In this chapter, we seek to answer the question of if—and if so: how—the Russian and Chinese receptions of the Großraum concept developed by Carl Schmitt in 1939/41 intersect and reinforce each other at critical junctures. If they turn out to do so, this will help us understand what the accumulated threat of Großraum thinking is today in its competition with liberal modes of thinking non-intervention in international law. We conclude that the pattern of Russian and Chinese practices that we have surveyed is not reducible to a single or clear-cut Schmittian Großraum model. On the basis of our survey, a Großraum mode of arguing international law cannot be said to have grown to such a degree that it threatens the dominance of liberal accounts of international law. That said, Schmitt’s Großraum theory remains helpful for understanding, in part, the international legal behavior of Russia, and to some degree also that of China. We suggest that further engagement and analysis are needed.
