And historical record of the lack of QA coming from Chinese manufacturing

China is a gigantic country where one in 6 humans live that either produce directly or indirectly, 70%+ of the world's goods.

It's quite difficult to make general statements at such a gargantuan scale encompassing every single sector.

China has an abundance of terrific QA in electronics and advanced technologies as much as it has an abundance of the opposite, just simply due to its sheer size.
