But the goal is not simply to give consumers more options. Politicians want European businesses to tap into the region’s diverse economy so they can better compete with the American technology titans that often command a prime spot in whatever European digital market they enter.

European officials hope the removal of online barriers could add tens of billions of dollars to the region’s annual gross domestic product over the next decade. Forecasts estimate that up to four million new jobs could be created as local companies use the latest tech advances to expand across the region. And all Europeans could gain better access to digital and telecommunications services that are still focused primarily within individual countries.

Some of the European proposals are expected to target American companies. Changes to Europe’s complicated copyright rules could force Google and other news aggregators to pay European publishers to use their online content. The Brussels policy makers are also likely to push for legislation to regulate online messaging services like WhatsApp, which is owned by Facebook, in a fashion similar to competing offerings from the region’s own carriers.

And the officials are also expected to announce new investigations into how American-owned online platforms like Uber, the ride-booking service, and Airbnb, the lodging website, operate in the region. Those inquiries might eventually lead to legislation aimed at helping European companies compete on a level playing field with their much-larger American competitors in the so-called sharing economy. Representatives of Uber and Airbnb declined to comment.

Europe’s current patchwork of digital laws and restrictions “are ridiculous,” said Mr. Klena, 26, who commutes an hour each way from Bratislava to his property management job in Vienna and often resorts to pirated websites to watch Netflix shows like “Daredevil.”
