I wonder why the headline says 'Asian' instead of saying Chinese, since all three researchers were Chinese with ties to China. As an ethic Indian, I'm kinda offended when all Asians are just lumped together as I believe it promotes general racism and bias against anyone from that continent .
Cancer center officials have not named any of the five researchers. MD Anderson President Peter Pisters says all are “Asian”; Science has confirmed that three are ethnically Chinese.
Also, race, geographic origin and ethnicity are complicated. "Asian" is as vague in describing the people from Asia as "white" or "European" or "caucasian" are vague in describing those from Europe & Western Asia.
You'd be better with Germanics, Baltic, Persian/Iranian, Kurds, Turks, Slavs (and the multiple breakdowns), Uralic, Latin/Roman, Hispanic (nothing to do with the US 'latino/hispanic'), European Jews (and the different breakdowns) and so on.
Which also brings into play the fact that in Europe the concept of a Nation-State (essentially, a country which is dominated by a people) has been slowly disappearing over the past few centuries (but not entirely), while in Asia IMHO it still seems to be the rule.
