I still remember “Jap Crap”. I would agree, 20 years ago Chinas ability to manufacture was terrible. I import from China. They produce the best quality glasses in the world for a much cheaper price because they have manipulated the currency.

It would not surprise me. The ability to build quickly has been demonstrated in China. Tesla by now, probably have found the cultural differences mean China would be more efficient than the US with I suspect better quality control.
Why not do worldwide supply from China and Texas can do the US.
