If "the Chinese are targeting Asians", why would the most prominent example be a non-Asian? Presumably being a prominent researcher makes one harder to influence, and if they were targeting Asians, it would have to be because being Asian makes them easier to influence. If the goal is to influence the most important research, then you would want to influence the most prominent researchers, of which the lowest cost researchers to influence would be a prominent Asian researcher, not a promiment non-Asian researcher.
In addition, if your goal is finding influence, and you end up finding one non-Asian being prominent lyinfluenced, and a bunch of Asians not being as prominently influenced, it generally either means non-Asians are being more prominently influenced in general, or you've been ignoring non-Asians to the point that you only notice the prominent ones.
