The Chinese Embassy is calling on the U.S. to "immediately correct its mistake" of imposing fresh unilateral sanctions on Chinese companies over their alleged support of North Korea's nuclear and ballistic weapons programs.

"China opposes unilateral sanctions out of the [United Nations] Security Council framework, especially the 'long-arm jurisdiction' over Chinese entities and individuals exercised by any country in accordance with its domestic laws," a spokesman said Tuesday, as reported by Reuters.

"We strongly urge the U.S. to immediately correct its mistake, so as not to impact bilateral cooperation on relevant issues."

The spokesman's comments came hours after the Trump administration announced new sanctions on Chinese and Russian businesses and individuals charged with helping North Korea bolster its weapons programs.

The penalties mark the latest effort by the Trump administration to increase pressure on China to help rein in Pyongyang's efforts to develop nuclear weapons and intercontinental ballistic missiles.
