Mundane Geopolitics, Strategic (De)Coupling, and Chinese Infrastructure Investment in Europe

Giles Mohan, Weiwei Chen, Philipp Katsinas, Florian Schaefer

Geopolitical rivalry between China and the US is profoundly affecting transnational investments. We develop an analytical framework that augments the notion of strategic coupling to capture whether and how transnational investment projects can cohere in a geopolitically charged world. Two cases—Duisburg in …
