Probably, over a longer period of time, it is cheaper to transport samples(across the globe) and process them automatically, than pay (local) staff for handling samples and process them automatically in the same region.
Also, installing imported machinery in a country might be an issue.
BTW, what is the turn around time for these companies, if the samples are shipped to Korea? The sequencing department (on the same floor)at my uni took 3 days.
Good question about the turn around time. No idea. But ist faster then 3 days I think.
It does seem strange, being cheaper to send it so far.
