The United States has formalized a strategic minerals agreement with Colombia, marking another significant step in Washington's effort to reduce dependence on Chinese supply chains for critical raw materials. On September 8, 2026, U.S. Secretary of State Rubio and Colombian Foreign Minister Bula signed the "Framework Memorandum of Understanding on Critical Minerals and Rare Earth Mining and Processing Supply" in Barranquilla, with Colombian President Gustavo Petro witnessing the agreement.
The framework covers rare earths, lithium, copper, and tungsten, encompassing exploration, processing, and trade activities. The agreement incorporates environmental, social, and governance (ESG) standards alongside geological survey cooperation. However, the document is characterized as non-binding, meaning it does not create legal obligations, does not grant mining rights for specific deposits, and preserves Colombia's resource sovereignty.
Any subsequent projects must undergo domestic approval within the country. According to the agreement, joint project identification and financing matching initiatives will be launched within six months of signing. The framework is part of a broader U.S. diplomatic and commercial offensive to secure critical mineral supplies amid growing concerns about geopolitical concentration risks.
China currently dominates global critical minerals production and processing. According to data from the U.S. Geological Survey and the International Energy Agency, China produced approximately 67,000 tons of tungsten out of 85,000 tons of global production in 2025, representing about 80% of world output.
In rare earth mining, China accounted for approximately 60% of global total mining in 2024. Most significantly, China controls approximately 90% of global rare earth separation and refining capacity. The concentration becomes even more pronounced in downstream processing: China's rare earth smelting products represent about 94% of the global total, while Chinese copper smelting accounts for 47% of worldwide capacity.
In 2025, China held the world's highest output in 17 mineral commodities, with 11 of these accounting for more than 50% of global production. The Colombia agreement follows a coordinated U.S. diplomatic strategy. In February 2026, Washington hosted a Critical Minerals Ministerial Meeting attended by 54 countries and the European Commission.
The U.S. signed bilateral framework agreements with 11 countries during this event. On the reserve side, the United States launched a A$12 billion "Treasury Plan" targeting 60 mineral commodities to ensure 60 days of U.S. manufacturing consumption. The U.S.
Export-Import Bank will provide $10 billion in loans from this fund. The multilateral approach has also been strengthened through upgrading the original "Mineral Security Partnership" to FORGE, which aims to promote a preferential trade zone for critical minerals and establish a price floor mechanism. Latin America has become a key focus area in this initiative, with Argentina, Peru, Ecuador, and Paraguay also signing mineral framework agreements with the United States.
Despite these developments, several risks and constraints could impede the framework's effectiveness. Political resistance has emerged within Colombia, with the country's left-wing opposition criticizing President Petro for signing the agreement without parliamentary oversight, raising concerns about potential sovereignty concessions. The funding mechanism remains uncertain: the U.S. price floor plan has been abandoned, and congressional funding is insufficient to support comprehensive development.
While the Colombian agreement mentions tools such as guarantees, loans, capital investments, and procurement agreements, the specific funding sources remain unclear. Moreover, the timeline for tangible results faces significant obstacles. The transition from framework signing to actual mine commissioning requires geological exploration, environmental impact assessment approvals, community consultations, and infrastructure construction.
The "six-month launch" mentioned in the non-binding framework refers to administrative procedures rather than capacity release, meaning substantial mining production increases are years away. For Chinese non-ferrous metal enterprises, the short-term substantive impact appears limited. However, the broader context is significant: the United States is actively promoting supply chain rule competition through its multi-faceted approach combining 54-country engagement, substantial financial resources, and preferential trade mechanisms.
Chinese industry observers emphasize the need for continuous monitoring of these developments, as the cumulative effect of U.S. diplomatic efforts and incentives could reshape global critical minerals supply networks over the medium to long term.
