The Group of Seven nations is working on a plan to limit China's share of the global rare earths market to 60 percent. The move targets the critical minerals that power everything from smartphones to electric vehicles and military hardware. It's an attempt to reduce the West's reliance on Beijing for materials that have become a strategic vulnerability.
Why the G7 is targeting rare earths
Rare earth elements are a set of 17 metals with names like neodymium, dysprosium, and praseodymium. They're essential for magnets in wind turbines, electric car motors, and missile guidance systems. China currently dominates the mining and processing of these materials. The G7's cap would set a ceiling on that dominance, forcing other countries to develop their own supply chains or find alternative sources.
The proposal suggests the G7 sees China's current share as too high for comfort. Without a limit, one country would hold an outsized influence over industries that are critical to both economic competitiveness and national security. The cap is designed to create space for new players to enter the market.
What the cap means for supply chains
If the 60 percent limit is enforced, it won't happen overnight. The G7 will need to invest in mining projects and processing facilities outside China. That means building new mines, refineries, and separation plants — all of which take years to get up and running. It also means working with countries that have rare earth deposits but haven't fully developed them.
The plan could accelerate recycling efforts. Rare earths are hard to extract, but they're also hard to replace. Recycling from old electronics and magnets could help reduce the need for new mining. But right now, recycling rates are low. The G7's push might change that by providing funding or setting targets.
Companies that rely on rare earths will be watching closely. A cap could mean higher prices in the short term as supply chains adjust. But it could also mean more stable supplies in the long run if the G7's diversification strategy works.
Possible responses from Beijing
China isn't likely to sit still. It could restrict its own exports of rare earths or impose taxes on shipments abroad. That would hurt global buyers and give China leverage in trade talks. Beijing has used export controls before, most notably on gallium and germanium last year. A similar move on rare earths would be a direct response to the G7's plan.
China could also ramp up its own consumption of rare earths, using them to build more products at home rather than selling raw materials overseas. That would shrink the global supply pool and drive up prices, making the G7's diversification effort more urgent and more expensive.
The plan doesn't specify how the cap would be enforced. That's a big question mark. Would the G7 impose tariffs on rare earths that exceed the limit? Would it block Chinese companies from buying mines abroad? The details matter, and they're not yet public.
The proposal is expected to be a topic at the next G7 leaders' summit, though no date has been set. In the meantime, member countries will have to figure out how to turn a politically appealing idea into a workable policy. That's where the hard part begins.
