Besides the hypocrisy noticed by other posters, there is a problem with the so-called sanctions of USA against China: they are not sanctions. True sanctions are associated with some political conditions. For instance one can apply some sanctions against Russia until it stops its war against Ukraine. In the case of the so-called sanctions against China no valid reason is provided for them and there is no "until". Real sanctions against China would be tied to some explicit requests, for example one could request from China to recognize Taiwan as an independent country, or to provide guarantees that they will not attempt to extend their territorial waters, or to guarantee certain rights for minorities, or whatever other changes in their current behaviors that are criticized by USA would be deemed as appropriate. Instead of this, USA has not requested anything from China, and the official motivations for the sanctions are ridiculous. Many Chinese companies have been blacklisted because they provide products or services for the Chinese military forces. This is a normal behavior for any company in any country. Plenty of the most important US companies provide products or services for the US military. If all these US companies would be blacklisted by other countries, it is likely that the participation of USA in the international commerce would disappear almost completely. While some of the less important US sanctions have at least this claimed purpose of weakening the Chinese military, even if no explicit rationale is given for why this is a legitimate goal, the most important US sanctions do not have any other goal than to eliminate the competitors of some US companies. For instance the war against Huawei has begun exactly in the moment when Huawei was on the verge of surpassing Qualcomm in the production of chipsets for smartphones and they were clearly demonstrating a superior capacity of innovation over Qualcomm. The second great wave of sanctions against SMIC and other important semiconductor device manufacturers has begun exactly when the Chinese were close to take a significant market share for flash memories from Micron. In both cases the US sanctions have succeeded to remove from the market for consumer products the Chinese competitors of the US companies, preventing thus a drop in the prices of smartphones and SSDs, which would have been beneficial for everybody in the world except for the shareholders of a few US and Korean companies, but their effect against the Chinese military is likely to have been close to null.
