As an American currently in China, I second this thought.

I have a Chinese wife and she lambasts me when I first brought up the notion of tipping over ten years ago. Part of the problem is, IMO, the Chinese know that it is in American or Western Culture to tip so they have no problem asking for it. Also, they appear to believe all Americans are wealthy beyond belief and a few RMB will not dent the wallet. These days though, there are more Chinese wealthy individuals than Americans and they have no problem not tipping.

Granted there are situations at Very upscale restaurants that you may feel inclined.

This is just my experiences.
