First of all change your thoughts, because if you are living in a developing country or third world country then it is not a bad thing, the other thing is that you blog must have contents for all world not only for your country, if your blog has contents for all world and they find your blog through search engine then they will land on your blog and can see the ads of their interest. So first of all make your blog contents interested for whole world and then apply for chitika. If they approve, they will start showing ads on your blog. The other thing to mention here is that, chitika don't have their own ads, advertisers from USA, Canada and europe advertise on chitika for their countries, in simple words, if you have some product in you country Nepal, then you will advertise it for your country not for Pakistan or india, the same happen with USA, Canada and european countries, so stop blaming chitika and start blogging with positive thoughts.
