Several Chinese agencies and state-owned companies across the country have asked employees not to bring Apple iPhones and other foreign devices to work, Bloomberg reported, citing people familiar with the matter, Reuters and News.ro reported.

For more than a decade, China has sought to reduce dependence on foreign technology by requiring state-owned firms such as banks to switch to local software and by promoting domestic semiconductor chip production.

According to an article published by Bloomberg, several state-owned companies and government departments in at least eight provinces have trained their employees to start using local brands in the past month or two.

Apple did not immediately respond to Reuters’ request for comment.

In December, small firms and agencies in lower-tier cities in provinces such as Zhejiang, Shandong, Liaoning and Hebei, home to the world’s largest iPhone factory, issued their own verbal directives, Bloomberg writes.

In September, Reuters reported that employees of at least three ministries and government agencies were asked not to use iPhones at work.
