Still, Trump added he is “the only one” who can get Kim “where you have to be”, and is urged Kim to “act quickly, get the deal done”.

He also hinted at another meeting, writing, “See you soon!”

Meanwhile, North Korea on Sunday ruled out any denuclearisation talks with the US unless Washington lifts its “hostile policies” against the regime, according to country’s state-run media.

“Even if talks between North Korea and the US occur in the future, we will never discuss the nuclear issue unless the US first puts forth proposals to withdraw its hostile policies against us, with an aim to improve our relations,” the Korean Central News Agency reported on Sunday, citing a foreign ministry spokesman.

US and South Korea postpone joint warplane drill blasted by North Korea

The statement, made in response to the United Nations’ adoption of a resolution on North Korea’s human rights conditions last week, came hours after the US and South Korea announced they would postpone a joint military training exercise this month as part of diplomatic efforts.

Pyongyang earlier blamed the drills “as a main factor of screwing up tensions” and reminded Washington that Kim had given the US a year-end deadline to reduce sanctions or “face a greater threat”.

While Washington’s willingness to adjust the drills has helped thaw tensions, the UN resolution was “a clear reminder” that the US has yet to give up its purpose of “tearing down our regime”, according to KCNA.

“That the US is still dreaming about overturning our regime even as bilateral talks are being touted proves that it has no intention to sincerely sit down with us to resolve the issue,” KCNA said. “We are no longer willing to sit down with it either.”

Pyongyang’s decision to make the statement despite the postponement of the joint drills “seems to suggest a difficult road ahead of resuming a dialogue on denuclearisation, said Rachel Minyoung Lee, an analyst at NK Pro in Seoul.
