STOCKHOLM, July 17 (Reuters) - Austrian advocacy group

noyb on Thursday filed data privacy complaints against China's

AliExpress, TikTok and WeChat, saying they failed to comply with

European Union laws on providing users a full copy of their

data.

While most tech companies have a tool that allows them to

fulfil requests for downloading user information, some Chinese

companies have made it difficult to access the information, noyb

said.

"TikTok, AliExpress and WeChat love collecting as much data

about you as possible - but vehemently refuse to give you full

access as required by EU law," said Kleanthi Sardeli, data

protection lawyer at noyb.

Noyb is known for filing complaints against American

companies such as Apple ( AAPL ), Alphabet, and Meta

, leading to several investigations and billions of

dollars in fines.

In January, noyb filed complaints against six Chinese

companies and sought to suspend data transfers to China and

called for fines that can reach up to 4% of a firm's global

revenue.
