SK Hynix and Samsung are South Korean.
The Korean memory makers are playing the same game as Micron and simply moving existing capacity up-market.
GP was referring to upstart Chinese memory manufacturers like ChangXin, who - if their yields manage to catch the wave - could not have asked for a more favorable market after the big 3 have abandoned the consumer segment. Consumers who would have otherwise turned up their noses at CXMT will not have the luxury.

However with corsair giving it their blessing, and their technology having matured a bit (a lot?), and more reviews showing good stability (longevity I suppose, is TBD) they're definitely worth recommending these days.
