China's media watchdog says that stars who have used drugs or visited prostitutes will be banned from state television and other media outlets.

The ban is meant to keep the industry healthy, reported China Daily.

The State Administration of Press, Publication, Radio, Film and Television said recent cases had set a bad example for the country's youth.

A series of celebrities including Jackie Chan's son have been arrested on drug charges this year.

The Chinese government said celebrities who break the law should not be invited to appear in programmes, and transmission of their works should be suspended.

The ban also covers online media, film and publishing.

Jaycee Chan, along with Taiwanese actor Kai Ko, were detained in August after police found they tested positive for marijuana. More than 100 grams of the drug were found in Mr Chan's home.

Another actor, Gao Hu, was detained the same month for possession of marijuana and methamphetamines.

Film director Wan Quan'an and actor Huang Haibo were also arrested on suspicion of hiring prostitutes.

Following the statement's release, productions which starred Huang, Gao and others were dropped from broadcast, reported state news agency Xinhua.
