North Korea warned the US on Sunday that it will "find itself in a very grave situation" after comments made by President Joe Biden earlier this week, the Associated Press reported.
During Biden's first address to a joint session of Congress on Wednesday night, he said that the nuclear programs in North Korea and Iran "present a serious threat to America's security and world security."
The president added that he would work with allies to address these threats through "diplomacy and stern deterrence."
A top North Korean official, however, has denounced Biden's words as a "big blunder."
"His [Biden's] statement clearly reflects his intent to keep enforcing the hostile policy toward the Democratic People's Republic of Korea (DPRK) as it had been done by the US for over half a century," Kwon Jong Gun, a senior North Korean Foreign Ministry official, said in a statement published by North Korean news agency KCNA.
"It is certain that the US chief executive made a big blunder in the light of the present-day viewpoint," Kwon continued. "We will be compelled to press for corresponding measures, and with time the US will find itself in a very grave situation."
Kwon's comments follow White House press secretary Jen Psaki outlining the Biden's administration's "calibrated, practical approach" to North Korea on Friday.
Psaki told reporters on Air Force One that the US had completed its review of US policy towards North Korea, Axios reported.
"Our goal remains the complete denuclearization of the Korean Peninsula with a clear understanding that the efforts of the past four administrations have not achieved this objective," Psaki said, the Associated Press reported.
