A Warning That Lands Close to Home
Few sentences in British public policy carry as much weight as the one a parliamentary committee has now put on record: the United Kingdom is “dangerously” dependent on China for the raw materials that modern life quietly depends on. The business select committee’s investigation, led by Liam Byrne, argues that the same minerals needed to rebuild the armed forces, power wind turbines and electric vehicles, and run the chips behind artificial intelligence, are concentrated in a single country that has already shown it is willing to switch supply on and off.
The report’s language is blunt. Byrne described critical minerals as “the alpha of the new economy” and warned that Britain cannot rearm, build AI or deliver net zero without securing them. Those are big claims, but they rest on a simple problem. China does not just mine many of these resources. It dominates the refining stage, the unglamorous chemical processing that turns raw ore into something a factory can use. That is where the bottleneck sits, and it is where most Western governments have been slowest to build capacity.
Why Demand Is About to Explode
The numbers presented to MPs help explain the urgency. Demand for lithium is forecast to rise roughly 45-fold by 2030, while rare earths used in permanent magnets, the kind found in military jets, electric motors and wind turbine generators, are expected to grow around 16-fold over the same period. Those magnets matter far beyond defence. They sit inside the motors of electric cars, the generators of offshore wind farms and a long list of consumer appliances, from washing machines to hard drives.
China’s leverage has been demonstrated before. Beijing restricted rare earth exports in 2025, and a separate dispute over legacy semiconductors pushed European car manufacturers to the edge of production stoppages. A one-year reprieve on global rare earth export restrictions, agreed between Donald Trump and Xi Jinping and later extended to January 2027, offers breathing room. But as the committee points out, it also ties British supply security to the shifting temperature of US-China relations, which is not a position any government would choose.
What Britain Is Doing, and What Critics Say It Should Do
The government insists it is not standing still. It points to £400 million earmarked to expand domestic production and recycling, new international partnerships, and targets for 2035 that include meeting 10 per cent of demand from domestic production, 20 per cent from recycling, and capping dependence on any single country at 60 per cent. Those are meaningful ambitions, but the committee argues they lack the institutional muscle to deliver. Its proposals include a dedicated critical minerals finance facility, a 10-point plan covering domestic mining and refining, incentives for businesses to shift procurement away from China, and a review of planning rules that can slow new mines for years. The committee also complained that Parliament has little visibility into which capabilities are being protected and which projects are receiving backing.
Its most practical suggestion may be working with G7 partners, Europe and Indo-Pacific allies to pool demand. Buyers acting alone have little bargaining power. Buyers acting together can attract new suppliers, justify investment in refineries and spread the financial risk of projects that would otherwise never clear the bar.
For consumers and businesses, these geopolitical debates can feel distant, yet they shape what gets built and what it costs. Battery prices, the availability of electric vehicles, the pace of home energy upgrades and even the performance of the AI tools now appearing in everyday software all trace back to these supply chains. When rare earth exports tighten, device makers feel it first, and buyers tend to see higher prices or longer waits. As the UK pushes to electrify transport and expand AI services, shoppers evaluating a new car, a heat pump or a laptop may find that the supply chain behind each product is becoming a more important part of the buying decision than it once was.
