A senior North Korean diplomat on Saturday berated US Secretary of State Mike Pompeo over his comments describing North Korean behaviour as “rogue” and said Pyongyang’s hopes for talks with Washington are fading.

In a statement carried by state media, North Korean First Vice Foreign Minister Choe Son Hui said Pompeo’s “thoughtless” comments increased North Korean people’s animosity toward Americans and made it harder for working-level nuclear negotiations between the countries to resume.

“Our expectations of dialogue with the U.S. are gradually disappearing and we are being pushed to reexamine all the measures we have taken so far,” Choe said.

“We are very curious about the background of the American top diplomat’s thoughtless remarks and we will watch what calculations he has.

The US had better not put any longer our patience to the test with such remarks irritating us if it doesn’t want to have bitter regrets afterward.” Pompeo in speech to US veterans in Indiana on Tuesday said the Trump administration recognized that “North Korea’s rogue behavior could not be ignored” while touting its approach in foreign policy.

“Americanism – it means telling the truth about the challenges we face,” Pompeo said. “Look, this administration didn’t pretend that the Islamic Republic of Iran was a responsible actor in the Middle East. We called out China’s bad behavior on trade and on national security. We recognized – we recognized that North Korea’s rogue behavior could not be ignored.”

Nuclear negotiations have been at a standstill since a February summit between President Donald Trump and North Korean leader Kim Jong Un in Vietnam collapsed after the US side rejected North Korean demands for broad sanctions relief in exchange for a partial surrender of its nuclear capabilities.
