I think it's a learning curve, not long ago they were dirt poor, <deleted>ting on the streets (which they still do in foreign countries according to news reports) and in less than a generation, they have the means to vacation abroad, which of-course they do take advantage of.
It would really help if the Chinese government would help their county's reputation, by schooling people traveling abroad, if even for an hour or two, perhaps at the airport, but I guess they have more important things to deal with.
