Finance Minister Bruno Le Maire told RTL radio he had been made aware that Apple Inc. and Alphabet Inc.'s Google unilaterally imposed prices and contract changes on developers selling software on Google Play and Apple's App Store.
"I will therefore be taking Google and Apple to the Paris commercial court for abusive trade practices," Le Maire said.
"As powerful as they are, Google and Apple should not be able to treat our startups and our developers the way they currently do."
Google spokeswoman Mathilde Mechin said: "We believe our terms comply with French laws and are looking forward to making our case in court." An Apple spokeswoman did not respond to requests for comment.
Le Maire also said he expected the European Union to close tax loopholes that benefit Google, Apple, Facebook and Amazon by the start of 2019. Brussels is currently examining measures to improve the taxation of overseas tech giants' online business in European markets.
