Kim and Trump have met three times since June last year, but talks have been gridlocked since their Hanoi summit in February broke up in disagreement over sanctions relief, while October’s working-level talks rapidly broke down in Sweden.

Pyongyang has set Washington a deadline of the end of the year to come forward with a fresh offer, and foreign ministry advisor Kim Kye Gwan said the US was stalling while “pretending it has made progress”.

He interpreted Trump’s tweet as a signal for a new summit, he said in a statement carried by state news agency KCNA, but declared: “We are no longer interested in such talks that bring nothing to us.”

“We will no longer gift the US president with something he can boast of,” he went on, adding the North should be compensated for the “successes” that President Trump touted as his own achievements.
