While Edward Snowden seeks to renew his asylum in Russia, the government of China – which Snowden’s leaks revealed was spied on by the National Security Agency – is casting a shadow on U.S. tech firms doing business in China. The latest target is Apple Inc. and its popular iPhone, which China Central Television is claiming has a feature that may breach China’s national security, according to the Wall Street Journal.

Apple’s iOS7, the operating system on iPhones around the globe, remembers time and location of users’ location, such as when they post on Facebook or check into a restaurant or a museum using a third-party app. This, CCT reported during a noon-time broadcast to millions of Chinese households, can potentially be used against individuals working for the Chinese government.

The iPhone has been available in China but Apple’s second quarter sales in China increased 13 percent year-over-year since the Cupertino, Calif.-based company signed a deal making the iPhone available to 750 million customers of China Mobile, the world’s largest mobile carrier, according to Forbes.

Subsidized iPhones were previously available only for customers of China Unicom and China Telecom. Apple competes against China’s smartphone manufacturers, including Xiaomi, which is looking to internationalize to foreign markets, according to the South China Morning Post. 

CCT’s report cited unidentified – and presumably, Chinese – researchers who revealed that Apple and, by extension, the U.S. government, could gain “access to those data points” and “gain knowledge of the broader situation in China or even ‘state secrets,” according to an abstract of the WSJ article, posted on Marketwatch.

Since Snowden’s disclosures last year that the National Security Agency was spying on Chinese officials, companies such as Apple and Google have been under higher scrutiny in China and there’s sentiment among the Chinese officials that private U.S. tech firms are in cahoots with the NSA.
