North Korea cancelled a meeting with Mike Pence during the Olympics, according to the White House

US vice president Mike Pence was all set to hold a history-making meeting with North Korean officials during the Winter Olympics in South Korea, but Kim Jong Un's government cancelled at the last minute, the Trump administration has said.

A potential meeting between Mr Pence and the North Koreans had been the most highly anticipated moment of the vice president's visit to Pyeongchang, South Korea, where he led the US delegation to the opening ceremonies.

Ahead of the visit, Trump officials had insisted they had requested no meeting with North Korea, but notably left open the possibility one could occur.

There was no indication that a meeting had indeed been planned - and then cancelled on short notice - until Tuesday, more than a week after Mr Pence returned to the United States.

The State Department said Mr Pence had been "ready to take this opportunity" but would have used it to insist Pyongyang abandon its nuclear weapons and ballistic missile programs.

"At the last minute, DPRK officials decided not to go forward with the meeting," said State Department spokeswoman Heather Nauert, using an acronym for the North's formal name, the Democratic People's Republic of Korea. "We regret their failure to seize this opportunity."

A Trump administration official said the US had expected the meeting to occur on February 10, the last day of Mr Pence's three-day visit to the Olympic Games.

The administration did not say exactly how much notice it received from North Korea that the meeting had been called off, nor where the meeting would have taken place or under what conditions

Nor was it immediately clear whether North Korea scheduled the meeting before the vice president arrived in South Korea or after he had already arrived.

The day before landing in Pyeongchang, Mr Pence told reporters that "we haven't requested a meeting with North Korea".

"But if I have any contact with them - in any context - over the next two days, my message will be the same as it was here today: North Korea needs to once and for all abandon its nuclear and ballistic missile ambitions," Mr Pence said.

North Korea had no immediate response to the news out of Washington. But North Korean officials had said previously that they had no interest or intention of meeting with Pence in Pyeongchang during the games.

A potential high-level interaction between the US and North Korea, which would have broken years of estrangement between the two countries, loomed prominently over the Winter Games, where North Korea made a last-minute move to send its athletes to compete on a combined team with South Korea, the host of the games.

Since taking office, the Trump administration has been working to increase economic pressure on the North to abandon its nuclear programs while also threatening military action, insisting at the same time that a diplomatic solution would be preferable for all sides.

Yet for months the Trump administration had offered inconsistent messages about what conditions would be needed for a tete-a-tete - such as whether North Korea would have to agree that its nuclear program was on the table before the United States would be willing to sit down.

Mr Pence's office, acknowledging the scrapped meeting on Tuesday, said North Korea had "dangled a meeting" in hopes that doing so would entice the vice president to ease up on the North. Pence's office suggested that North Korea later bailed because it became clear he would hold firm on the US stance if a meeting did occur.
