US President Donald Trump has threatened the European Union with significant new tariffs in response to Brussels fining major American technology firms, accusing the EU of taking "direct aim" at US companies. The threat follows a €890 million ($1bn) fine levied against Google earlier this week for breaching EU competition rules under the Digital Markets Act (legislation designed to regulate large digital platforms and curb anti-competitive behaviour), with Apple and Meta having faced similar penalties last year. The move comes just one day after the Trump administration imposed a sweeping 10% tariff on EU goods as part of a broader round of global trade measures, raising fears of a deepening transatlantic trade dispute.
