Articles like this one can lead to a number of generalizations and stereotypes, not the least of which could divert you into a racist corner that it would be impossible to get out of. If you're any kind of a blogger who hates attention, like me, there are so many ways this post could go wrong.
Chinese tourists really aren't any different from any other group. They do like to go up to young boys or girls with curly blonde hair and touch it--this I have seen with my own eyes. Your various other groups might ask permission to pat a head or take a picture, and that may be the case with some tourists from China.
My guess is that the new "ugly American abroad" will one day be "the Chinese farmer with a passport" and a whole host of cliches will be born.
