BRUSSELS — President Donald Trump warned the European Union on Thursday that the United States would act to restrict entry for European light vehicles if the bloc failed to treat America fairly on trade.

Trump, who is set to host European Commission President Jean-Claude Juncker in Washington this month, repeated his line that the EU was treating the United States unfairly on trade, shutting out U.S. farmers.

“That’ll change also and I think we’ll see that because on the 25th of July they’re coming in to start negotiations with me. We’ll see,” he told a news conference at the end of a meeting of NATO leaders.

“And if they don’t negotiate in good faith we’ll do something having to do with all the millions of cars that are coming into our country and being taxed at a virtually zero level, at a very low level… I think it’s been a very effective way of negotiating, but I’m not negotiating, I just want fairness for the United States,” he said.

Trump has ordered U.S. agencies and regulators to explore the feasibility of tariffs on imported light vehicles based on national security concerns. The review has sparked strong opposition from automakers and suppliers.
