China imposes sanctions on Boeing and two U.S. defense contractors for arms sales to Taiwan

China's Ministry of Commerce put sanctions on Boeing and two other defense companies for selling weapons to Taiwan. This happened on the day Taiwan's new president took office. China has done this before to other defense companies that sold weapons to Taiwan, which China sees as its own territory. The companies affected are Boeing’s Defense, Space & Security unit, General Atomics Aeronautical Systems, and General Dynamics Land Systems. They are now on a list called “unreliable entities,” which means they can't invest in China anymore, and their top managers can't travel there. Taiwan's new president, Lai Ching-te, wants to make Taiwan safer by buying advanced fighters and other technology. China also froze the assets of General Atomics Aeronautical Systems and General Dynamics Land Systems in China. General Dynamics runs several aviation services in China and helps make the Abrams tank, which Taiwan is buying to defend against a possible attack from China. General Atomics makes drones for the U.S. military, but it's not clear if they sell weapons to Taiwan. In response to Boeing winning a contract to sell missiles to Taiwan, China put sanctions on Ted Colbert, Boeing's Defense, Space, and Security CEO. Taiwan has been dealing with more military pressure from China, with Chinese fighter jets and warships coming close to the island. It's not clear how these sanctions will affect Boeing and the other companies. The U.S. mostly doesn't allow selling weapons technology to China, but some military companies also work in civilian industries like aerospace.
