European trade commissioner Maros Sefcovic will meet U.S. Trade Representative Jamieson Greer in Paris, France, on May 5, following U.S. President Donald Trump's May 1 threat to raise tariffs on EU car and truck imports to 25% from 15%, citing alleged noncompliance with the U.S.-EU trade agreement reached in July 2025, Politico reported on May 4, citing a European Commission spokesperson. No executive action has yet been issued to formalize Trump's threat.

Tensions have risen as EU institutions remained engaged in negotiations to finalize legislation implementing the July 2025 trade agreement, with the European Parliament approving the framework only with conditions, including safeguard mechanisms such as a "sunrise" clause linking tariff removal to reductions in U.S. steel derivative tariffs and a "sunset" clause setting expiry for March 31, 2028. Calls for revisions have also been linked to earlier tensions with the Trump administration, including threats related to Greenland, while a U.S. Supreme Court ruling that struck down part of the Trump-era tariffs has altered the comparative trade conditions underpinning the original deal. Divisions among member states persist, with France opposing rapid implementation while Germany and others support moving forward, delaying finalization of the deal.
