TURNBERRY, Scotland, July 27 (Reuters) - The U.S. struck a framework trade agreement with the European Union on Sunday, imposing a 15% import tariff on most EU goods - half the threatened rate - and averting a bigger trade war between the two allies that account for almost a third of global trade.

The deal, announced Sunday by President Trump and European Commission President Ursula von der Leyen, imposes a 15% U.S. tariff on most EU imports, while American goods exported to the union's 27 member countries will face no tariffs. Previously, U.S. exports to the EU faced an average tariff of roughly 1%, according to Goldman Sachs analysts.

Trump said the U.S. will impose a 15% tariff on Japanese imports under the agreement, which he hailed as "maybe the largest deal in history."
