Abstract

The current geopolitical scenario of rare earth elements (REEs) is determined by structural supply chain asymmetry, energy transition mandates, and strategic competition. Due to significant land degradation and pervasive externalization of environmental costs in its domestic extractive economy, the People's Republic of China (PRC) retains almost complete control on midstream REE separation (91%). Beijing’s capacity to weaponize export regulations to threaten partner defense and green technology industries is based on this competitive advantage, which stems from ecological non-compliance. As seen by the EU's Critical Raw Materials Act (CRM Act) and the Minerals Security Partnership (MSP), Western policy solutions aim to develop strong, ethical supply alternatives. The growth of the Middle East and North Africa (MENA) region, propelled by Saudi Arabia's high-capital Vision 2030 programs, is an important test case for effectively decoupling strategic inputs from single-state dependency and for creating a new, ESG-compliant processing architecture.

I. Introduction: The Crystallization of Strategic Vulnerability

The growing degree of rivalry among big powers and the global demand for decarbonization have made REEs, a collection of 17 metallic elements, an important part of strategic geology in the twenty-first century. Neodymium (Nd), Praseodymium (Pr), and Dysprosium (Dy), among others, represent the building blocks of excellent-performing Neodymium-Iron-Boron (NdFeB) permanent magnets.These magnets are crucial components of clean energy infrastructure, including direct-driven wind turbines and high-performance electric vehicle (EV) motors, with demand predicted to increase by several hundred percent by 2035 assuming current climate scenarios.

In the defense industry, REEs are also strategically crucial. The technological edge of allied armed forces is severely compromised by reliance on these commodities.Sophisticated equipment such as nuclear-powered submarines (which use 4.6 tons) and Tomahawk missiles (which need more than 400 kg of REEs) are highly reliant on Chinese-controlled inputs, thereby making the supply exposure significant. This twin vulnerability, including maintaining military primacy while facilitating the energy transition, defines the geopolitical criticality of REE control.

China's market dominance is the product of four decades of deliberate strategy.During the 80s and 90s of the last century, the PRC took advantage of low-cost domestic energy by obtaining and enhancing foreign processing skills. While the rest of the world concentrated on cutting costs and allowed the shutdown of regional mines like Mountain Pass, California, Beijing systematically developed and strengthened a state-owned domestic supply chain.The resulting supply asymmetry still poses a significant strategic risk to nations that strongly rely on technology, even though mine production has diversified globally (China currently generates around 60% of it).

The Geopolitics of Environmental Externalization: China’s Strategic Land Use

Beyond volume concentration, the most significant structural weaknesses in the international REE supply chain is represented by the technological mid-stream processing bottlenecks and the underpinning economic paradigm that created it. What captures our attention is that China controls 91% of the world's capacity for separation and refining. This process, which constitutes the most critical bottleneck in the entire production value chain, requires specific solvents and complicated infrastructure due to its high chemical and technological demands. This domination was cemented by a model of unrestrained mineral extraction and environmental externalization. Because of the country's remarkably low environmental enforcement, Chinese businesses have generally been enabled to avoid the substantial investment costs and long-term rehabilitation expenses which their western competitors face.

Ma Jun, chairman of the Institute of Public and Environmental Affairs in Beijing, claims that the cost of environmental infractions in China is "way too low." Consequently, low-cost exports of resources occur, and a significant portion of the ecological burden is passed on to local communities. The physical toll on the land showcases the magnitude of this externalization. Namely, the rare-earth elements processed at Baotou (a city in inner Mongolia), the biggest rare earth mine in the world, provides 37.8% of the world's reserves and 83.7% of the nation's reserves. The biggest open-pit mine, a massive black crater 48 square kilometers in size and 1,000 meters deep, is a visible record of the scope of "land exploitation." NASA published satellite photos of the region in 2012, revealing it as among several massive craters that overshadow an apartment complex straight to the south.

The lack of environmental controls also resulted in devastating localized contamination; a neighboring villager reported seeing polluted sheep next to the mine, manifesting with two rows of teeth so long the animals could not close their mouths.The PRC's uncontrolled, low-cost production process has proven to be a powerful economic instrument. The financial advantage of not having to adhere to stringent ESG regulations allows Chinese local manufacturers to operate with cheaper overheads than their foreign rivals.

Western firms often have to pay estimated expenses for REE which can be up to 31% more than their Chinese rivals. This structural advantage serves as the foundation for the current geopolitical influence. Following a 2014 World Trade Organization (WTO) finding that China's export quotas and levies breached international trade norms, Beijing modified its strategy for controlling technology and highly processed resources.

Recent, more stringent export laws target the technical data required to manufacture permanent magnets and processed rare earth components, particularly those with only trace Chinese content. Limiting the military, semiconductor, and AI industries' technological capabilities in the US and its allies, gaining leverage in trade negotiations, and retaliating against partner technology limitations represent the primary objectives. This savvy use of supply restriction shows that whoever controls the ecologically expensive manufacturing of REEs holds the gate towards the advancement in highly advanced technology.

Diversification and the MENA Strategic Pivot

Realizing that it is not feasible for countries to contend with a state-backed scheme for environmental externalization just on the basis of price, Western nations have embarked on coordinated efforts to develop robust and ethically good alternative supply chains. The Minerals Security Partnership (MSP), comprising 15 nations and the European Union, seeks to expedite important projects across the whole value chain by mobilizing public and private finance.

Furthermore, by 2030, based on the EU's CRM Act, no country will be allowed to supply more than 65% of the EU's annual consumption of any key raw material, implying that 10% of extraction demands, 40% of processing requirements, as well as 25% of recycling needs need to be met by domestic capacity. To achieve these diversification goals, significant investment in newly constructed non-Chinese processing plants that strictly adhere to global ESG standards is required.

The MENA region is strategically positioning itself to address this need by leveraging its financial resources and geographic location. Saudi Arabia, specifically as part of its Vision 2030 framework, is utilizing its vast mineral endowments and deep sovereign cash to develop a whole REE value chain, starting from extraction to permanent magnet production. The state-owned Saudi Arabian Mining Company (Ma'aden) is exploring the possibility of collaborating with global technological experts including MP Materials (U.S.), Lynas Rare Earths (Australia), and Neo Performance Materials (Canada) to acquire the necessary midstream processing expertise. Early in its mineral diplomacy plan, the United States prioritized cooperating with Saudi Arabia because of the Saudi kingdom's potential to become a dependable, financially backed, and strategically positioned center for critical minerals.  This shift became official with the Memorandum of Cooperation (MOC), which came into force with the United States in May 2025. It outlines a framework for joint exploration and processing with the goal of ensuring and strengthening crucial mineral supply chains that are essential to advanced manufacturing and defense. The goal of Vision 2030, which aims to use the country's $2.5 trillion mineral riches to grow the mining industry to $75 billion by 2030 and establish the kingdom as the leading global center for rare earth processing by 2027, is directly supported by this diplomatic arrangement.

This partnership structure has been validated by recent geopolitical study. Saudi Arabia, with an overall rating of 2.6/3.0, is among the top nations in the world for creating a cost-efficient processing hub, alongside the US (2.7/3.0) and Australia (2.6/3.0).The assessment was based on an extensive examination of rare-earth processing jurisdictions and the full list of parameters summarized in the matrix below. These are the most promising candidates for developing new midstream processing hubs.

This multinational approach is essential, as the analysis concludes no single country possesses all the necessary factors to independently establish a fully competitive and resilient rare earth supply chain.

The success of the MENA pivot depends on two important factors: first, its capacity to sustain a stable regulatory setting and low political risk necessary to attract sustained capital from private investors for capital-intensive, lengthy-term projects; based on to the Fraser Survey from 2023, political stability turned out a significant factor for over 50% of Canadian and Australian respondents when considering investment jurisdictions; and second, its commitment to maintaining rigorous ESG standards with the objective to establish a truly ethical alternative supply that does not resemble China's exploitative model.

Conclusion

The geopolitical conflict over REE shows that the basis of strategic dominance is technological proficiency in complex processing, which China developed by externalizing environmental and social burdens. To counter this dominance, an integrated strategy based on three pillars is required: broadening midstream processing via sovereign capital-backed nodes in important regions like MENA; tightly implementing international ESG standards in order to establish a predictable alternative; and accelerating circularity and technological substitution. Alternative extraction, ethical processing, and breakthrough technologies must work together to reduce the serious hazards associated with the current REE structure and ensure a secure future for high technology.  To what degree will we permit a single, costly supply chain to power global technology in the future?
