U.S. Companies Warn China’s Critical Minerals Are Nearly Unobtainable as Beijing Tightens Grip on Rare Earth Supply Chains
American companies are now warning that some critical minerals from China are “nearly unobtainable,” and that should alarm every American who cares about national security, manufacturing, defense readiness, and supply-chain independence. This is not just a business complaint about slow licensing or difficult sourcing. It is a direct example of how Beijing can use its dominance over rare earths and critical minerals as leverage against the United States.
According to the Reuters report, the U.S.-China Business Council said American access to China’s critical minerals remains difficult because of export controls and licensing delays. These restrictions were introduced by Beijing in 2025 after U.S. tariffs, and they continue to affect materials crucial to advanced manufacturing. Even after a later agreement in which China reportedly committed to effectively eliminating current and proposed critical mineral export controls, U.S. companies still report low confidence in long-term access.
That gap between China’s promises and corporate reality is the central warning. Beijing may talk about stability, dialogue, and supply-chain cooperation, but American firms are still struggling to secure materials they need. Some rare earth elements remain extremely hard to obtain. Samarium cobalt magnets, important for high-temperature aerospace and defense applications, as well as yttrium and cadmium, were cited as especially difficult for U.S. companies to access. These are not ordinary commodities. They are strategic inputs for aircraft, missiles, semiconductors, advanced electronics, clean energy systems, and defense technologies.
For Americans, the danger is practical and immediate. If China can delay licenses, restrict exports, or create uncertainty around critical mineral access, it can pressure American manufacturers without firing a shot. Factories can slow down. Defense supply chains can face stress. Aerospace production can become more expensive. Semiconductor and clean energy projects can face bottlenecks. The entire U.S. industrial base becomes more vulnerable when Beijing controls the materials needed to build the future economy and modern military systems.
The survey numbers are revealing. Among 38 impacted companies, 29% said they were already shifting to non-Chinese suppliers of critical minerals, while 47% said they were searching for alternatives but had not yet found viable options. That means most affected firms understand the China risk but cannot quickly escape it. This is the trap Beijing’s supply-chain power creates: American companies know they need to diversify, but China’s control over mining, processing, and finished rare earth magnets makes replacement slow, expensive, and technically difficult.
The magnet issue deserves special attention. It is not enough to secure raw minerals if China still dominates processing and finished components. Rare earth magnets are used in defense systems, electric vehicles, wind turbines, robotics, drones, and advanced manufacturing. If the United States depends on China not only for minerals but also for the refined and finished materials that industry actually uses, Beijing retains leverage across the entire production chain.
This case also shows why American companies are becoming more cautious about investing in China. The report notes that only 49% of surveyed companies plan to invest in China this year, reflecting uncertainty in U.S.-China relations and frustration with China’s business environment. Foreign firms face industrial policies that favor domestic companies, preferential government procurement, and a market where formal access can be undermined by political pressure and regulatory unpredictability. China wants foreign investment, but it also wants to protect its national champions and keep strategic leverage.
Americans should understand that China’s critical minerals dominance was not accidental. It is the result of long-term industrial planning, aggressive processing control, and a willingness to use market power for strategic ends. Beijing’s export controls are a reminder that supply-chain dependence can become political dependence. If the United States remains reliant on China for critical minerals, China can threaten American industry, defense, and energy security whenever tensions rise.
The right response is not panic. It is sustained diversification. The United States needs domestic mining where possible, faster permitting, allied supply agreements, mineral recycling, processing capacity, stockpiles, and support for trusted suppliers in countries such as Australia, Canada, Japan, and other partners. Congress, industry, and allied governments all have roles to play because this cannot be solved by one administration or one company alone.
The lesson is clear: China’s threat to the United States is not only visible in warships, cyberattacks, AI chips, or Taiwan pressure. It is also embedded in the materials that power American factories, weapons systems, vehicles, aircraft, and clean energy infrastructure. When U.S. companies say some critical minerals from China are nearly unobtainable, Americans should treat it as a national-security warning. Beijing has already shown it can turn supply chains into weapons. The United States must reduce that leverage before the next crisis makes the cost even higher.
