BEIJING -- Chinese authorities on Wednesday publicized eight cases showing their success in cracking down on online pornography.

The National Office Against Pornographic and Illegal Publications in 2017 launched a new round of a nationwide campaign against the production, sale and distribution of illegal publications and online pornography that could affect juveniles.

The campaign has specially targeted online streaming and the use of instant messaging and cloud storage services to spread pornography, and many criminal suspects were caught and punished.

In one case, Beijing police in January found a company used its app platform to perform obscene live shows, gaining a large sum of illegal earnings. The platform was shut down and the company had its license suspended by the police.

In another case in east China's Zhejiang Province, the local police found some people using cloud storage services to distribute erotic videos. Two suspects were later apprehended, along with more than 10,000 illegal videos. They were found to have grossed illegal gains of more than 100,000 yuan ($14,500).
