SmartScout, a website that provides analytical services to Amazon sellers released its statistics on the top cities of origin for Amazon's products. While before Amazon sourced its goods mostly from American sellers, today 7 of the top 10 are Chinese. Actually, to be more blunt its really Shenzhen that's the main soprano on the stage, while everyone else is just the background choir.

So I guess Tesla ain't the only American company that's in actuality more of a Chinese when all components are broken down. (Actually one make an argument for Amazon at this point being fully Chinese since while at least most of the R&D happens at Tesla and Apple, Amazon's just a conduit for sellers) Jokes aside, is there any doubt now that decoupling has been an utter failure? What supply chain does China not control nowadays? Phones, EVs, EV batteries, as we see from this chart pretty much a complete hegemony over global e-commerce.
Actually no, Vietnam makes Samsung phones and T-shirts, so the answer still is decoupling has been a success and Chinese are repurposing their empty factories to intern those other pesky 500,000 Uyghurs that keep getting magically added to their population annually despite undergoing a genocide.
