US Commerce Secretary Howard Lutnick demanded European Union modifications to digital regulations, including the Digital Markets Act & GDPR provisions, in exchange for reducing 50% steel & aluminum tariffs affecting over 400 products during November 24, 2025 Brussels meetings.

The dispute threatens the July Turnberry trade framework establishing 15% baseline tariffs.
