On June 28th, local time, the EU antitrust agency announced that it will seek further regulatory scrutiny of Microsoft's collaboration with OpenAI and Google's trade with Samsung in the field of artificial intelligence. These measures by the EU highlight the unease of global regulatory agencies over large technology companies using their dominant position in new technology areas. On the same day, Microsoft and Google's stock prices fell nearly 2% respectively. Yunting You, a partner at Shanghai Dabang Law Firm, analyzed to reporters, "I believe that under the existing antitrust legal framework, it is difficult for the EU to find antitrust compliance issues with Microsoft's investment in OpenAI, even if there are some exclusive clauses, not all exclusive clauses are illegal." However, he also pointed out that in the overall trend of stricter EU regulation of technology giants, if the EU introduces a new regulation similar to the Digital Markets Act (DMA), such as a "digital gatekeeper obligation," it may impose more restrictions on the investments and mergers of large companies.
