Basically:
China floods the market with cheaper but less QA'd parts, makes a gazillion dollars, is able to spend said money to fix yields / QA issues and streamline operations, by the time that happens Micron and maybe a few other existing players will have new memory production, and then we'll have a flood of cheap, reliable memory. 4yr, maybe?
Seems it's mostly useful for LPDDR modules which are predominantly used in battery-powered devices and to improve margins.

The US did it when it was a bigger steel supplier, good steel was sold domestically, crappy steel was sold elsewhere. If you got crappy steel in Africa at the time you might have thought US steel was garbage with poor QA, but in reality US steel was great and they just shipped the crappy stuff because people still kept buying it.
My endlessly excellent Chinese gear (Dahua cameras, XikeStor switches, etc) doesn't know what you're referring to.
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.
I remember reading about it in Linux contexts decades ago, and these days it's something that Windows does automatically.
When can I expect this flood of cheaper RAM with less QA? I'd like to contribute to the gazillion dollar pile as soon as possible.
