I wouldn't say that Chinese culture is necessarily corrupt. Their leaders are, but not the average guy on the street. Arabs, OTOH, have told me deceit is a part of their culture. Hard to argue the point when they tell you this, then you witness it for yourself in their country.....
While I haven't had a problem with any individual Chinese, I have seen multiple companies involved in business dealings with China find out that after sharing their technology they were getting nothing out of the deal. And obviously when you buy any food, drug, cosmetic, chemical, etc. from China, you can't be sure what you are getting without rigorous testing.
So it's caveat emptor pretty much everywhere. I don't doubt that deceit is part of Arab culture. But I'm not sure one can say that this is a unique feature.
