Discrepancies between the two sides' version of the deal have emerged, and key details of the agreement are yet to be negotiated.

While Trump and European Commission President Ursula von der Leyen announced a deal this week for U.S. tariffs of 15% on most imported EU goods - half the initially threatened 30% - that is still 10 times higher than the average tariff on EU imports before Trump's return to the White House.

U.S. President Donald Trump's recent executive order only sets out his so-called "reciprocal" tariff for the EU at 15% and does not apply to cars and other agreed carve-outs, EU officials said on Friday,

European wine and spirits will face a 15% U.S. import tariff until a different deal is agreed in talks expected to continue in the autumn, the European Commission and EU diplomats said on Thursday, dashing producers' hopes of an immediate reprieve.
