The UK business select committee has laid out what amounts to a strategic indictment: Britain remains acutely dependent on China for the critical minerals underpinning its military, energy transition, and AI ambitions, and has no functioning plan to change that. The committee's 10-point test found the government could not satisfy any of them. The language is unusually blunt for a parliamentary report — "dangerously exposed" — and committee chair Liam Byrne framed critical minerals as "the alpha of the new economy." The dependency is not abstract. China dominates refining across seven categories of minerals, including lithium for electric vehicles and rare earths used in military aircraft fuselage and wing structures. Demand for lithium is projected to increase 45-fold by 2030; demand for rare earths used in permanent magnets for military jets is set to rise 16-fold. The UK has no meaningful domestic production, refining capacity, or recycling infrastructure to absorb even a fraction of that demand. The chokepoint was demonstrated in 2025 when China cut off rare earth exports. A separate row over the Dutch intervention in China-owned Nexperia triggered legacy chip restrictions that brought the European car industry to within days of production stoppages last October. These are not hypothetical risks — they are recent events with documented economic consequences. The current reprieve on rare earth export restrictions exists only because Donald Trump negotiated a one-year deal with Xi Jinping, since extended to January 2027. Britain's supply security is therefore a derivative of the US-China relationship — a position no serious defence posture can tolerate. The committee noted that Parliament has "no visibility" of what the government is actually doing to reduce risk. The government's response — citing £400m for domestic production and recycling, plus 2035 targets of 10% domestic production, 20% recycling, and no more than 60% from any single country — reads as aspiration rather than strategy. A 60% cap from a single source is not diversification; it is formalised dependency. The committee's recommended "critical minerals finance facility" with grants, equity, and debt instruments would represent genuine institutional infrastructure, but no such entity exists. The realistic path, as the committee identifies, runs through G7, European, and Indo-Pacific partnerships to aggregate demand and bring in new suppliers. This is the only approach that matches the scale of the problem. Domestic mining and recycling will help at the margins, but no single Western economy can replicate China's 30-year head start in extraction and processing alone. The structural question is whether Westminster treats this as a genuine national security priority or as another policy area where targets substitute for action. The 2035 horizon is a decade away. The 45-fold lithium demand increase is five years away. The gap between those timelines and the current institutional capacity is where the real risk lives.
