North Korean state media brushed over the failure to reach a deal in its coverage of the Vietnam summit between Donald Trump and Kim Jong-un, indicating that hope remains for progress in future negotiations.

The headline on the front page of Rodong Sinmun, the country's official newspaper, made no mention of the collapse in talks and the lack of agreement, instead proclaiming how well the summit had gone.

The newspaper referred to the "constructive and candid exchange" that the US and North Korean leaders had during their two days of meetings in Hanoi, the Vietnamese capital.

The positive write-up was noted by US officials, who took heart from the fact that North Korea appeared to be playing down the rift rather than returning to the bellicose rhetoric common before the recent thawing in relations.

Mike Pompeo, the US Secretary of State who had been by Mr Trump's side for much of the talks, said he was "anxious" to return to the negotiating table in a conversation with reporters during a trip to the Philippines.
