Noyb, the Austria-based European Center for Digital Rights, has filed complaints against six Chinese companies over alleged violations of the EU’s General Data Protection Regulation (GDPR). The accused firms include AliExpress, Shein, Temu, TikTok, WeChat and Xiaomi.

TikTok, Shein, Xiaomi and three other Chinese companies were named in a privacy complaint filed on Thursday by Austrian advocacy group Noyb, which alleged the firms were unlawfully sending European Union user data to China.

Noyb, an Austrian privacy advocacy group, filed a series of complaints against TikTok, Xiaomi, AliExpress, Temu, Shein, and WeChat, alleging violations of European Union data privacy regulations.

The General Data Protection Regulation is a rule covering information privacy in the EU. Under that regulation, data transfers outside of the EU are only allowed if the destination country doesn't undermine data protection. Calling China an "authoritarian surveillance state," NOYB is arguing that data transfers should not be allowed to the country.
