Fast-fashion giants Shein and Temu are facing increased pressure in the US after two senior politicians pushed for investigations, including into claims of forced labour and intellectual property theft.
In Texas, the state's Attorney General Ken Paxton launched a probe into Shein, mirroring similar moves targeting the firm in several European countries.
At a national level, Senator Tom Cotton called for a federal investigation into Shein and Temu, which he labelled "Communist Chinese" platforms and accused them of intellectual property theft that has "devastated" US firms.
Shein said it took concerns raised about its business practices seriously. The BBC has also contacted Temu for comment.
"We welcome constructive engagement with Attorney General Paxton," Shein said in a statement, adding that it will cooperate with the investigation. The company did not refer directly to Cotton's calls for a national probe.
