Setting aside pollution with melamine, which is clearly immoral and dangerous, there are other problems nobody talks about with respect to doing business with China.

China has a number of different 'dialects.' Wikipedia shows lists of 7 to 14. These dislects are mutually incomprehensible. (Other countries would call them different languages.) Clearly this makes for language barriers.

Chinese writing is based on pictures. A basic education calls for learning 2000 pictograms. (I'm pretty sure I recall that correctly, not that the exact number is crucial.)

Western languages use about 26 letters. We can alphatize documents, store and retrieve them.

But how do you store and retrieve info, guidelines and advice in a writing system that has at least 2000 elements?

My husband once had a corporation from Taiwan as a client. Their method of dealing with environmental reports was to open the door to a small, crowded room, throw in the new document and quickly slam the door.

Obviously there is a lot of scope for chicanery, crime, forgetting, confusion and honest mistakes in a system like that.
