any idea which nation produces this line of girls ??

a race of girls exists as this gallery shows that all look very similar and i would like to know their nation of origin ,they are clearly not of japanese or chinese origin all having similar caucasian faces but brownish skin they dot appear to be middle eastern in features i did wonder about latino but if you look at typical latino girls these just dont seem to fit in--somehow south american doesnt seem likely  maybe some south sea islands i am not familiar with may be the answer but does anyone know who they are??
