It is not a law of nature that Chinese products are lower quality (cf. electric cars) and I don't see why they would go for that. They can just bin what they produce like everyone else and sell their products for what they have been tested to deliver.

But it is a near law that the first to market attempts will fully embraces the deeply engrained culture of 差不多, until market forces beat it out of the product line.

This has nothing to do about nationality, it has everything to do with building and running a brand new, highly technical, mass production facility.
