Nobody CARES about the NAND chain written in Chinese by the Chinese. You make 3DNAND by LICENCE issued by people who ACTUALLY invented 3DNAND,Toshiba of Japan.
No Chinese company has invented ANYTHING SIGNIFICANT not one product that the Chinese can say we invented that, it all comes from Western companies who innovate and invent.
You cannot build a FAB in any other country or even your own without the Western licences for the IP and the Litho machines.
China has NEVER built a fab outside of China and never can unless it receives licence approval from the West.
The announcement by Pakistan is just hot air and a word salad.
Chinese skilled unemployment is skyrocketing. Chinese are desperate to keep their skilled industries. While in theory anything is doable ask yourself if a country that would not lend Pakistan 1$billion when Pakistan was in EXTREME difficulty begging daily for the past year for that billion, daily expecting to default, would invest $20-40 building a Fab in Pakistan.
