That's very dependant on where in Asia. I can tell you that in Israel, which is in Asia, has no true standards, and therefore it is appropriate. Perhaps it is different in other areas of Asia.
Also, "appropriate" in this context refers to what is acceptable as normal. If topless scenes are shown without censorship on a consistent basis in a given region, this makes it "appropriate" even if in absolute standards it's atrocious.
Finally, flg8rmatt's statement does not contradict yours. He simply states that the USA is "one of the few" places; Asia (at least parts of it) can be another "one of the few."
