"The European Union will pay a very high price for this illegal and highly unethical action, which I have consistently warned them about," the US president writes on Truth Social.
The threats come after the EU fined iPhone maker Apple and Facebook owner Meta 500 million and 200 million euros respectively for violating the EU's Digital Markets Act.
On Thursday, it became clear that Google was also found guilty of violating the same regulation.
According to Trump, an investigation is now being launched to see whether the EU is “robbing” US companies in this way. He expects the fines to be lifted and a “significant tariff” to be imposed on the EU.
Swedish EU parliamentarian Karin Karlsbro (L) comments on Trump's remarks.
"Sigh," begins her post on X.
"American companies operating in the EU must follow our rules. The EU must not allow itself to be blackmailed by Trump's new tariff threats. The Turnberry Agreement (what the EU and the US have agreed on current tariffs, editor's note) is crystal clear: if tariffs above 15 percent are introduced, the agreement will no longer apply."
