The meeting is set to take place in Singapore on June 12.

In an interview with Fox News, Pence said: "It would be a great mistake for Kim Jong-un to think he could play Donald Trump."

Meanwhile, Pyongyang was left fuming after US National Security Adviser John Bolton reportedly told media that America would follow the 'Libya model' of denuclearisation in the Korea Peninsula.

In Libya, the late dictator Muammar Gaddafi shook hands with Western powers in 2003, to allow the latter to come to his nation and dismantle his nuclear programme, in exchange of lenient sanctions.

Gadaffi was killed eight years later by the same allies-backed rebels.

According to reports, North Korea has threatened to boycott the meeting if the Trump administration unilaterally insists the former gives up nuclear weapons.

The reclusive communist nation had also stalled the much anticipated North-South dialogues, which was originally scheduled for Wednesday.

The country has cited ongoing military exercises between the South and the United States as the reason behind cancelling the meet.

"The North's Korean Central News Agency said the Max Thunder drills between the South Korean and U.S. air forces are a rehearsal for invasion of the North and a provocation amid warming inter-Korean ties," reported South Korea's Yonhap News agency. 

South Korean President Moon Jae-in is scheduled to meet Donald Trump later today at the White House, where the former is expected to discuss key points ahead of the Singapore summit.
