To group all races of Asians as one is to overgeneralize. Asian races are more diverse than the Caucasians, i.e. Indians differ from the Chinese in most respects.
Also, to group all Westerners is a generalization, but I think most of these apply to the majority.
What is interesting is to apply each of these to yourself (westerners) and to our hosts, the Thais and see if it seems correct and then analyze each to determine which way is really better... it will make you think in some instances and you may surprise yourself with some of your conclusions.

Asians: Talk around the circle, especially if opinions are different
