Chinese regulators are stepping up efforts to clean up content on the internet with fresh new rules to put the booming short-video industry under closer oversight.

The China Netcasting Services Association, one of the largest internet associations in the country, released two sets of regulations Wednesday that will be applied to industry players including Beijing ByteDance Technology and Tencent Holdings.

The new rules detail 100 categories of content that would be banned from such services, including violence, sex, superstition and separatism, or advocating separate status for Taiwan, Xinjiang and Tibet.

Content that “ridicules, satirizes, opposes or defames the socialist mode, theory or system and Chinese culture, as well as the country’s major policies,” are not allowed under the rules.

Videos that leak national secrets or damage social stability and national unity will also be banned.

The new rules require short video app operators to set up content review mechanisms to ensure that all content, including titles, introductions and comments, are reviewed before broadcast.
