China flags security concerns with iPhones amid reports of ban

China's foreign ministry has denied reports of a ban on international brand handsets, including Apple's iPhones, but acknowledged "security incidents related to Apple's phones," reported both Bloomberg and Reuters. As per reports, China has widened existing restrictions on government employees using iPhones, directing some central agency staff to stop using Apple mobile devices at work. This comes amidst rising tensions between Beijing and Washington, making 'foreign' mobile phones a major national security issue for both countries.
