China has taken action against the US by imposing sanctions on American military-related companies. This move is in response to a recent US decision that restricts certain Chinese tech companies from participating in defense contracts. The sanctions, announced by China's Commerce Ministry, target 10 US companies and block Chinese companies from exporting specific items to them.

These items are described as "dual-use", but further details are not provided here. For more information on this development, readers can refer to the source, which may have additional details on the sanctions and the companies involved.
