Facebook parent Meta says Chinese law enforcement is behind the largest covert online influence operation the company has ever disrupted.

The operation spread pro-China messages and attacked critics of Beijing's policies, using a sprawling network of fake accounts across more than 50 websites, from Facebook and Instagram to YouTube, Twitter (now known as X), TikTok, Reddit, and dozens of smaller platforms and forums.
