The nation has intensified efforts to clean up the internet from false news and rumours, closing more than 100,000 online accounts over the past month that misrepresented news anchors and media agencies, the cyberspace regulator said.

The Cyberspace Administration of China (CAC) launched a special campaign to clean up online information, focusing on social media accounts that disseminate "fake news" and impersonate state-controlled media.

The regulator said it had wiped 107,000 accounts of counterfeit news units and news anchors and 835,000 pieces of fake news information since April 6.

The cleanup comes as China and countries across the globe grapple with an onslaught of fake news coverage online, with many implementing laws to punish culprits.

The CAC said its review found accounts that had disguised themselves as authoritative news media by falsifying news studio scenes and imitating professional news presenters, using AI to create anchors to mislead the public.

Fake news identified covered hot topics such as social incidents and international current affairs, according to a statement the CAC posted on Monday on its website.

"[The CAC] will guide online platforms ... to safeguard the legitimate rights and interests of the majority of internet users to obtain authoritative and real news," the regulator said, adding it encouraged users to provide leads on counterfeit news and anchors. (Reuters)
