This open access edited book brings together a closer examination of European and Asian responses to the escalating rivalry between the US and China. As the new Cold War has surfaced as a perceivable reality in the post-COVID era, the topic itself is of great importance to policymakers, academic researchers, and the interested public. Furthermore, this manuscript makes a valuable contribution to an under-studied and increasingly important phenomenon in international relations: the impact of the growing strategic competition between the United States and China on third parties, such as small and middle powers in the two arguably most affected regions of the world: Europe and East Asia. The European side has been under-studied and explicitly comparative work on Europe and East Asia is extremely rare. Given that the manuscript focuses heavily on recent developments—and because many of these developments have been quite dramatic—there are very few publications that cover the same topics.
