South Korea described the breakdown of nuclear talks between President Donald Trump and North Korean leader Kim Jong Un on Thursday as unfortunate, but expressed hope that the two countries can continue an active dialogue.
"Speed's not that important to me", he said as he began talks with Mr Kim at the Sofitel Legend Metropole hotel on Wednesday.
"No agreement was reached at this time, but their respective teams look forward to meeting in the future", said White House spokeswoman Sarah Sanders, confirming cancellation of a ceremony to sign a joint agreement.
Mr Kim called the U.S. president "courageous" in return and said he was confident there would be an "excellent outcome that everyone welcomes".
He made little mention of denuclearisation in his opening remarks, ramping down expectations further by saying "I can't speak necessarily for today but... over a period of time I know we're going to have a fantastic success with respect to Chairman Kim and North Korea".
The United Nations and the USA tightened sanctions on North Korea after a flurry of nuclear and missile tests in 2016-2017.
To this end, Kim arrived in Vietnam after a 66-hour long train journey which would only take six hours by air.
"Basically, they wanted the sanctions lifted in their entirety, and we couldn't do that", Trump told reporters.

Tonight on Left Right and Centre we ask, is Abhinandan's return enough for de-escalation or is this just a temporary hiatus. On Wednesday he pushed for talks with Delhi to prevent the risk of a "miscalculation" between the nuclear-armed neighbours.
We had a very successful first summit. "And, there were a lot of great ideas being thrown about", Trump said.
Kim said they had overcome obstacles to hold the summit in Vietnam and had needed patience since their first meeting in Singapore previous year.
The president already showed he had the testimony at the back of his mind when he tweeted about it before his first meeting with Kim, saying Cohen - who has been sentenced to three years in jail - was "lying in order to reduce his prison time".
The US side had been hoping for major progress in dismantling equipment and facilities at the main North Korean nuclear complex at Yongbyon.
Bong Young-shik, an analyst at Seoul's Yonsei University, was less anxious, saying that the criticism Trump faced in Singapore could make him less likely to make huge, impulsive decisions during his private meetings with Kim this time around.
Furthering the spirit of optimism, the leaders seemed to find a point of agreement moments later when Kim was asked if the US may open a liaison office in North Korea.
Asked whether he was confident about the prospects for a deal, Kim replied: "Well, it's too early to tell, but I wouldn't say that I'm pessimistic. He said, 'Oh, what did I get it for?'" Trump said.
Washington had previously said that North Korea had to unilaterally give up its nuclear weapons before there could be any sanctions relief.
