The West would probably cut economic ties with China like they cut them with Russia. For the simple reason that economic ties would help their enemy.
Invadin Taiwan would have a huge negative impact in China. Another poster in this thread, in the process of contradicting himself, said that the longer PRC waits the stronger they become. The conclusion then being that the best course of action for China is to never invade Taiwan. I fully subscribe to this conclusion.
lol it's not contradictory, there are specific PRC strategic milestones that shifts TW scenario, or a broader push to boot US+co out of east asia and gain PRC asian hegemony from potential gamble to forgone. And that's what PRC ultimately wants, their own Monroe. There's a few components left that more or less secures this in next 10/20 years where balance of forces makes US posture existentially unfavorable. The intersection period is mid 2030s-2040s where basically broader strategic balance is baked in, it's just matter of watching relevant trend lines cross (or gap extend). Realistically that's when we can expect things to pop off. The best course of action is for PRC to NOT JUST INVADE TW, but use TW as cassus belli for broader east asian war with US+co to dismantal postwar hemisphereic US security archictecture. The conclusion is, TW is basically PRC's legitmate excuse to shoot US hardware for meddling in domestic Chinese civil war card, it's simply too good to squander right now. Now ultimately international law doesn't matter in WW3, but it helps to have legimate reason to start a constrained WW3 in a way that would cause third parties to sit out (why meddle in ongoing Chinese civil war) and ask why not be net winners while US and PRC and most of east asia "lose". Ultimately for PRC it shouldn't be enough for them to gain TW, but US must also lose east asia.
