North Korea’s top diplomat lashed out at President Trump on Wednesday, saying US threats against the kooky hermit kingdom are no more than “the sound of a dog barking.”

Foreign Minister Ri Yong-ho, in New York for the UN General Assembly, dismissed Trump’s vow to “totally destroy” North Korea if Pyongyang ever posed a direct threat to America.

“If he was thinking he could scare us with the sound of a dog barking, that’s really a dog dream,” Ri told reporters outside his hotel.

Ri was invoking a Korean proverb that says a procession will keep moving forward, even if a dog is barking at it, according to the Yonhap news agency. He also employed a Korean idiomatic phrase, a “dog dream,” which is one that makes no sense.

Asked if he had any reaction to Trump’s mockery of North Korean dictator Kim Jong Un as “Rocket Man,” Ri said: “I feel sorry for his aides.”

Ri is scheduled to speak to the world body Friday.

Global leaders are becoming increasingly worried about North Korea’s nuclear aspirations as the country continues to test-fire missiles over US ally Japan.
