North Korea threatened again on Thursday to cancel its planned summit with the United States next month, criticizing recent remarks by U.S. Vice President Mike Pence about Pyongyang's denuclearization as "stupid."

"In case the U.S. offends against our goodwill and clings to unlawful and outrageous acts, I will put forward a suggestion to our supreme leadership for reconsidering the DPRK-U.S. summit," Choe Son Hui, a senior official in charge of negotiations with the United States, was quoted as saying by state-run media.

DPRK is the acronym of the North's formal name in English, the Democratic People's Republic of Korea. North Korean leader Kim Jong Un and U.S. President Donald Trump are scheduled to hold talks in Singapore on June 12 in what would be the first-ever Pyongyang-Washington summit.

Choe's statement followed Pence's interview broadcast Monday on Fox News. In the interview, Pence said, "There was some talk about the Libyan model last week, and, you know, as the president made clear, this will only end like the Libyan model ended if Kim Jong Un doesn't make a deal."

Some U.S. officials say North Korea must agree to a "Libya-style" denuclearization process, in which Pyongyang first gives up all its nuclear weapons before receiving any benefits.

Former Libyan leader Muammar Gaddafi, who agreed to abandon his nascent nuclear weapons program in the early 2000s, was overthrown and killed after a North Atlantic Treaty Organization-led coalition intervened in support of an uprising in the northern African country in 2011.

In the statement carried by the Korean Central News Agency, Choe, a vice minister of North Korea's Foreign Ministry, derided Pence as a "political dummy" for "trying to compare the DPRK, a nuclear weapon state, to Libya that had simply installed a few items of equipment and fiddled around with them."

"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," she said.

"Whether the U.S. will meet us at a meeting room or encounter us at nuclear-to-nuclear showdown is entirely dependent upon the decision and behavior of the United States," the official added.

Trump, meanwhile, said Tuesday that Kim will not suffer the same fate as Gaddafi if he gives up his nuclear weapons.

North Korea has recently been warning that it may cancel the planned summit, lambasting ongoing joint military drills by South Korea and the United States, and Washington's call for Pyongyang to unilaterally abandon its nuclear weapons.
