Tesla's China-made vehicles meeting the nation's data security criteria led to local Chinese authorities lifting limitations on Tesla cars, as announced by the automaker on Sunday.

This breakthrough occurred during Beijing's first significant auto show in four years, coinciding with Tesla CEO Elon Musk's unscheduled meeting with Chinese Premier Li Qiang.

Despite Tesla's popularity in China, concerns about data security previously restricted the company's electric cars from some government-affiliated facilities.

Tesla's Model 3 and Model Y, along with new energy cars from other manufacturers, have also cleared China's data security regulations.

The lifting of restrictions coincides with Elon Musk's visit to China, raising expectations for the imminent release of Tesla's "Full Self Driving" software in the nation.
