A day before China’s new algorithm regulation takes effect, the country’s internet regulator highlighted a new focus on getting firmer control on companies that can influence public opinions and use algorithms in their services.

Providers need to file a self-evaluation report of their algorithms, among other documents. [CAC, in Chinese]
