Buyers of mobile phones or computers in Xinjiang will have to register their personal details with police, Reuters reported, citing state media.
It is the latest tightening of restrictions by the government in the restive region in China’s far west.
The measures are designed to “prevent people spreading harmful information and carrying out illegal activities”, the English-language Shanghai Daily reported, citing government officials.
Xinjiang, which borders Central Asia, Pakistan and Afghanistan, has struggled with violence in recent years between the majority Han Chinese and mostly Muslim Uighurs.
Shanghai Daily cited the regional news portal www.iyaxin.com, but the article could not be found on its website. The measures were also reported on Tian Shan Net, a government-run Xinjiang news portal, but later a message said the article had been deleted.
The regulations apply to new or second-hand devices.
Retailers will be required to upload purchasers’ details to a public security database administered by police and to install surveillance cameras in their stores.
Owners and operators of electronics stores will also be required to place warning signs in prominent locations telling people not to spread audio and video content about violence and terrorism, the report said.
Earlier this month, authorities in Xinjiang announced that people buying fireworks for Chinese New Year would have to register using their ID cards, the China Daily newspaper reported.
