According to the official account of the "European Union Chinese Chamber of Commerce", the European Commission officially announced on May 15 that TikTok has failed to fulfill the relevant obligations stipulated in the Digital Services Act (DSA) in terms of the setting up and disclosure of information in the advertising library, especially in terms of advertising transparency. "There are major deficiencies." The European Commission emphasized that this determination is intended to formally notify TikTok of its current compliance issues and has not yet constituted a final conclusion. If TikTok is finally confirmed to have violated the regulations, the European Commission may make a formal ruling and impose a fine of up to 6% of its global annual turnover. In response, TikTok responded that it is verifying the findings of the European Commission and remains committed to fulfilling its obligations under the Digital Services Act. The company said in a statement that while supporting regulatory goals and continuing to improve our advertising transparency tools, we disagree with some of the European Commission's interpretations and pointed out that the relevant guidelines are preliminary findings rather than clear public guidelines.
