The North's official KCNA news agency said foreign ministry official Kwon Jong Gun made the comment about Pompeo. Kwon said that no one could predict what may happen if the United States did not stop the "root cause" that made North Korea develop nuclear weapons.
朝鲜官方的朝中社表示，外交部官员权正根(Kwon Jong Gun)对蓬佩奥发表了评论。权正根表示，如果美国不放弃迫使朝鲜发展核武器的“根本原因”，则没人可以预测事态发展。
Hours earlier, North Korea announced that leader Kim Jong Un had watched the testing of a new tactical guided weapon. KCNA said the weapon has a special way of guiding flight and "a powerful warhead."
It was the North's first weapon test since the February talks between Kim and U.S. President Donald Trump in Vietnam. Those talks ended without an agreement. North Korea wanted the U.S. to reduce sanctions in some way while the U.S wanted North Korea to move forward to end its nuclear program.
North Korea gave no details on the weapon that was tested on Wednesday. The word "tactical" usually describes a short-range weapon rather than a long-range missile that could threaten the U.S.
KCNA said that Kwon, who heads U.S. affairs, said the Vietnam meeting showed that talks could go wrong when Pompeo takes part. Kwon said another meeting would not be successful with Pompeo there. In any future U.S.-North Korea talks, Kwon asked that someone take Pompeo's place.
"I wish our dialogue counterpart would be not Pompeo but [an]other person who is more careful and mature in communicating with us."
A spokeswoman for the U.S. State Department said officials knew about the report and added that the U.S. is ready to take part in productive talks with North Korea.
Kwon did not explain more about why North Korea was being forced to develop nuclear weapons. North Korea has for many years said it needs to defend itself from what it considers U.S. aggression.
Last week, Kim Jong Un said the failure of the talks could cause new problems between the two countries. He said the U.S. must change its methods by the end of the year.
However, Trump says he has a good relationship with Kim.
Kwon also said the two leaders were on good terms. At the same time, he criticized Pompeo for telling untrue stories to get attention. He did not explain.
Kwon said Pompeo had said things to dishonor North Korea's leader. Last week, Pompeo agreed to the naming of Kim as a "tyrant" at a U.S. congressional hearing.
Not all Kim's weapons are nuclear
Kim Dong-yub is a military expert at Kyungnam University's Institute of Far Eastern Studies in Seoul. He said the newly tested weapon was likely a cruise missile that could be launched from the ground, sea or air.
Harry Kazianis works with the Center for the National Interest in Washington. He said, "Chairman Kim Jong Un never promised to stop testing all weapons in his military arsenal." Last April, Kim said that he would stop nuclear tests and launches of intercontinental ballistic missiles (ICBMs). They are long-range missiles that could reach the U.S.
U.S. forces did not see a missile launch from North Korea.
