SkHynix has manufacturing plants in both Korea and China, so it's a pot luck guess as to exactly where any particular kit is actually made. Swapping ram to the exact same thing, same brand, same speeds just to have Korean manufactured ram vs Chinese manufactured ram is a fools errand, there's no bonus, no 'better quality' like there exists with monitor/tv screens with different 'upgraded' models of the same basic series.
If this is being thought of as some sort of boycott, don't bother, just about everything else in the pc was manufactured in China anyway.
