Donald Trump has threatened to hit the European Union with substantial tariffs in response to penalties the bloc has imposed on major US technology companies. The warning adds a trade dimension to an already tense dispute over how Europe regulates large American digital firms.

The latest flashpoint came after Brussels fined Google a total of €890 million. EU authorities said the company had illegally given preferential treatment to its own services over rivals in search results, deepening a long-running clash over competition rules and the power of big tech platforms.

Trump’s comments suggest he sees the EU’s actions not just as antitrust enforcement, but as measures that unfairly target US businesses. By raising the prospect of tariffs, he signaled that Washington could answer European regulatory action with economic pressure of its own.

The dispute highlights the broader friction between the United States and the European Union over technology, market competition and cross-border trade. With Google and other US tech groups facing continued scrutiny in Europe, the risk of the disagreement spilling further into trade policy now appears higher.
