The announcement came on the same day North Korea said it did not want to deal anymore with US secretary of state Mike Pompeo and called for him to be replaced in denuclearisation discussions by someone “more mature”.
And it followed the news that the North had test-fired a new tactical guided weapon in what was the first launch since a summit with US President Donald Trump ended without an agreement in Vietnam in February.
While short on details of the upcoming meeting, the Kremlin announced on its website that Mr Kim, the head of the secretive state, will visit Russia in the second half of this month.
State media in North Korea claimed the weapon had “a powerful warhead”, but did not say whether it was a missile. However the word “tactical” implied a short-range weapon, and not the long-range ballistic missiles that have been seen as a threat to the US.
