"No more rocket launches, nuclear testing or research!" "The hostages are back home with their families".
"And he also thanked Kim, saying their "day together was historic".
Pompeo, who flew to Seoul to brief South Korean leaders, said the brief, four-point joint statement that emerged from the summit did not encapsulate all the progress the USA and North Korea had made. Despite President Trump saying they would remain in place.
He said that Kim is "very smart" and a "good negotiator".
Trump's tweets pointed to one of the chief gains at the summit from the United States point of view - that its scheduling and the establishing of a relationship between the President and Kim have eased fears that the two sides are on a slide toward a disastrous war. The president also criticized the other G-7 countries as taking advantage of the U.S.
"At the same time, we believe North Korea's reasonable security concerns should be resolved". The two sides promised to hold follow-up negotiations.
Meanwhile, both countries were optimistic on developments with the North Korean regime following President Trump's summit with North Korean leader Kim Jong Un.
Following the summit, Trump told reporters during a news conference in Singapore that Kim agreed to "destroying a major missile engine testing site" and that it would be done "very soon", without elaborating further on which testing site or timing.
The move - long demanded by Pyongyang - has been seen as a major concession to North Korea and appeared to take U.S. allies in the region by surprise.
Pompeo's comments came after North Korean state media reported on Wednesday that Trump had agreed to a "step-by-step" process, suggesting that North Korea would gain concessions from the USA at the same time.More news: Trump's trade adviser apologizes for saying Trudeau has 'special place in hell'
Trump said that as much as he "hated" to use violent rhetoric against Kim several months ago, "without the rhetoric, we wouldn't be here".
South Korean ambassador Baeksoon Lee also said Mr Trump's "bold, top-down leadership" had made this week's landmark Singapore summit possible, heralding a "new chapter of history" that will need to be backed up with concrete and verifiable steps towards North Korean denuclearisation.
The post-summit transformation of North Korea's official version of Trump, who's now being shown by state media looking serious and nearly regal, underscores the carefully choreographed reality show the government has had to perform to keep its people, taught from childhood to hate and distrust the "American imperialists", ideologically on board with the tectonic shifts underway in their country's relationship with Washington. At his news conference, Trump said the war games were expensive, provocative and inappropriate. "We have not spoken in depth about this topic between the three foreign ministers today", Kang said.
Trump struck an optimistic tone about his talks with Kim. The self-proclaimed master of the art of the deal may have concluded in the first few minutes of his meeting with Kim that the outcome would be successful.

USA officials said it was unclear what types of training involving US and South Korean troops might cross into Trump's now forbidden zone of "war games".
When asked about thousands of people imprisoned in labor camps, Trump said he thinks he has helped them because things in North Korea will change. And about eight of their representatives were watching it, and I thought they were fascinated.

"Otto did not die in vain".
"There are a lot of killers", Trump said.
Pompeo insisted North Korea was committed to giving up its nuclear arsenal but said it would "be a process, not an easy one".
Trump said he would "absolutely" invite Kim to visit the White House and is open to visiting Pyongyang, as well. USA defence analysts have said Kim retains as many as 60 nuclear bombs and a range of missiles, including some he says can strike the US. Kono, Abe's foreign minister, said the government wasn't considering such a meeting at the moment and that high-level exchanges must resolve the issue of Japanese abductees held by North Korea.
