He made the comment at an event in New Jersey.

North Korea slammed the penalties — which could slash a third of the country’s $3 billion in export revenue — as a “violent infringement of its sovereignty” and part of a “heinous U.S. plot to isolate and stifle” the country.

“It’s a wild idea to think the [Democratic People’s Republic of Korea] will be shaken and change its position due to this kind of new sanctions formulated by hostile forces,” the statement said.
