The European Commission has accepted a set of binding commitments from Alibaba’s AliExpress in response to concerns over the dissemination of illegal and pornographic materials on its platform, the EU’s executive arm announced on Wednesday.

The decision follows an investigation launched in March, which focused on AliExpress’s failure to adequately prevent and remove prohibited content, including unregulated medicines, food supplements, and adult material. The inquiry raised the possibility of a significant fine under the EU’s Digital Services Act.

In a statement, the commission said it had endorsed a series of “wide-ranging commitments” by the Chinese e-commerce giant, making them legally binding. These include strengthened systems for monitoring and detecting illegal products, greater transparency in advertising and algorithmic recommendations, and enhanced traceability of third-party sellers on the platform.

However, regulators warned that AliExpress could still face penalties. The Commission’s preliminary findings suggest that the company underestimated the risks posed by illegal content and failed to adequately sanction repeat offenders among its traders. AliExpress retains the right to respond to these findings.

“We have proactively engaged and closely collaborated with the European Commission throughout this process from the outset, and we will continue to do so,” AliExpress said in a statement. “We are confident that a positive and compliant result will be achieved through continuing our mutual dialogue with the Commission to address any remaining concerns.”

The case marks one of the first major enforcement actions under the Digital Services Act, which requires large online platforms to take stronger steps against the spread of harmful and illegal content in the EU digital market.
