This textbook is the result of academic research to hold a teaching of the same title. It discusses the issues of international relations and the configuration of the world order. If we understand the theme and content, more than half of the countries in the world are still New States in International Relations. Their weight in the international stakes is important, not only because of their potentialities in raw materials, but also because of their rate of economic emergence and their ability to contribute to the search for remedies to the problems of the hour.
