Washington’s debate on critical minerals has become fixated on one question: How can the US reduce its dependence on China without replacing one strategic vulnerability with another? An answer has recently emerged far from Beijing, Washington, or the cobalt mines of southern Congo. It is in Burundi, a country with a roughly $4 billion economy, whose geopolitical importance is now expanding far faster than its fiscal capacity.
In March, this year, Burundi signed agreements at the US State Department with Lifezone Metals and KoBold Metals, the exploration company backed by Jeff Bezos and Bill Gates. The projects center on Musongati, where more than 140 million tonnes of nickel-bearing ore are estimated to also contain copper, cobalt, gold, platinum-group metals, and scandium. A single deposit potentially equivalent to roughly 6 percent of global nickel reserves has suddenly acquired significance well beyond Burundi’s borders.
The timing matters. While Washington was courting Burundi as a potential alternative node in critical mineral supply chains, Burundian soldiers were fighting alongside Kinshasa against Alliance Fleuve Congo-March 23 Movement forces in eastern Democratic Republic of Congo. More than 29,000 Burundian troops reportedly entered eastern Congo between August 2022 and December last year, with others deployed simultaneously in South Kivu. Burundi has consequently acquired something rare for a state of its size: geopolitical bargaining power generated by the intersection of geology, geography, and military necessity.
Burundi is East Africa’s second-largest holder of coltan, a mineral containing the elements tantalum and niobium indispensable to the manufacture of modern electronic devices. It also accounts for roughly 2 percent of global tantalum production, and while its formal mining output remains small, its position astride the Bujumbura-Bukavu-Uvira corridor gives it importance as a conduit for highly sought-after Congolese minerals. Traceability can document declared supply chains; it cannot, by itself, eliminate the commercial incentives surrounding informal cross-border flows.
Washington and Doha, meanwhile, have constructed peace architecture around an incomplete map of the war. The December 2025 Washington Accords address Rwanda and the DRC; the Doha process addresses Kinshasa and AFC/M23. Burundi occupies the missing space between them, despite becoming a major foreign military actor in South Kivu.
For Burundi’s President Evariste Ndayishimiye, the calculus is existential. The Ruzizi Plain and Uvira sit dangerously close to Bujumbura’s economic core. Every battlefield shift toward the Burundian frontier, therefore, shortens the distance between Congo’s war and Burundi’s domestic security. The resulting feedback loop is difficult to ignore. Insecurity justifies intervention; intervention creates military exposure; mineral diplomacy creates international protection; and international demand for alternative supply chains can make continued intervention easier to sustain.
Moreover, the most consequential implication lies in the incentives created by emerging Western supply chain policy. A government that becomes useful to Washington because its territory contains strategically valuable minerals can acquire diplomatic room that exceeds the conventional weight of its economy. For Gitega, mineral diplomacy consequently has the potential to become a form of strategic insurance: External investors need political predictability, while policymakers seeking alternatives to Chinese supply chains need new projects capable of surviving geopolitical competition.
Economic geography magnifies the effect. Musongati is not an isolated geological prospect existing outside regional conflict dynamics. Burundi’s mineral corridors connect directly to eastern Congo’s commercial networks, ports on Lake Tanganyika, and the trading centers around Bujumbura, Bukavu, and Uvira. Every improvement in roads, customs systems, geological mapping, energy supply, and export infrastructure can lower the cost of legitimate mineral production and increase the value of the territorial corridors through which armed actors, commodities, and influence move.
