U.S. President Joe Biden is committed to ending North Korea's nuclear program but the reclusive nation says it isn't threatened by western warnings.
Its foreign ministry Sunday released statements in response to the Biden administration's comments on denuclearization.
Director general of the North Korean foreign ministry's U.S. affairs department, Kwon Jong Gun, said Biden's policy speech to Congress last week discussing North Korea's nuclear program was "a big blunder."
Kwon said Biden's promise to intervene would compel Pyongyang to press for corresponding measures and "with time the U.S. will find itself in a very grave situation."
Kwon said Biden's statement clearly reflected Washington's goals of "enforcing the hostile policy against (North Korea)."
International analysts believe Pyongyang will move to provoke the U.S. In late March, the isolated country launched two short-range ballistic missiles into the Sea of Japan.
Japan Prime Minister Yoshihide Suga said governments around the world should be "more vigilant and watchful than ever before."
Following North Korea's latest statements U.S. National Security Adviser Jake Sullivan said Biden's policy wasn't hostile but aimed at "achieving the complete denuclearization of the Korean peninsula."
Sullivan said the administration was ready to "engage in diplomacy."
Biden is scheduled to meet South Korean President Moon Jae-in later in May.
Last week, the chiefs of staff of Japan, South Korea and the U.S. met in Hawaii to discuss North Korea and the importance of implementing international order.
In a statement after the meeting, the U.S. said all parties were concerned about North Korea's missile program.
