North Korea is saying it will reconsider a summit with President Donald Trump if the U.S. continues with what it calls "evil acts."
Pyongyang was reacting to comments by Vice President Mike Pence who appeared on Fox News Monday to warn Kim Jong Un he would be making a "great mistake" to play around with the United States before the talks.
Pence also said North Korea could wind up like Libya if Kim does not make a deal.
Libya has been in political and social turmoil since it gave up its nuclear ambitions and its longtime dictator Moammar Gadhafi was killed.
North Korea's Vice Foreign Minister Choe Son Hiu made no attempt to soften her government's offense, calling Pence's words "unbridled and impudent."
"As a person involved in U.S. affairs, I cannot suppress my surprise at such ignorant and stupid remarks gushing from the mouth of a U.S. vice president," the state run news agency reported Thursday.
Choe also hinted that the North does not need a summit with Trump. "We will neither beg the U.S. for dialogue nor take the trouble to persuade them if they do not want to sit together with us."
Trump said Wednesday the U.S. will know by next week whether he will meet with Kim on June 12 in Singapore as scheduled.
