None of that makes any sense. "Western chips" all come from Taiwan in the first place. "Western designed chips" are also in laptops and mobile phones, including tons of Chinese devices, and that's assuming you mean to include South Korea as "Western", which is a bit of a stretch. Those are fundamentally interchangeable with military hardware. Nobody is putting 4090s and A100s in ICBMs.
Make it make sense. What specific hardware is this stopping from getting to China and for what application?
