North Korea had also said talks would be about denuclearization, but it is not clear that Pyongyang agreed to do anything toward that end before a meeting that South Korea said would take place "by May".
USA officials asserted that a Trump-Kim meeting would hinge "on the basis that we see concrete and verifiable steps" with regard to North Korea's commitment to refrain from nuclear and missile testing.

The announcement triggered a rise in global stock markets while world leaders voiced hope that the summit would deflate tensions that had been building dramatically in recent months. President Trump would do well to understand the danger of this outcome before he meets with Kim, not afterward.
US -based experts say North Korea appeared to show last November that it has succeeded in developing a missile capable of delivering a nuclear weapon anywhere in the United States. The European Union, Russia and China - whose leader spoke by phone with Trump on Friday - have all welcomed the move.
In an unprecedented event, the White House made an announcement that President Donald Trump would meet Kim soon at a landmark summit which aims at deescalating the current nuclear standoff. Trump discussed the offer with top aides on Thursday.
The exercises are believed to include rehearsals of what is known as OPLAN 5015, in which USA and South Korean forces would carry out "decapitation" strikes aimed at killing Kim and other senior members of his regime. North Korea is also holding three American citizens for what Washington views as political reasons.
Volo said that Kim asked Rodman about Trump before he announced his candidacy for president and "he had a lot of respect for the future president at the time".

South Korea's Yonhap news agency quoted a government official as saying National Security Office chief Chung Eui-yong conveyed the message to Trump on Thursday. After a year of tough talk, Trump, who before entering the White House had little foreign policy experience, will be sitting down in one of the most politically fraught discussions of his presidency and some hawks warn Trump needs ground rules first.
"Our assessment was that the North Koreans weren't serious about denuclearisation and therefore sitting down to a summit just accords legitimacy.to the regime, not just the leader, without achieving any concrete national security objective for the United States", said Michael McFaul, US ambassador to Russian Federation under Obama.
North Korea still produces propaganda declaring its continued dedication to its nuclear program. North Korea's overall goals haven't changed: It seeks a peace treaty and normalization of relations with Washington, and in return for that and denuclearization, it wants all USA troops out of South Korea.
Analysts say that the encouraging headlines has improved risk sentiment, especially in the Asian-Pacific region with the Nikkei moving higher and gaining more than 2%.
Later in the day, Trump himself tweeted out that there was, indeed, a deal "very much in the making". "Otherwise we are setting ourselves up for a major diplomatic failure".
"While South Korea is clearly on board, so must be Japan, whose leaders must be suffering a case of diplomatic whiplash after having been Mr. Trump's biggest cheerleader in his campaign to pressure Pyongyang and consider military options".
After a brief thaw in relations during the Winter Olympics, it was thought the North Koreans might restart missile and nuclear tests with a predictable incendiary response from the US President.
