Stocks were mixed in early trading on Monday after President Donald Trump over the weekend issued 30% tariffs on the European Union and Mexico, rekindling tensions with two of the largest U.S. trade partners and threatening to raise consumer prices.

The European Union’s top trade negotiator has signaled the bloc will continue trying to reach a deal with the U.S. after President Donald Trump threatened a 30% tariff on goods from the bloc and Mexico over the weekend.

“Trump is trying to divide and scare Europe, but if we raise our heads now, there will be division in the American camp, even among his most important supporters, because many companies in key electoral districts would be damaged by our response,” Benifei said in the interview.
