You're referring to part of the process, I'm referring to the whole process -- i.e. full independent capability / self-sufficiency -- and currently China has zero capability to manufacture advanced chips independently [0] ...
Huawei would love to source its chips and other components
purely from Chinese suppliers, but as of today it is unable
to do so ... There is no production line in China that uses
only equipment made in China, so it is very difficult to make
any chipsets without U.S. equipment.
