It seems you skipped this part in the paper you cited:
Extensive research identified a CQ transporter, P. falciparum CQ resistance transporter (PfCRT), which functions in resistant but not wild-type strains of the parasite (2, 8⇓⇓⇓⇓⇓–14).
So who is incorrect now? Next time don’t be in hurry to cite papers you haven’t read.
