BEIJING, April 26 (Xinhua) -- Four government agencies on Friday jointly launched the "Sword Net 2019" campaign targeting copyright infringement on the internet, especially "paraphrasing plagiarism" by so-called "we media" accounts and illegal and irregular activities by image agencies.

Initiated by the National Intellectual Property Administration, the Cyberspace Administration of China, the Ministry of Industry and Information Technology and the Ministry of Public Security, the operation is set to run from the end of April to the end of October.

Authorities vowed to severely crack down on unauthorized reproduction of media outlets' new products and acts of plagiarizing, distorting and abridging media outlets' news products by "we media," or social media accounts run by individuals to provide information products.

The illegal filming and recording in cinemas, the spread of pirated film and television work via the internet and the unauthorized distribution of products via smart devices and streaming media software will be strictly dealt with, according to officials.
