A senior North Korean official has described US Vice-President Mike Pence remarks as “stupid”, putting further doubt about a planned meeting between the two countries’ leaders.
Choe Son-hui said Pyongyang would not “beg” for dialogue and warned of a “nuclear showdown” if diplomacy failed.
In recent days, both sides have said that the 12 June Trump-Kim summit could be delayed or even called off.
Pyongyang has insisted it would not give up nuclear weapons unilaterally.
US President Donald Trump on Tuesday said that it was the North that had to meet the conditions for the talks to go ahead.
‘Impudent’
Choe Son-hui has been involved in several diplomatic interactions with the US over the past decade.
Her latest comments came days after Mr Pence warned that North Korea “may end like Libya” – where then-leader Muammar Gaddafi was killed by rebels in 2011 after renouncing nuclear weapons eight years earlier.

In an article carried by the state news agency KCNA on Thursday, Ms Choe said Mr Pence had made “unbridled and impudent remarks”.
She added: “As a person involved in US affairs, I cannot suppress my surprise at such ignorant and stupid remarks gushing from the mouth of the US vice-president.
“Whether the US will meet us at a meeting room or encounter us at nuclear-to-nuclear showdown is entirely dependent upon the decision and behaviour of the United States.”
US National Security Adviser John Bolton also angered North Korea last week by saying it could follow a “Libya model” of verifiable denuclearisation.
That led to North Korea’s vice-foreign minister threatening to pull out of the Trump-Kim summit.
Meanwhile North Korea is pressing ahead with plans to dismantle its only nuclear testing facility later this week.
The Punggye-ri site is located in a remote part of the north-west of the country. A group of international journalists, who have been invited to observe the event, are on their way there.
