Speaking to CNBC, Europe's competition commissioner, Margrethe Vestager, insisted that allegations of discrimination by the antitrust agency were unfounded.
"I hear that as well, and I take that extremely serious(ly), because if that was true, it would be highly critical. So of course we look at the stats and we cannot find the bias," Vestager explained.
Critics have accused Vestager of undue scrutiny of U.S. multinationals since she took office in 2014, after which the European Commission started raising regulatory questions around American tech giants like Google and Amazon.
Google could be facing fines equal to about 10 percent of its global turnover after the competition watchdog accused the company of "abusing its dominant position" in the web search market, saying it favored its own shopping comparison services in general search results.
