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 affected American firms.

These items are referred to as "dual-use," indicating they have both military and non-military applications. Further details on this development are available from the source, including the full list of companies impacted by the sanctions and any additional information on the restrictions imposed by China.
