The U.S. says its policy toward North Korea is not aimed at hostility but rather at ultimately achieving the complete denuclearization of the Korean Peninsula.
While talking with ABC News on Sunday, the U.S. National Security Advisor Jake Sullivan said Washington was prepared to engage in diplomacy with Pyeongyang and ready to work on "practical measures " to achieve denuclearization.
His remarks come shortly after North Korea on Sunday said U.S. President Joe Biden made a 'big blunder' in his first congressional address last week, adding that his remarks indicate a "hostile" policy.
Kwon Jong-gun, director general of the U.S. affairs department at the North's foreign ministry said Biden's policy is now clear, so the North will have to take "corresponding measures," and with time the U.S. will find itself in a "very grave situation."
He also warned that Washington will face a crisis "beyond control" if it approaches North Korea from what he called an outdated perspective.
In Wednesday's presidential speech to Congress, the U.S. President singled out North Korea and Iran's nuclear programs as serious threats to world security.
"On Iran and North Korea, nuclear programs present serious threats to American security and the security of the world. We're going to be working closely with our allies to address the threats posed by both of these countries through diplomacy as well as stern deterrence."
A separate statement on Sunday also accused the U.S. of engaging in "political chicanery" last week, when the U.S. State Department called North Korea "one of the most repressive and totalitarian states in the world."
Experts say that the series of statements from Pyeongyang is a way for the North to try and gain leverage.
"North Korea released the two statements today to put pressure on the United States in order to get what they want. They demand and request the withdrawal of this hostile policy first, but it seems to me that there is no kind of effort by the Biden administration to withdraw any kind of hostile policies."
Earlier, on Friday, Biden's press secretary, Jen Psaki said the U.S. had completed a months-long review on North Korea and plans to pursue a "calibrated, practical approach" that differs from the two previous administrations.
