International Capacity Cooperation is China’s policy answer to comparative advantage, a vast state-planning exercise to coordinate China’s trade and investment strategy in external geographies. It is the practical industrial policy matrix allowing industries, local governments, and policy banking to intersect with partner economies as part of the wider geoeconomic Belt and Road strategy. For China’s aluminum sector, which is already heavily state subsidized and widely considered to be dumping on international markets, it represents an opportunity to extend the lifespan of the industrial policy and policy bank model. The formation of an aluminum capacity cooperation enterprise alliance should be a warning signal to the non-ferrous metals industries of China’s trading partners in Central Asia.
