North Korea has threatened to withdraw from the summit with United States President Donald Trump if America insists it gives up all its nuclear weapons.
The highly anticipated meeting between North Korea's Kim Jong-un and Trump is scheduled to take place on 12 June in Singapore.
The deal between America and North Korea came about as North Korea said it was dedicated to denuclearising the Korean peninsula. It remains uncertain what that would entail but North Korea has invited outside media to witness the demolition of its main nuclear test site later this month.
But recently, North Korea's vice-foreign minister Kim Kye-gwan has accused America of making harsh remarks and harbouring sinister intentions. He pointed the finger at John Bolton, the US National Security Adviser John Bolton.
"We do not hide our feeling of repugnance towards him," Kim Kye-gwan said.
Bolton recently said North Korea could follow a "Libya model" of verifiable denuclearisation. The then-Libya's Colonel Gaddafi gave up his nuclear programme only for him to be killed by Western-backed rebels a few years later.
Kim Kye-gwan said North Korea was expectant but it's unfortunate that the US is provoking them ahead of the summit by making ludicrous statements."
North Korea has suspended all missile tests, released the three US hostages, Mr. Kim met South Korean president Moon and the duo signed a declaration. Now they are about to dismantle a nuclear test site with international media present.
So to hear the Trump administration taking credit for a deal they don't like is a step too far.
