The China Netcasting Services Association (CNSA) is targeting what they consider "abnormal" sexual activity.
The rules which were issued on Friday demand that online video platforms hire at least three “professional censors”.
They were ordered to view entire programmes and take down any considered not sticking to the “correct political and aesthetic standards,” according to the latest regulations.
The move is seen by human rights groups as the latest tightening of censorship in China.
Other online material deemed offensive include damaging the national image, criticising revolutionary leaders or portraying the supernatural such as “conjuring spirits”.
In 2016, Freedom House, which promotes democracy and human rights, condemned China as the “worst abuser of internet freedom” in the world.
Homosexuality in China was decriminalised in 1997 and remained on the official list of mental illnesses until 2001. »
