Apple Watch is banned in China, as the government has ordered a halt to all sales of the device.

Apple’s smartwatch has been banned in China after a watchdog agency claimed it could be used for spying. The Chinese government has ordered a halt to all sales of the Apple Watch Series 4, as well as any other smartwatches from the company. It comes after an official with China’s National Radio Measurement and Test Centre (RMCAT) warned that Apple Watches can be used to “spy on our military operations” and “undermine our national security.”

The ban was reported by Chinese newspaper Global Times, which said that “all wearables” have been outlawed in order to prevent them from being used for spying. The move is part of an ongoing crackdown on foreign technology products by the Chinese government.

“We will not allow any companies or individuals to sell products that are unsafe,” said Yang Xiaodong, director of RMCAT. “If they are found selling such products, we will punish them according to related laws and regulations.”
