In 1973 a club of Arab petrostates held the world to ransom by halting crude-oil exports to countries they accused of supporting Israel. Petrol prices soared; Western economies buckled. Today the danger is that China will use its grip on other natural resources to achieve its aims, such as seizing Taiwan. It has already shown its power by choking off exports of rare-earth metals last year. That is why America is staging its biggest intervention in commodity markets in decades.
The battleground is the supply of “critical” metals, a group of minerals vital to making military, electrical and computing infrastructure—everything modern economies need to be safe, high-tech and green. China supplies most of these: it mines about 80% of the world’s tungsten, for instance, and refines 99% of its gallium. This is spurring America into an all-out campaign to diversify its sourcing of 60 minerals. It has pledged billions of dollars to dozens of mining projects at home and abroad, floated plans to create price floors and trade blocs, and announced a vast stockpile to cover months of national needs. The risk now is that America depends too much on its scattershot efforts—and that, in seeking control, it breaks the flexible and resilient system of market incentives that ensures the smooth functioning of the global economy.
China’s grip on critical minerals has exposed the West’s most serious strategic weakness in many years. Last April, during its trade war with America, China restricted exports of seven crucial rare earths; it targeted another five in October. Nearly a third of Pentagon procurement programmes faced the risk of shortages, as did industries from carmaking to renewable energy. The prospect of large-scale disruption prodded President Donald Trump into a trade truce with Xi Jinping, as well as a relaxation of American controls on some technology exports. Yet Mr Xi can deploy the weapon again whenever he chooses. Meanwhile, exports of rare earths for dual-use applications—the expanding grey zone between military and civilian uses—remain largely barred, sapping Western efforts to rearm….
America is racing to break China’s chokehold on critical minerals—but its approach has flaws. It should follow three principles https://t.co/t5SkUsYgjf pic.twitter.com/BgoWViJBZv
