European Commission President Ursula von der Leyen rebuffed U.S. President Donald Trump's threat to raise tariffs on European automobiles on Tuesday [1].

The dispute threatens to destabilize a fragile trade truce between the two economic powers and could ignite a broader trade war affecting the global automotive industry.

Speaking in Brussels, von der Leyen responded to plans by the U.S. administration to increase tariffs on European cars to 25% [1]. This would be a significant increase from the 15% level established under the existing EU-U.S. trade deal [2].

"A deal is a deal," von der Leyen said [1].

The European Commission President said that the EU will stick to the current agreement and warned that Washington must honour its commitments under the deal reached last year [3]. She said that the European Union is prepared for all scenarios regarding the trade dispute [2].

The tension arises from the U.S. government's desire to renegotiate terms or impose higher costs on European imports to protect domestic interests. However, von der Leyen said that the existing framework remains the authoritative guide for bilateral trade in the automotive sector.

Brussels has historically sought to avoid aggressive retaliatory measures, but the current rhetoric suggests a hardening of the EU's stance. The commission's insistence on the validity of the previous agreement serves as a diplomatic shield against unilateral changes to tariff structures.

“"A deal is a deal."”

This confrontation signals a breakdown in trust between the U.S. and EU regarding trade stability. By publicly insisting that 'a deal is a deal,' von der Leyen is attempting to lock the U.S. into previously agreed-upon constraints to prevent a volatile shift in market pricing for European car manufacturers.
