China has taken action against the US by imposing sanctions on 10 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, will block Chinese companies from exporting specific items to the targeted American firms.

These items are described as "dual-use", implying they have both military and non-military applications. Further details on this development are available from the source, including the full list of affected companies and the specific items subject to export restrictions.
