Kate Hudson, CND general secretary, said:

“It is regrettable that today’s talks have stalled, but it is good news that relations between the US and North Korea don’t appear to be returning to the dangerous tensions of 2017.

“There is clearly the potential for further talks. Though it remains to be seen how the US President who has spent the last year weakening and tearing up crucial arms control treaties can make diplomacy work on the Korean peninsula.

“The US withdrawal from the Iran nuclear deal and the expected ending of the Intermediate-Range Nuclear Forces Treaty is not a strong foundation for a new era of diplomacy.”
