Is this a rhetorical question?
Let's assume for the purposes of this discussion that Chinese workers are every bit as capable of producing a quality product than any other workers on the planet.
^ This statement pretty much sums up what you will hear in comments from people who have actually been involved in business transactions/manufacturing/trade with Chinese factories.
They will, left to their own devices, figure out any and every way to compromise quality to increase their profit margin, even if only by infinitesimal percentages.
Moreover, some of those compromises result in goods that are not only inferior, but dangerous: CFL light bulbs that burst into flames, blade-type automotive fuses (rated at 10 amps) that don't blow until they're loaded with 70+ amps, ad infinitum.
The bottom line being that overall, they cannot be trusted to produce a safe and reliable quality product.
But, we all have the ability to make our own choices about what sort of products we choose to purchase.
YMMV.
If you contract to have something made in China, they will build it to your specifications as long as you keep a representative there to watch the processes.
As much as we Americans like to pat ourselves on the back, for automatically producing a "job well done", reality shows that we have a historical
massive quality control industry in place, that had to be put in place to ensure that everything agreed to is done and that corners have not been cut.
Every factory I ever worked in, had an inbound quality control, batch testing and verifying, raw materials, parts and components, to ensure quality. They had finished product inspection for the very same reason. Every load of concrete I delivered to a bridge, was tested for fudging of raw materials, or too much water, very common in that industry, where a little cheating, pays off over time.

Apple gets flawless products from China, because they demand it and ensure it. Now doubt that quality comes at a price.
Walmart wants Chinese made products cheap. If a broom head fall off, at first use, oh well. It only cost the consumer a couple of bucks and WM 50 cents.
Every American company that imports foreign products, regardless of COO, is 100% responsible for the quality of that product, IMO.
