Apple shares fall after China reportedly bans iPhone use by government officials

The move suggests that China, which is one of Apple's biggest markets, is unwilling to spare any US company in fight to boost homegrown technology

Apple stocks fell after China reportedly banned officials at central government agencies from using or bringing iPhones and other foreign-branded devices into the office.

In recent weeks, Chinese officials were given the instructions by their superiors in workplace chat groups or meetings, the Wall Street Journal reported, adding that it wasn't clear how widely the orders were being distributed.
