China will eventually be able to compete in the mass semiconductor commercial market for non-essential chips, but are about as far away from today's advanced chip manufacturing as your '99 iMac is from the Oculus Rift.

Their 3.7Ghz x86 CPU on DDR5 is only about 7 years out of date tops only on the clockspeed. Kinda close to a coffee lake.

Not to mention China has been funding and driving RISC-V research and development for years, especially with their open source projects using linux.

They're not doing this blind, even 26nm die manufacturing is common knowledge now.

High end chips just happen to be a very expensive market both in resources and technological scale, which is why it primarily grew as a global consortium of companies relying on each other to produce the final product

China has already perfected the art of replicating a globalized industry at home because they have the resources and internal funding. The complexities and proprietary information involved with current gen chip production won't stop them lol. They don't need to aggressively attack Taiwan in any way to achieve what they need. Maybe some cyber espionage to speed things up, which they have done before with military tech, but nothing more lol.
