engagement with the North Koreans and we continue to press and hope for these working-level negotiations to move forward." (Yonhap)
