Food made locally is cheap in China also. I'm not complaining about restaurant prices, even the good ones that serve western food (and WTF, why are hamburgers in Beijing better than anywhere else?).

Hotels definitely are iffy in China, most people get ripped off. I don't bother holidaying in China, if I want the beach, its like Thailand or Philippines, the values are remarkably good off peak. I haven't tried Vietnam yet, I heard it wasn't really a resort place yet.
