If you're cutting off trade to China, you're also cutting off trade from China to the west (US and allies) which would be a massive shock and have devasting effects.
Their industrial base cannot be reconfigured, at the very least, not without years to possibly a decade, not to mention they would need to completely build up from scratch a lot of industry that they no longer have or are so incredibly small that they can't satisfy their needs.
lol
I don't know why you even bother lol
People think that they will cut off China but the West will be better off because they have "wealth". They somehow think that their $10000 in Apple stocks, in their bank accounts, or in their 401k pensions, will still be able to buy something lmao
Any basic estimation would make the dollar something akin to a (not that dramatic but you get the idea) Zimbabwe dollar the moment trade with China is blocked and further disruptions in trade happen due to war. Too much money chasing too few goods. This will lead to rapid hyperinflation which will suddenly make this dollar-denominated "wealth" to be just hot air( unless you are a millionaire/billionaire of course). If they can't even handle a simple Russia economically, forget about doing anything at all on China.
As for China, It will be damaged, but for people who don't understand economics, it will still have its
production facilities. Couple that with overland supplies by Russia and BRI, it will
automatically make China much less damaged than the West
And btw, no, the West can't replace China within a decade. Minimum of 15 years required if they are ultra fast, but more realistically 20-25 years. You need infrastructure, trained workers, workers with the
right mentality, unparalleled bureaucratic efficiency, need specialised machinery factories to be set up to build and equip facilities (no China to buy machinery from any more, Germany can't supply the whole West by itself), entire industries that have been lost and will need to be rebuilt from the scratch etc.
That's why when I see posts saying "oh well just blockade China, we will suffer but we will stand" I chuckle. It would certainly help if we had a person with actual qualifications (*cough* Gatekeeper *cough*) here to explain what happens when too much money chase too few goods
All in all, I would suggest dropping the detailed economic consequences thing as too many (wrong) hot takes are given. Just say economic damage resulting from a potential war and it should be understandable by everyone.
