China is tightening control over artificial intelligence companions, with new rules targeting virtual partners designed to create emotional connections with users.

The regulations ban AI or virtual romantic companions for minors and require platforms to stop chatbots from encouraging emotional dependence on machines.

Millions of Chinese users who formed relationships with AI companions have been affected, with some criticising the move and describing the shutdown as an emotional loss.

Authorities say the crackdown aims to protect social relationships and prevent excessive reliance on digital companions.

The move highlights a growing global debate over how governments should balance AI innovation with concerns about mental health, human connection and online safety.
