EU antitrust regulators levied a record 4.34-billion-euro ($5.04 billion) fine against Google on Wednesday for illegal restrictions on Android smartphone makers and mobile network operators.
The European Commission ordered Google to end the illegal conduct within 90 days or face additional penalties of up to 5 percent of parent Alphabetโs average daily worldwide turnover.
The fine represents just over two weeks of revenue for Google parent Alphabet Inc. and would scarcely dent its cash reserves of $102.9 billion.
The fine, however, could add to a brewing trade war between Brussels and the Trump administration in Washington.
Vestagerโs boss, Commission President Jean-Claude Juncker, is due to meet U.S. President Donald Trump at the White House next Wednesday in an effort to avert threatened new tariffs on EU cars amid Trumpโs complaints over the U.S. trade deficit.
Vestagerโs announcement on Google is expected to include an order to halt anti-competitive practices in contractual deals with smartphone makers and telecoms providers.
Android runs about 80 percent of the worldโs smartphones according to market research firm Strategy Analytics.
The case is the most important out of a trio of antitrust cases against Google because of Androidโs enormous growth potential.
A third case, which has not yet concluded, involves Googleโs AdSense product. Competition authorities have said Google prevented third parties using its product from displaying search advertisements from Googleโs competitors.
Vestager has also ordered a series of measures against other U.S. companies over tax practices in some EU states, notably demanding two years ago that the Irish government take back up to 13 billion euros from Apple Inc.
Some U.S. officials have complained that the Commission is following a protectionist course, while Vestager, a former Danish minister who is seen as a rising star in EU politics, insists she is merely enforcing laws to protect consumers.
