China's Grip on Rare Earth Minerals: A Looming Shadow Over Global Technology and Geopolitics
The escalating trade tensions between the United States and China have extended beyond tariffs and into a far more critical domain: rare earth minerals. These obscure-sounding elements, despite their misnomer of being 'rare', are anything but insignificant. They are the unsung heroes powering a vast array of modern technologies, from smartphones and electric vehicles to advanced military hardware. China's near-monopoly over the extraction and processing of these vital resources has now emerged as a potent geopolitical weapon, casting a long shadow over global supply chains and national security.
Unpacking the Enigma: What Exactly Are Rare Earth Minerals?
Despite their name, rare earth elements (REEs) are not geologically scarce. They are a group of 17 chemically similar elements in the lanthanide series, along with scandium and yttrium, that are found in various concentrations across the globe. The term 'rare' stems from the fact that they are rarely found in concentrated deposits pure enough for easy and economical extraction. Instead, they are often dispersed in small quantities within other minerals.
While you might not encounter names like Neodymium, Yttrium, or Europium in everyday conversation, you undoubtedly interact with products that rely on them. Neodymium is crucial for the powerful magnets used in loudspeakers, computer hard drives, electric vehicle motors, and jet engines, enabling them to be smaller and more efficient. Yttrium and Europium are essential in the manufacturing of television and computer screens due to their unique color-displaying properties. As Thomas Kruemmer, Director of Ginger International Trade and Investment, aptly puts it:
"Everything you can switch on or off likely runs on rare earths".
– Thomas Kruemmer, Ginger International Trade and Investment
Their applications extend to medical technology, including laser surgery and MRI scans, and are indispensable in key defense technologies. From the most advanced U.S. military fighter jets and missiles to every single cell phone and electric vehicle on the planet, rare earths are vital.
China's Iron Grip: Dominance Across the Supply Chain
China's influence in the rare earth mineral sector is nothing short of a near monopoly. The International Energy Agency (IEA) estimates that China accounts for approximately 61% of rare earth production and a staggering 92% of their processing. This dominance isn't accidental; it is the result of decades of strategic government policies and investment.
In a telling visit to Inner Mongolia in 1992, the late Chinese leader Deng Xiaoping famously declared:
"The Middle East has oil and China has rare earths".
– Deng Xiaoping, 1992
This statement underscored the strategic importance China placed on these minerals early on. Beginning in the late 20th century, China prioritized the development of its rare earth mining and processing capabilities, often with lower environmental standards and labor costs compared to other nations. This approach allowed them to undercut global competitors and build a near-monopoly across the entire value chain, from mining and refining to the manufacturing of finished products like magnets.
The extraction and processing of rare earths are both costly and environmentally challenging. All rare earth resources contain radioactive elements, a significant factor contributing to the reluctance of many other countries, including those in the EU, to engage in large-scale production.
"Radioactive waste from production absolutely requires safe, compliant, permanent disposal. Currently all disposal facilities in EU are temporary,"
– Thomas Kruemmer
explains Mr. Kruemmer. This environmental hurdle, coupled with China's strategic push, solidified its position as the dominant player.
The United States' Achilles' Heel: Dependence and Vulnerability
The extent of the United States' reliance on China for rare earth minerals is stark. The White House states that 70% of U.S. imports in rare earths come from China. A US Geological report corroborates this, noting that between 2020 and 2023, the US relied on China for 70% of its imports of all rare earth compounds and metals. Gracelyn Basker, an economist and director of the minerals security program at the Center for Strategic International Studies (CSIS), emphasizes that the U.S. is "highly dependent on China", particularly because there are no rare earth processing facilities in the U.S.. Even though the U.S. may possess reserves of rare earths, they must be sent back to China for mainstream processing and manufacturing.
This dependence creates a significant vulnerability, especially concerning defense technology. Rare earths are vital for all of our defense technology and civilian uses, from MRI scans to electric vehicles, making the situation "extremely consequential to our security". Specifically, heavy rare earths, which are less common and harder to process than light rare earths, are crucial to the defense sector. According to a CSIS report, defense technologies including F-35 jets, Tomahawk missiles, and Predator unmanned aerial vehicles all depend on these minerals. This vulnerability is amplified as China "expands its munitions production and acquires advanced weapons systems and equipment at a pace five to six times faster than the United States". Mr. Kroemmer believes that "the impact on the US defence industry will be substantial".
Beyond defense, US manufacturing, which the Trump administration aimed to revive through tariffs, stands to be severely impacted. Dr. Harper warns that "manufacturers, particularly in defence and high-tech, face potential shortages and production delays due to halted shipments and limited inventories". Furthermore, "prices for critical rare earth materials are expected to surge, increasing the immediate costs of components used in a wide range of products, from smartphones to military hardware," potentially leading to production slowdowns for affected US companies.
Rare Earths as a Weapon: A History of Geopolitical Leverage
The prospect of China using its dominance in rare earths as a geopolitical weapon is not a new one. Rare earths have often been weaponized. A notable instance occurred in 2010 when China and Japan were embroiled in a fishing trawler dispute, and Japan faced a cut-off of rare earth exports. This event served as a stark reminder of China's capacity to leverage its mineral resources for political gain.
More recently, as the trade war with the U.S. intensified, Beijing began restricting the export of rare earth and magnets that are almost entirely refined by China. These restrictions are seen as a direct response to U.S. pressure when it comes to trade. While not an outright ban initially, China implemented a system of non-automatic licensing, requiring companies to apply for permits to export these minerals. This pause in exports while they get a license system in place acts as an immediate disruption. Gracelyn Basker explains that a licensing requirement is a dynamic tool, allowing China to control who gets licensed and how much they are licensed to export, giving them significant negotiating power. Furthermore, these restrictions could be tightened quite significantly as the trade war escalates, potentially leading to an ultimate ban. Notably, 15 defense aerospace companies are reportedly no longer able to access dual-use goods from China, which could include rare earths.
China's actions are viewed by some as a carefully calculated "shot across the bow". The export controls initially targeted heavy rare earths, critical minerals, and rare earths, where 100% of separations are done in China. What became apparent later was that the restrictions also included actual magnets and products shipped to the United States, raising significant concerns within the defense community. The earlier imposition of export controls on gallium and germanium served as a prior warning, with one senior White House official stating that it was the moment "when everybody finally got it and understood how serious this was". China's policymakers are perceived as "incredibly sharp", knowing precisely "what impacts what and when".
The Impact on the US: Navigating Uncertainty and Dependence
China's move to curb rare earth exports poses a multi-faceted challenge to the United States. The most immediate concern is the potential disruption to the supply chain for critical industries, particularly defense and high-tech manufacturing. Halted shipments and limited inventories could lead to potential shortages and production delays. The surge in prices for these essential materials would further exacerbate the issue, increasing the immediate costs of components used in a wide range of products.
The restrictions also highlight the precariousness of the U.S.'s reliance on a single dominant supplier, especially in a context of escalating geopolitical tensions. While the current measures involve licensing rather than a complete ban, the potential for further tightening of these restrictions creates significant uncertainty for U.S. companies. As Gracelyn Basker notes, given the few facilities outside of China capable of providing the necessary rare earths, these restrictions could ultimately undermine U.S. national security, economic security (through impacts on semiconductors), and energy security (due to their use in energy technologies).
Seeking Alternatives: A Long and Arduous Path
Recognizing the strategic vulnerability posed by its dependence on China, the U.S. has begun exploring alternatives. President Trump launched a new national security investigation that could lead to tariffs over critical minerals and ordered the commerce department to find ways to boost US production of critical minerals and cut reliance on imports.
Efforts are underway to invest in facilities within the U.S. to establish domestic mining and processing capabilities. The U.S. government has invested over $400 million through the Defense Production Act over the last five years towards this goal. Facilities are being built in places like Texas and Canada. However, these efforts face significant hurdles. Gracelyn Basker points out that "we will probably not decouple any time soon". While the U.S. has been mining rare earths for some years, it never built separation facilities. Even with the recent investments, these facilities are not ready to go and, when they do come online, they will only produce a small fraction of what China produces.
Furthermore, geology presents another challenge, with the U.S. possessing less than 1.5% of the world's rare earths reserves. This necessitates a foreign policy strategy to secure rare earths from other countries. Potential sources include South Africa, Brazil, Ukraine, and Greenland. However, securing these supply chains is not without its complexities, involving time, capital, and considerable willpower.
Moreover, the U.S.'s "adversarial tone" and "antagonising many nations that have previously been friendly collaborators through tariffs and other hostile actions" could hinder its ability to forge new partnerships.
China's Strategic Calculus: More Than Just Retaliation
While China's export restrictions are undoubtedly a response to trade pressures from the U.S., they also reflect a broader strategic calculus. By leveraging its dominance in critical minerals, Beijing aims to exert influence in the ongoing trade negotiations. The restrictions serve as a potent negotiating tool, giving China power in a tariff war because they have an absolute advantage. The idea is that this leverage could eventually lead to tariffs coming back down to a more reasonable level, ensuring China's continued economic growth while also guaranteeing U.S. access to critical materials, albeit on China's terms.
Furthermore, China's actions align with its long-term ambition to establish itself as a leading global power in technology and manufacturing. By controlling the supply of essential minerals, China can strategically influence the development and deployment of future technologies, ensuring its continued dominance in key sectors. The Southeast Asia tour of Chinese leader Xi Jinping, portraying Beijing as a "benevolent source of regional stability" and advocating for "joining hands rather than throwing punches" and "connecting instead of decoupling", underscores China's efforts to build alternative partnerships and reinforce its global standing.
Conclusion: A Future Defined by Rare Earths
China's strategic control over rare earth minerals has emerged as a critical factor in the complex and evolving relationship with the United States. These seemingly inconspicuous elements hold immense power, underpinning essential technologies and shaping the geopolitical landscape. While the U.S. is belatedly recognizing its vulnerability and initiating efforts to diversify its supply chains and bolster domestic production, the path to reducing dependence on China is long and fraught with challenges.
The ongoing trade war has illuminated the extent to which critical mineral supply chains can be weaponized, forcing nations to confront their dependencies and reassess their strategic priorities. As the world increasingly relies on technologies powered by rare earths, China's dominant position ensures that these minerals will remain at the forefront of global economic and political discourse, casting a looming shadow over the future of technology and international relations. The ability of the U.S. to secure alternative supplies and build resilient domestic capabilities will be crucial in navigating this new era of resource competition and safeguarding its national security and economic prosperity.
