Highlights
- A comprehensive study shows geopolitical cooperation significantly impacts rare earth trade networks.
- Cooperative countries experience up to 5.4-fold trade relationship amplification.
- Conflict-prone nations face trade suppression up to 25%.
- The midstream processing segment is most sensitive to geopolitical tensions.
- Nations must prioritize diplomatic strategies, regional cooperation, and industrial alliances.
- Efforts are needed to secure reliable rare earth access in an increasingly complex global market.
In a sweeping quantitative analysis of 140 nations and two decades of global trade, lead author Chunxi Liu of Jiangxi Normal University (opens in a new tab) (China) delivers a sobering insight: geopolitical cooperation and conflict—not simple resource availability—now govern the structural evolution of rare earth trade across upstream mining, midstream processing, and downstream magnet production. Published in Sustainability (May 2025), the study deploys a temporal exponential random graph model (TERGM) to map rare earth dependency networks between 2001 and 2023. Its core finding? Countries with high centrality in geopolitical cooperation networks see a dramatic amplification—up to 5.4-fold—in their rare earth trade relationships, particularly at the midstream level. Conversely, conflict-centric nations face trade suppression up to 25%, especially where technological exchange is critical.
The study dismantles the outdated assumption that rare earth trade is simply about comparative advantage in raw materials. Instead, it reveals a bifurcated world: cooperative hubs, such as the U.S., China, and Germany, anchor dense, resilient trade webs, while conflict-prone states risk isolation and market attrition. For commercial stakeholders, the implications are profound. Supply chain diversification is not merely a function of mine openings or refinery investments—it is also a function of diplomatic posture and geopolitical alignment. In short, alliances matter. Particularly vulnerable is the midstream segment—separation and oxide production, which the data show to be the most sensitive to geopolitical tensions. A 1-point rise in conflict eigenvector centrality (i.e., being more connected to global disputes) erodes midstream trade probabilities by a staggering 25.1%.
For commercial supply chain actors and government planners, this paper changes the game. It confirms that rare earth resilience strategies cannot rely solely on technical workarounds like recycling or magnet substitutes.
Rather, nations must prioritize geopolitical risk mitigation, regional cooperation agreements, and industrial diplomacy to secure reliable access to rare earths. The U.S., EU, and allied nations now face a choice: deepen trust-based trade networks with one another, or risk watching the center of gravity in rare earth governance continue to shift eastward. The Liu study offers hard evidence that the rare earth war will not be won with mines alone—but with alliances, standards, and strategy.
