North Korea's foreign ministry said in an article published on Thursday that the United States' offer was a plot to water down international criticism on its hostile policy toward North Korea.

The ministry criticized the United States' offer of humanitarian aid to be insincere amid its recent military exercises and moves to impose more sanctions.

It added that the United States, which failed on its own COVID crisis, should drop its "foolish" offer, and take care of its own situation at home.

Washington and South Korea had offered to provide humanitarian support, such as COVID vaccines and medical supplies, to North Korea after its first COVID outbreak since late April, but got no responses from Pyongyang.
