Google has been fined €890m (£759m) by the EU for allegedly abusing its power by favouring its own apps and services over those from rivals.
It is the first major action against the tech giant under the EU's Digital Markets Act (DMA), a landmark law aimed at curbing the power of the world's biggest tech companies.
The Commission argued Google's practices limited consumer choice and gave its own services an unfair advantage over rivals.
But the firm criticised the decision, arguing the EU's requirements could damage services used by millions of European customers.
"To comply, we are having to strip away real-time Search features Europeans love - like instant pricing and direct availability for hotels, flights and restaurants - and dismantle safety protections on Google Play," said Google's president of global affairs Kent Walker.
"This isn't fair competition."
EU officials rejected that argument, saying the measures are necessary to prevent dominant platforms from disadvantaging rivals.
The total fine handed down to Google is comprised of two separate breaches of the DMA.
The European Commission imposed a €460m penalty after finding Google favoured its own services for helping people book flights and hotels over competitors in search results.
And it gave the firm a further €430m fine due to its Play Store rules, with regulators saying it didn't allow people to be shown cheaper offers available outside Google's own marketplace.
Google has a long history of disputes with European regulators, having previously received billions of euros in fines over separate competition cases.
EU competition chief Teresa Ribera said companies should succeed because of the quality of their products - rather than their market position.
"The best products should succeed because they're better, not because they're owned by the company running the search engine," she said.
EU tech boss Henna Virkkunen echoed those thoughts.
"After this decision, we want to make sure that there is more competition and also other companies are able to innovate," she said.
Zach Meyers, director of research at the Centre on Regulation in Europe, noted a delay in the competition authority finalising its decision against Google, telling the BBC it was likely driven "by a desire not to upset EU-US relations".
As US president Donald Trump has frequently threatened or imposed new tariffs, however, the Commission came to see its efforts as futile and went ahead with the fine.
"It reflects a growing view among EU officials that the US president's unpredictability and unwillingness to comply with his own deals means that the EU has little to gain by treading softly - and potentially a lot to lose in terms of regulatory credibility," Meyers said.
Google now has 60 days to comply with the regulations - or challenge them by taking the Commission to court.
