US Trade Representative Jamieson Greer has made it unambiguously clear that the United States will not permit the European Union to dictate how American technology companies are regulated, calling the EU’s approach discriminatory and vowing to keep oversight firmly on American soil.

“We’re not going to allow that regulation to be outsourced,” Greer said at an Atlantic Council event in December 2025.

The DMA problem

At the center of this transatlantic friction is the EU’s Digital Markets Act, a sweeping piece of legislation designed to rein in the dominance of large tech platforms. The DMA has been used to target American giants like Google, Meta, and Amazon, companies the EU considers “gatekeepers” of the digital economy.

Greer’s office views this differently. From Washington’s perspective, the DMA disproportionately targets US firms while leaving European competitors relatively untouched.
