optimize your campaign in targeting those areas. I got visitors from those places but just a few. And use their freakin language if you want to be visible there. You cant possibly rank your English keywords in china because they search only for Chinese language.
Submit links of your services or products in some specific bookmarking, article, blog sites and directories of those specific area or country. Use those country name with your meta title and meta keywords. You will see effect in few time.
I also dont get traffic from those country but I don't mind not getting traffic as they dont produce quality traffic until and unless you are targeting those country for your product
