Decisions taken by transnational companies and the ideology they assume before the world, will not only interfere in the national context they are directly acting on but also in the international relationships that are established between countries due to political and economical interests. It seems only logic that, many times, this scenario will present challenges that require countries to join forces and to look for solutions that can promote balance in both national and international spheres. Considering the huge relevance of the acts taken by transnational companies all over the world, this book explores theoretical approaches that can enlight the subject and also presents three case studies that will allow the reader to visualize the practical application of the ideas and concepts discussed here.
