Fifteen million illegal publications were confiscated and 28,000 websites deemed pornographic or featuring other illegal content were shut down in China in 2015.
The figures were announced by the National Office Against Pornographic and Illegal Publications on Friday, reviewing its achievements.
The campaign against online pornography and illegal publications will continue through 2016.
Authorities will focus inspections in areas around schools to uncover shops selling publications such as obscene comics, the office said.
Moreover, practices such as sharing links to pornographic websites or cloud storage, set top box and online game websites with obscene content will also be targeted and those implicated punished, according to the office.
