More Manifold Destiny

There has been intensive discussion of Nasar and Gruber’s Manifold Destiny at Not Even Wrong, in these threads: Latest on Poincare, 2006 Fields Medal Winners, and Some Links. The controversy centers around whether Nasar and Gruber are unfair to Yau, but has taken an interesting turn: some of the commenters accuse the article of perpetuating stereotypes of Chinese mathematicians. The existence of a stereotype of Chinese mathematicians is news to me (ironically given the situation, there is a well-developed stereotype of Russian mathematicians that I have heard people invoke), so I’m curious if anyone else has ever heard any such stereotyping.
