Shein, one of the world's largest fast fashion retailers, was unable to answer questions from MPs about the source of its cotton during a hearing at the Business and Trade Committee. The company's general counsel for Europe Middle East Africa (EMEA) was repeatedly asked if Shein uses cotton supplied from China, particularly the region of Xinjiang where forced labor allegations have been made. Shein's representative said she would have to write to the committee with an answer. The lack of information provided by Shein has raised concerns about the integrity of its supply chains.
