North Korea has said it may pull out of a summit with US President Donald Trump if the US insists it gives up its nuclear weapons.
The highly anticipated meeting between Mr Trump and North Korea’s Kim Jong-un is due to take place on 12 June.
North Korea’s vice-foreign minister in an angry statement accused the US of making reckless statements and of harbouring sinister intentions, thereby directly blaming the US National Security Adviser John Bolton.
The groundbreaking agreement for Mr Kim and Mr Trump to meet came about as North Korea said it was committed to denuclearising the Korean peninsula.
Mr Bolton recently said North Korea could follow a “Libya model” of verifiable denuclearisation, but Pyongyang has in the past suggested that Libya may have escaped Western military intervention in 2011 had it kept its nuclear weapons programme.
