American consumer and industrial electronics companies are increasingly unable to deliver products without the Chinese supply chain. How does that not give significant bargaining power? Also factor in that the Chinese manufacturers also manufacturers for everyone else in the world, so they don't have to sell that capacity to USA. And that the share of production capacity that companies from America use is trending down anyways. Mostly due to Asia, Middle East and South America are still growing a lot. Then Africa is following, delayed by some decades.
Of course owning the end customer is generally better. But moving production is not something to take lightly.
