The semi tools sector is a good indication of this. The ZTE sanctions were 5 years ago. And Huawei got banned from using TSMC in 2020. So where are the Chinese semi tools and production line? Nowhere. Even 90nm production lines using dry lithography like the one by Nexchip still use imported tools. This is pathetic to be honest.
Still no operational dry lithography production lines, let alone immersion, or even less likely EUV. At this rate they won't deliver immersion lithography before leading edge fabs use second generation high-NA EUV.
Production of advanced materials like photoresist and mask material is still way below required for self-sufficiency, same is true for certain display panel materials. Only bright spot in materials is wafer production which seems to be ramping up quickly, but this is thanks to huge existent investments into solar panel materials sector.
