BEIJING/SHANGHAI (REUTERS) - China's new rules around tech exports mean ByteDance's sale of TikTok's US operations could need Beijing's approval, a Chinese trade expert told state media, a requirement that would complicate the forced and politically charged divestment.
ByteDance has been ordered by US President Donald Trump to divest short video app TikTok - which is challenging the order - in the United States amid security concerns over the personal data it handles.
Microsoft and Oracle are among the suitors for the assets, which also includes TikTok's Canada, New Zealand and Australia operations.
However, China late on Friday (Aug 28) revised a list of technologies that are banned or restricted for export for the first time in 12 years and Professor Cui Fan, an international trade expert at the University of International Business and Economics in Beijing, said the changes would apply to TikTok.
"If ByteDance plans to export related technologies, it should go through the licensing procedures," Prof Cui said in an interview with Xinhua published on Saturday.
China's Ministry of Commerce added 23 items - including technologies such as personal information push services based on data analysis and artificial intelligence interactive interface technology - to the restricted list.
It can take up to 30 days to obtain preliminary approval to export the technology.
TikTok's secret weapon is believed to be its recommendation engine that keeps users glued to their screens.
This engine, or algorithm, powers TikTok's For You page, which recommends the next video to watch based on an analysis of your behaviour.
Prof Cui noted that ByteDance's development overseas had relied on its domestic technology that provided the core algorithm and said the company may need to transfer software codes or usage rights to the new owner of TikTok from China to overseas.
"Therefore, it is recommended that ByteDance seriously studies the adjusted catalogue and carefully considers whether it is necessary to suspend" negotiations on a sale, he added.
ByteDance did not immediately respond to a request for comment on Sunday.
China's foreign ministry has said that it opposes the executive orders Mr Trump has placed on TikTok and that Beijing will defend the legitimate rights and interests of Chinese businesses.
