A top North Korean diplomat said Saturday that expectations for talks with the United States are fading away, bristling strongly at U.S. Secretary of State Mike Pompeo's description of Pyongyang's behavior as "rogue."

First Vice Foreign Minister Choe Son-hui also warned the U.S. not to test Pyongyang's patience, claiming that Pompeo's remarks made the resumption of working-level negotiations between the two countries more difficult.

"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 in a statement carried by the North's official Korean Central News Agency (KCNA).

"We are very curious about the background of the American top diplomat's thoughtless remarks and we will watch what calculations he has. The U.S. 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 afterwards," she said.

On Tuesday, Pompeo said in a speech to American veterans that the North's "rogue behavior could not be ignored" and the U.S. has "galvanized global support to denuclearize North Korea."
