China continues to clamp down on U.S. tech firms claiming they're spying for the federal government.

Ten Apple products are supposedly banned in China, including the iPad Mini, iPad Air, MacBook Pro and MacBook Air. Surprisingly, Apple can still sell these devices to Chinese consumers.

Several U.S.-based companies are also being closely watched by the Chinese government. These firms include Dell, Microsoft, Symantec and many more.

China claims this has a lot to do with market security and monopoly. The Chinese government, however, quickly refuted these claims and said it's not banning Apple products from the country's procurement list.

Apple reportedly failed to submit the necessary documents to prove that MacBooks and iPads meet the country's benchmarks for energy efficiency.

Apple said it didn't apply to be on China's procurement list and declined to talk further about the matter.

China is said to have banned Microsoft's Windows 8 from all government laptops, tablet PCs and desktops citing security concerns related to Windows XP's shutdown.

Security companies Kaspersky and Symantec have also been banned from the country's approved vendor list. They were replaced by five antivirus software packages made in China.

Banned or not, Apple still leads the global PC market by 14 percent in the second quarter. Research firm Canalys said worldwide shipments of Apple tablets fell by five percent or 48.8 million units in the second quarter of 2014.

It said Samsung and Apple allowed traditional computer makers Dell and Lenovo to step up. Experts believe the PC market will recover stability since tablets were first introduced nearly four years ago.
