Google's regulatory fights with Europe raged Monday as the tech giant was accused once again of unfair business practices, this time by a Russian anti-monopoly agency. The Mountain View, California, company abused its position of dominance with its Android mobile operating system, the agency said. 

Google violated Russian federal law by preinstalling services like Google Search, Google Maps and YouTube on Android devices, Russia's Federal Antimonopoly Service said Monday. FAS said it will issue its full ruling on the matter in 10 days.

"We haven't yet received the ruling," a Google spokeswoman said, according to the Wall Street Journal. "When we do, we will study it and determine our next steps."

For the tech company, Russia's ruling is the latest in a series of skirmishes with European regulators. Earlier this year, the European Commission charged Google with violating its position of dominance in the search market. Google has refuted the claim but faces the possibility of a multibillion-dollar fine. Separately and similarly to Russia, the European Union also is investigating the tech company to determine if Android violates any antitrust laws. That investigation is not yet finished. 

In Russia, Google now faces the possibility of being fined up to 15 percent of revenue it drew from that market in 2014. The company also may have to change the way it does business with Android or face the possibility of more fines. 

FAS began its investigation of Android in February after receiving a complaint from Yandex, Google's top Russian rival. Though Yandex dominates the Russian search market, Google recently has been making gains in that market and become a bigger threat. 

"We welcome the positive ruling of the Federal Antimonopoly Service," a Yandex spokesman said, according to CNET. "Although the European Commission has already begun a formal investigation in relation to these same practices, Russia is the first jurisdiction to have officially recognized these practices as anti-competitive," the spokesman said.
