China is restricting the use of Tesla’s electric cars by military personnel and inside of military complexes citing security concerns, according to an article in the Wall Street Journal. Specifically, the Chinese government is worried about sensitive data being collected by cameras built into the vehicles.

In a review of the vehicles, Chinese officials were concerned that the sensors in Tesla automobiles can record the data of their surroundings. Tesla can download when and where an automobile is being used; it can even download a user’s contact list off his cellphone. 

The Chinese military has reportedly issued an order telling military members to park their vehicles off base property. Chinese Communist Party officials are worried that this personal information can be then transferred back to the United States.

Late last month several human rights organizations accused Chinese biotech companies of using human DNA for security purposes, such as tracking would-be criminals and Muslim Uighur people. Most biotech companies use DNA to develop medicines.
