I’m thinking there is a disconnect between what Trump thinks he agreed to and what Kim agreed to. This is an excerpt from an KCNA article today:
‘Noting that the building of lasting and durable peace-keeping mechanism on the Korean Peninsula is of weighty significance in ensuring peace and security in the region and the rest of the world, he said that it is urgent to make bold decision on halting irritating and hostile military actions against each other.
‘Expressing his understanding of it, Trump expressed his intention to halt the U.S.-south Korea joint military exercises, which the DPRK side regards as provocation, over a period of good-will dialogue between the DPRK and the U.S., offer security guarantees to the DPRK and lift sanctions against it along with advance in improving the mutual relationship through dialogue and negotiation.
‘Kim Jong Un clarified the stand that if the U.S. side takes genuine measures for building trust in order to improve the DPRK-U.S. relationship, the DPRK, too, can continue to take additional good-will measures of next stage commensurate with them.’
The extra bolding is mine. It would seem, though, that NK are expecting sanctions to be lifted as they “take their genuine measures for building trust”. This is not what Trump said in his presser; just the opposite.
