On the Current State of Research
The United States’ perception of China as a revisionist strategic rival will complicate transatlantic policy coordination.
If the economic interdependence between the United States and China dissolves, economic blocs or closed economic spaces emerge and a process of economic de-globalization begins. In the course of such a bipolarization of the international system, Europe would find itself in a difficult situation.
