This book presents cutting-edge research and exploration of the role of nation-state when big tech firms present themselves as new participants in contemporary international relations that act on an equal footing with nation-states. The general research goal of this book is to identify the justifications that nation-states have adopted to regulate the big tech firms and the impacts of this process on international trade in the main economies in the world.

With the massive instrumentation of data, big tech firms have become actors with the capacity to intervene not only in economies but also, above all, in the politics of different countries with different systems. The emergence of big tech firms has transformed the approach to the concepts of national security, information management and access to new technologies among nation-states. The principles and fundamentals of cyber sovereignty have become one of the bases of states in the contemporary system of international relations. Today, the influence of big tech firms in different societies in the contemporary world is one of the main forms of power. This book tries to collect and present the recent state of the art in studies on the relationship between big tech firms and nation-states in the literature. It also addresses how governments such as those of the US, China and the EU are changing their legislation, creating control and data security mechanisms, imposing entry restrictions on foreign companies, and regulating the actions beyond the cloud of big tech firms inside and outside their borders.
