The National Office Against Pornographic and Illegal Publications on Thursday underscored building a clean online and offline environment for social harmony.
The office announced it will launch more campaigns in 2017 to crack down on piracy and online pornography to ensure the healthy development of children and young people.
Issues in live-streaming video, instant chat services and pop-up ads will be dealt with, said the office.
The office also urged early detection and punishment for illegal academic journals as well as blackmail by fake journalists.
In 2016, Chinese law enforcement confiscated over 16 million illegal publications and banned more than 14,000 websites disseminating harmful information.
