Trump and Kim have met three times to try to reach a deal on denuclearizing North Korea in exchange for US concessions, but negotiations have stalled due to wide gaps over how to match their steps.

Kim also said in his remarks before a key ruling party meeting that he sees no reason to continue his self-declared moratorium on nuclear and intercontinental ballistic missile tests.

Trump has repeatedly held up the absence of such tests as an outcome of his diplomatic engagement with Kim.

"We hope that the North Koreans will reconsider," Pompeo said in an interview with CBS. "If Chairman Kim has reneged on the commitments he made to President Trump, that is deeply disappointing. I was there when Chairman Kim made the commitment that said he would not engage in intercontinental ballistic missiles or test-firing of their nuclear weapons, testing their nuclear weapons systems. He made those commitments to President Trump in exchange for President Trump agreeing not to conduct large-scale military exercises. We've lived up to our commitments.

We continue to hold out hope that he'll live up to his as well." (Yonhap)
