SEOUL, South Korea — North Korea said on Thursday that it would have second thoughts about a summit meeting between its leader, Kim Jong-un, and President Trump if American officials continued to make what the North considers threats against its leadership.

The North Korean official who issued the warning singled out Vice President Mike Pence for remarks that she called “ignorant and stupid.” In an interview broadcast on Monday on Fox News, Mr. Pence warned that North Korea’s government could end up like that of Col. Muammar el-Qaddafi, the former Libyan leader.

Mr. Qaddafi gave up his nascent nuclear program in the apparent hopes of staving off Western intervention and sanctions, and of negotiating economic integration with the West. But little of that happened, and years later he was killed by rebels after he was weakened in a military action against Libya by the United States and its European allies.

In a statement carried by the North’s official Korean Central News Agency on Thursday, the North Korean official, Vice Foreign Minister Choe Son-hui, referred to “unlawful and outrageous acts” by top American officials and said that Mr. Pence had made “unbridled and impudent remarks that North Korea might end like Libya.”
