Point of note: "Asian" in the US seems to mean "China, Indochina, Japan". In the UK it typically means "Indian subcontinent" (India, Pakistan, Bangladesh). (And black folks in the UK are not "African-American" -- they're more likely to be Anglo-Jamaican, but can also be, well, African. For values of "Africa is a continent the size of both the Americas, with a population of around a billion people, so you need to be more specific.")

Even where the same labels exist, they may be applied to something completely different. And the meaning attached to such labels may differ significantly (something that's insulting or derogatory in one culture may be descriptive in another).
