China on Wednesday named Li Chenggang as vice minister of commerce and the new international trade negotiation envoy amid an ongoing trade war with the United States.

China has appointed a new trade negotiator in the midst of its tariff fight with the United States as the world’s two largest economies steadily increase tariffs on each other’s goods.

China is now looking at U.S. tariffs that could go as high as 245%, a jump linked to what the White House called retaliatory actions from Beijing. The new figure showed up in an April 15 fact sheet tied to an ongoing review into the national security risks of relying on foreign critical minerals.
