China sanctions 10 US companies over Pentagon blacklist

China has announced sanctions against 10 American companies, including two rare earth producers, in response to the Pentagon's blacklist of Chinese firms. The sanctions restrict exports of key materials used in defense manufacturing.

The move escalates trade tensions between the two countries. China's export controls target rare earth elements, which are critical for high-tech and defense industries. The US companies affected include those involved in defense and rare earth production.
