The top antitrust regulator in the European Union said Wednesday she is investigating Amazon's relationship with independent merchants it hosts on its platform.

Why it matters: If this were to turn into a formal investigation, it would represent a major headache for Amazon, as it faces allegations that it has unfair dominance over the market.

What they're saying: EU competition Commissioner Margarethe Vestager pointed to the possibility that Amazon could use data on independent merchants who use its platform to refine its own offerings as a seller itself. She said that "the question here is about the data."

  • Vestager said it was "very early days" and that the authorities have not "formally opened the case."
  • Amazon declined to comment on the record.

The big picture: Debates over Amazon's dominance have fueled a resurgent antitrust movement in the United States, but European regulators have actually taken action against the tech giants.

Taiwan on Thursday marked no locally transmitted coronavirus cases for 200 days, as the island of 23 million people's total number of infections reported stands at 550 and the COVID-19 death toll at seven.

Why it matters: Nowhere else in the world has reached such a milestone. While COVID-19 cases surge across the U.S. and Europe, Taiwan's last locally transmitted case was on April 12. Experts credit tightly regulated travel, early border closure, "rigorous contact tracing, technology-enforced quarantine and universal mask wearing," along with the island state's previous experience with the SARS virus, per Bloomberg.
