The world's biggest country now has the most people online.

China now has 233 million internet users, surpassing the 220 million in U.S.

Everyday China has 200,000 new internet users.

Critics have blasted China's controversial firewall that monitors internet use, and blocks certain content, like news websites from the U.S.

In one month, police arrested nearly 900 people because of "unhealthy content online."

Advocates say the firewall protects against pornography, viruses and spam.
