If, as proponents of Western civilisation argue (and which I personally believe, FWIW), Western ideals of freedom are universal and every society will eventually want them, then by definition some Chinese studying in the West ill pick up some Western ideals.

If the West is wrong about our ideals being universal, then our society is no better than others anyway and it doesn't matter (in the long run for the overall good of humanity) if the Chinese conquer us.
