From what I could decipher from the end of the article, it sounded like China has already migrated away from Intel's architecture and replaced it with a different architecture they could get their hands on more reliably—meaning even if the US were to reverse their decision about this denial list, the damage to Intel is already done. This may have killed the demand for Intel's products in China, even if they were free to sell them.

You're not going to switch back to VW just because the spare parts are available on the market again…you've moved on by that point. As we say where I live: «L'avion c'est en vol!» (“The plane has taken off” ~= That Ship has sailed)
