Teaching in South America

This has been a question I have pondered for the past month now.
Is there a demand for Mandarin Chinese teachers in South
America? I have searched the web and asked everyone possible
and have not yet recieved a reply. I am beginning to wonder if

maybe South America is so USA centralized in trade and
commerce that they see no reason whatsoever to deal with other
countries. If this is the case they they maybe very much like
Taiwan such that they can only see and follow money ahead of
them.
I really cannot believe this at all so there must be schools in Brazil,
Chile, or Argentina that have little advertising but are searching
for qualified Chinese teachers. If anyone has any advice please
drop me a comment.
