Fu Manchu was a fictional super-villain created by English thriller writer Sax Rohmer, playing into the "yellow peril" propaganda of the time, so I doubt very seriously if this is a Fu Manchu figurine.
It looks like one of the Chinese folk dieties, possibly Shou, with that big forehead, one of The Three Stars gods. Anyhow, you may care to search along those lines instead. of Fu Manchu, if no one comes along with a precise identification (which I think unlikely, given the figurine's lack of the details that are the usual clues.)
Good luck with it. Quite decorative.
