TURNBERRY, Scotland — The United States and European Union struck a trade agreement on Sunday locking in a 15 percent tariff, days before Donald Trump’s deadline to do a deal or face tariffs double that level.

Trump, speaking after meeting European Commission President Ursula von der Leyen at his Turnberry golf club in Scotland, announced the deal to U.S. reporters.

“This is the biggest one of them all,” Trump said after a meeting that lasted around an hour.

Von der Leyen, who flew in at short notice to meet Trump, said: “It was heavy lifting we had to do. But many thanks also for the talks we had many times on the way to our goal, but now we made it.”

Trump, reading from a paper, said the EU will agree to purchase $750 billion of energy. It will also agree to invest $600 billion more than planned in the U.S., in military equipment and in opening countries to trade at zero tariff.
