First of all, why can't China restrict American Apple phones from entering the China market? Because the China market has been internationalized, it is necessary to act according to international rules, so China cannot restrict Apple phones from entering China.
At the same time, as an internationally renowned enterprise, Apple has a large share in China.
Moreover, there is another meaning for the United States to restrict Huawei.
So, in the final analysis, China's science and technology is not developed enough. Only China has a world-leading position in scientific research and development. The rules of the world at that time were made by China, and you can do whatever you want. Until then, bear it!
