Voldemort's effect on world-wide wizardry

Big picture question.  We know that Voldemort is the greatest threat 
to the wizards and witches of Europe for quite awhile, but what 
effect does he have on the rest of the magical world?  I mean, do 
the magical communities of South and North America, Asia, Africa, 
etc....fear or even know about him?  Is he a global threat, or is he 
more localized (with long-range designs on ruling the world perhaps).
Does he have cults of Death Eaters all over the world, who follow 
him from afar?  Or are there similar, but unconnected dramas taking 
place in other places. A Chinese Dumbledore, fighting against the 
evil wizard Cao Cao, with the only safe haven being the Fujian 
Honorable Academy of Wizards!  Ok, letting it get away from 
me....cool to think about though.
