It has been known since at least 2010 that China has been seeking a monopoly on certain critical minerals, and that it would also be willing to use this monopoly for the purposes of economic coercion. That was the year Beijing first deployed this weapon by restricting exports of rare earths to Japanese companies at a time of political tension between the two countries. There has been ample time since then for other nations in Beijing’s crosshairs to have developed alternative capacities. Unfortunately, despite various new policy missions being developed in multiple nations, as well as a large pot of money being set aside by the previous administration in the US, China’s effective control over this supply chain continues. American companies, in particular, have been unforgivably lazy about building up vital stockpiles to deal with disruption in supply. The global implications of this might be dire. The car companies switching to electric vehicles will particularly struggle to obtain vital magnets. Manufacturers of drones, robotics, and missiles will also find their supply chain compromised, which will significantly affect Western military readiness — especially at a time when arsenals are being built up across Europe as a consequence of the Ukraine war and transatlantic tensions.
