There has been no suggestion that North Korea sees such dialogue as a precursor to negotiations about its nuclear and weapons programme, or that it is softening on the question of denuclearisation.

Instead, officials have indicated that the regime is seeking recognition as a nuclear state.

Washington has made it clear that it is not interested in talking right now, opting to increase pressure on North Korea though increased sanctions and the threat of military action.

President Trump on Tuesday warned that the US was “fully prepared” to use “devastating” military force against Kim’s regime, although stressed it was not a preferred option.

He encouraged the world to work together to end the North Korean nuclear programme as he introduced new sanctions on the pariah nation’s banks.
