What happened
A UK parliamentary business select committee has released a report characterizing the nation’s reliance on China for critical minerals as a 'dangerous' strategic vulnerability. The committee, chaired by Liam Byrne, found that China maintains a dominant position in the refining of minerals essential for high-tech sectors, including AI hardware, military aircraft, and renewable energy infrastructure. The report highlights that demand for lithium is projected to increase 45-fold by 2030, while demand for rare earths used in military applications is expected to rise 16-fold. The committee criticized the government for a lack of transparency regarding its risk-mitigation strategies and proposed a 10-point plan to secure supply chains, including domestic mining, recycling, and international partnerships.
The UK business select committee report identifies critical minerals as the 'alpha' of the modern economy, noting that AI, net-zero technologies, and military rearmament are all dependent on a supply chain currently dominated by China.
The committee highlighted that the primary bottleneck exists at the 'processing stage,' where China controls the refining of seven major mineral categories, including lithium and rare earths used in high-performance military components.
MPs expressed frustration with the government's lack of transparency, stating that Parliament has no visibility into the specific capabilities the government is attempting to protect or the projects currently receiving backing.
The committee proposed a 10-point plan to reduce dependency, which includes identifying domestic mining opportunities, streamlining planning and permitting processes, and creating a dedicated finance facility to support new supply sources.
A government spokesperson defended existing efforts, citing a £400 million investment in domestic production and recycling, and reiterated a goal to ensure no more than 60% of any critical mineral comes from a single country by 2035.

Why it matters
The findings underscore the physical supply chain constraints that underpin the global AI boom. While much of the discourse surrounding AI focuses on software and capacity, this report highlights that the hardware required for AI—and the military systems that increasingly integrate it—is tethered to a concentrated global supply of refined minerals controlled by China. The committee’s warning suggests that the UK’s ability to scale AI infrastructure and maintain defense capabilities is currently at the mercy of geopolitical tensions. If China were to restrict exports, as it has done previously, the UK’s technological and security ambitions could face immediate, severe bottlenecks. The report emphasizes that current government efforts are insufficient to decouple from this dependency, leaving the nation exposed to the volatility of US-China trade relations and potential supply cut-offs. This highlights a critical, often overlooked 'choke point' in the AI value chain that could dictate the pace of future development.
The report frames AI development not just as a software challenge, but as a material one. Without a secure supply of refined rare earths and lithium, the physical infrastructure required for AI—such as advanced chips and data center hardware—cannot be sustained.
The dependency creates a strategic vulnerability where the UK's technological progress is subject to the geopolitical whims of Beijing. The committee noted that China has previously weaponized its supply chain, creating risks for both the economy and national security.
The reliance on US-China diplomatic reprieves, such as the one secured by Donald Trump in 2025, highlights that the UK lacks independent leverage in securing these essential materials, making its AI and defense sectors 'at the mercy' of larger global powers.
The committee's skepticism regarding the government's current strategy suggests that existing policies may be inadequate to meet the projected 16-fold to 45-fold increase in demand for these minerals by 2030.

What to watch next
The primary focus will be on whether the UK government adopts the committee’s recommendation to establish a 'critical minerals finance facility' to incentivize domestic mining and refining. Observers should monitor if the government adjusts its 2035 targets—which currently aim for 60% maximum reliance on any single country—in response to the committee's skepticism. Additionally, the report notes that the UK’s current supply security is effectively tied to the stability of US-China relations, specifically regarding export reprieves that expire in January 2027. Any shifts in these diplomatic agreements will directly impact the availability of materials required for the UK’s AI and defense sectors.
Watch for the government's formal response to the committee's 10-point plan, specifically whether they commit to the proposed 'critical minerals finance facility.'
Monitor the January 2027 expiration of the current US-China export reprieve, as this date serves as a critical juncture for the stability of global mineral supplies.
Track any legislative changes to UK planning and permitting processes, which the committee identified as a significant barrier to developing domestic mining and refining capabilities.
Observe whether the government provides more granular data on its 2035 targets to address the committee's concerns regarding transparency and the current lack of visibility into risk-mitigation projects.
