This book defines Eurasianism, a political idea with a long tradition, for a new century. Historically, Eurasia was depicted as a "third continent" with a geographical and historical space distinctively different from both Europe and Asia. Today, the concept is mobilized by the Russian foreign policy elite to imagine a close relationship with China and indirectly inspires the Chinese Belt and Road Initiative. A Russian-Chinese partnership forms the core of a new Eurasian region, yet Turkey, India, Hungary, Central Asia and the other parts of the supercontinent are also embracing Eurasian concepts. This book is of interest to scholars of Russian and Chinese foreign policy, to economists, and to scholars of political thought.
