The purpose of a literature review is to communicate to your reader what we know - and don't know - about a topic, based on what has been written about your topic in the scholarly literature. Your literature review should SUMMARIZE and SYNTHESIZE research articles that are relevant to your topic. Despite the name "literature review," you are not giving your opinion on a topic or article, as in a movie review; you are recapping what research has already been done in order to point out what new research (YOUR research!) needs to be carried out, and to help your reader situate your research in the context of academic work that has already been carried out.
For individual countries, google "government documents" + name of country. Many countries have at least some of their documents available in English.
