"I'm very committed to working with the North Korean team to negotiate a set of outcomes that will be good for both the United States and the world in terms of reducing the nuclear threat that emanates from the Korean Peninsula, but also ensuring that security and peace and prosperity can come to North Korea as well," the top US diplomat said.

Asked to assess North Korea's commitment to the talks, given its series of short-range ballistic missile launches since late July, Pompeo was still hopeful.

"We think they're still committed. We think they're still -- intend to head down the diplomatic path, and we're doing everything we can to encourage that, because we think it's the right outcome for the world," he said.

Talks broke down after Trump and Kim's second summit in Vietnam in February ended without a deal. The North Koreans had asked for more sanctions relief than the US was willing to give for Pyongyang's offer to dismantle only its main nuclear complex in Yongbyon.

Aside from sanctions relief, the North has also made clear that it seeks security assurances from the US.

On Wednesday, Trump appeared to address that concern by stating that the US is not looking for a regime change in North Korea or Iran.

Pompeo added that the North has a right to self-defense, touching on an argument the regime has often used to justify its ballistic missile tests that are banned by UN Security Council resolutions.

"Those nuclear weapon systems that North Korea has been driving towards for decades now don't provide the security that the North Koreans believe they do," he said in the interview. "In fact, what will provide them security is coming to a set of understandings with the United States and with the world to denuclearize. And when they do so, we'll provide the security assurances that are needed for them and for their people. Every nation has the sovereign right to defend itself. Then we can create economic opportunity and better lives for the people of North Korea as well."

The remarks come after North Korean officials slammed Pompeo for calling out North Korea's "rogue behavior" and suggesting that all sanctions on the country will remain in place short of its denuclearization.

Vice Foreign Minister Choe Son-hui said last week that hopes for the negotiations are "gradually disappearing." (Yonhap)
