BRUSSELS — The European Parliament voted Thursday to approve a trade deal between Washington and Brussels but with amendments added to protect European interests should the United States fail to hold up its end of the bargain.

The deal was negotiated last July in Turnberry, Scotland, by U.S. President Donald Trump and European Commission President Ursula von der Leyen. It set a 15% tariff on most goods in an effort to stave off far higher import duties on both sides that might have sent shock waves through economies around the globe.

New language now says that the deal can be suspended if Washington “undermined the objectives of the deal, discriminated against EU economic operators, threatened member states’ territorial integrity, foreign and defence policies, or engaged in economic coercion.”

That clause was forged because of the tensions over Greenland, said Bernd Lange, a German lawmaker and head of the EU’s parliamentary trade committee.

Trump drew widespread condemnation across the 27-nation bloc by threatening to take control of Greenland, a semiautonomous territory of Denmark. He has backed away from the threat, at least for now.

“If this would happen again, then immediately the tariffs would be installed,” he said at a press conference after lawmakers voted. He said the the protective modifications were “weatherproofing” the Turnberry deal.

The deal will now be further negotiated by EU trade representatives Maroš Šefčovič and his U.S. counterpart Jamieson Greer, who are meeting Friday on the sidelines of the World Trade Organization meeting Yaoundé, Cameroon.

“We need the EU-US deal in force on both sides — delivering real certainty for EU businesses and showing that genuine partnership gets results,” Šefčovič said after the vote in Brussels.

There were formally two votes to introduce clauses to the deal. One passed 417-154 and the other 437-144 with dozens of abstentions each.

The U.S. Ambassador to the EU Andrew Pudzer said the vote would provide “stability and predictability” for U.S. and EU businesses and drive economic growth. “We encourage all parties to think to the future and the importance of unleashing opportunities for businesses on both sides of the Atlantic,” he said.

Malte Lohan, CEO, American Chamber of Commerce to the European Union, said the vote is “the right signal for businesses that have been stuck in limbo over the past year” and “a necessary step towards a more predictable transatlantic marketplace.”

Croatian lawmaker Željana Zovko said the despite the trade spat between Brussels and Washington, trade across the Atlantic had grown over the past year. “This resilience proves the trans-Atlantic trade works, and if it works, we should strengthen it, not hold it back.”
