US says NKorea threat 'deeply disappointing' but 'wants peace'

The United States is deeply disappointed by North Korea's threat to resume nuclear missile tests but wants peace rather than confrontation with Pyongyang, Secretary of State Mike Pompeo has said.

"If Chairman Kim has reneged on the commitments he made to President Trump it's deeply disappointing," Pompeo said after North Korean leader Kim Jong-un declared an end to moratoriums on nuclear and intercontinental ballistic missile tests.

"We have lived up to our commitments. We continue to hold out hope that he will live up to his," the top US diplomat told CBS television.

"President Trump has taken an approach where we have tried to create a diplomatic pathway. We hope that the North Koreans will reconsider, that they will continue down that pathway.... We want peace not confrontation."
