US adds Tencent, CATL to list of 'Chinese military companies'

The US Defense Department has added Chinese tech giant Tencent and battery manufacturer CATL to a list of companies it says are affiliated with Beijing's military.

Tencent's shares plummeted more than 7 percent in Hong Kong on Tuesday, while CATL saw its shares in Shenzhen sink 5.2 percent.

The two firms were included on a list of "Chinese military companies" operating in the United States that is due to be published Tuesday on the US Federal Register, with copies available for download the day before.

Tencent is one of the top players in China's expansive technology sector, operating the WeChat "super-app" with other offerings across gaming, content streaming and cloud services.

CATL is also a major firm, producing more than a third of the electric vehicle batteries sold in the world.

They have been used in models from a long line of foreign manufacturers including Mercedes-Benz, BMW, Volkswagen, Toyota, Honda and Hyundai.

A spokesperson for Tencent said the company's inclusion on the list "is clearly a mistake," and that "we are not a military company or supplier."

"Unlike sanctions or export controls, this listing has no impact on our business. We will nonetheless work with the Department of Defense to address any misunderstanding," the spokesperson added.
