I don't know the original intentions, but I don't feel it's anti Chinese just by itself.

It could be pro-Chinese if you frame it like they give merit to anyone involved, or that they take care of their most valuable employees (maybe they pay them another way), or whatever.

Or just observant of how Chinese labs publish their stuff. (Not sure if it's always like that I haven't take a look at the number of authors in this type of publications. Or at least I can't remember it.)
