 EU lawmakers voted on Wednesday to beef up draft rules to rein in US tech giants, including extending the scope to their retailing activities and to their business users outside Europe, as part of their common position in forthcoming talks with EU countries.

The Digital Markets Act (DMA), unveiled by EU antitrust chief Margrethe Vestager in December 2020, sets out a list of dos and don'ts for US tech giants designated as online gatekeepers with fines up to 10 percent of global turnover for violations, a global first.

Vestager's proposal targets Amazon, Apple, Alphabet unit Google and Facebook but the European Parliament wants to extend it to travel website booking.com and online retailer Zalando.

EU lawmakers also want the rules to apply to web browsers, virtual assistants and connected TV, adding to Vestager's list of online intermediation services, social networks, search engines, operating systems, online advertising services, cloud computing and video-sharing services.

The lawmakers' proposal would also make it easier for users to switch default settings on their services and products to rivals.

They want the commission to do an annual report on gatekeepers, with the possibility for lawmakers to propose investigations into new services and new products.

Vestager cheered the vote.

"It sends a clear message that in our EU democracy it is not for BigTech to set the rules of the game, it is for legislators," she said in a tweet.

Lawmakers will now have to reconcile their proposal with that of EU countries and the commission in 2022 before the draft rules can become law.
