I don't think Chinese would be neseccary, alot of Chinese speak english (I think most schools require it), any that would have the luxury of owning a personal computer definetly would. I have heard that more Chinese read and write English than in Mandarin characters, having been there I dunno if thats true but there was a lot of English signs, more Chinese probably read in the romanincized pin yin text than characters though.
English is enough of the global market share for any company, at its peak the British Empire comprised 66% of the world, you can damn well bet that every current commonwealth and most former commonwealths have a large english speaking population.
