"The Department of the Treasury will be designating Wagner as a significant transnational criminal organization under Executive Order 13581 as amended," Kirby said during a press briefing.
Kirby said the US government will also impose additional sanctions next week against Wagner and its support network across multiple continents.
The US government will work to identify, disrupt, expose and target firms that are assisting the Wagner Group, the White House official said.
Designating the Wagner Group as a transnational criminal organization will open up additional avenues for the United States to continue to not only sanction Wagner but put more pressure on the company's ability to do business around the world and assist others in doing the same, Kirby added.
