Chinese authorities said Thursday they had summoned 11 tech companies – including Tencent, Alibaba and TikTok owner ByteDance – for talks on "deep fakes" and internet security, as regulators try to reel in the country's runaway digital sector.
The Cyberspace Administration of China (CAC) said talks concerned "voice software that has yet to undergo safety assessment procedures" as well as the application of "deep fake" technology.
It also said companies should report to the government plans to add new functions that "have the ability to mobilize society."
China has in recent months taken a tough line on the country's fast-growing tech firms, with 12 companies hit with fines last week for allegedly flouting monopoly rules.
Authorities last year halted a record $34 billion initial public offering by Alibaba fintech subsidiary Ant Group.
They called in its billionaire founder Jack Ma and then opened an investigation into Alibaba business practices deemed anti-competitive.
The latest summoning of big tech also involves companies such as smartphone maker Xiaomi, TikTok rival Kuaishou and music streaming service NetEase Cloud Music, the CAC said.
The aim is to ensure they comply with regulations, carry out safety assessments and take "effective rectification measures" if potential hazards are found.
In 2019, China issued rules banning online video and audio providers from using artificial intelligence (AI) and virtual reality technologies to produce "fake news."
"Fake news" has been generalized to mean anything from a mistake to a parody or a deliberate misinterpretation of facts.
Regulations stress the dangers of "deep fakes," meaning technology that manipulates videos to appear genuine but depicts events or speech that never happened.
The CAC notice comes shortly after China blocked the U.S. invite-only audio app Clubhouse.
The app briefly flickered in the mainland before vanishing but has since sparked a number of copycats.
President Xi Jinping on Monday warned about risks surrounding "platform" companies, a term that could refer to mobile and internet firms, and called for greater oversight of the sector.
