Apple fined $570 million and Meta $228 million for breaching European Union law

BRUSSELS, April 23 (Reuters) - Apple AAPL.O was fined 500 million euros ($570 million) on Wednesday and Meta META.O 200 million euros, as European Union antitrust regulators handed out the first sanctions under landmark legislation aimed at curbing the power of Big Tech.

The EU fines could stoke tensions with U.S President Donald Trump who has threatened to levy tariffs against countries that penalize U.S. companies.

The sanctions following a year-long investigation by the European Commission, the EU executive, into whether the companies comply with the Digital Markets Act that seeks to allow smaller rivals into markets dominated by big tech.

Reuters had flagged the EU decisions on Apple and Meta last month.
