The White House said China is now facing up to a 245 percent tariff on imports to the U.S. “as a result of its retaliatory actions,” another escalation in a trade war between the world’s two largest economies.

The top potential tariff is higher than the previously stated 145 percent and was referenced in a fact sheet published by the White House late on Tuesday.

It accompanied an executive order signed by President Donald Trump that launched an investigation into the “national security risks posed by U.S. reliance on imported processed critical minerals and their derivative products.”
