Mexico Leads Pacific Alliance Push for Critical Minerals

During its 2026 pro tempore presidency of the Pacific Alliance, Mexico will prioritize the industrialization of critical minerals and rare earth elements, aiming to strengthen regional supply chains, boost high-value manufacturing, and reduce reliance on external suppliers.

Sergio Contreras, representing both the Mexican Business Council for Foreign Trade (COMECE) and the Pacific Alliance Business Council, has emphasized that these resources are no longer just commodities but essential strategic assets for regional sovereignty. By aligning the mining and processing sectors across Chile, Colombia, Mexico, Peru, and Costa Rica, the Alliance aims to build a resilient supply chain for semiconductors and advanced batteries, effectively reducing dependence on extra-regional suppliers and fostering high-value manufacturing within the bloc.

To support this industrial push, the Mexican presidency is championing a comprehensive regional platform for the circular economy. This initiative seeks to harmonize ESG standards and material efficiency protocols, ensuring that the bloc remains competitive in a global market that increasingly demands transparency and sustainability. By creating a unified framework for resource traceability, the Alliance intends to attract high-quality foreign investment and facilitate smoother entry into international markets that prioritize green production criteria.

The 2026 agenda also places a heavy emphasis on digital transformation and financial integration. Recognizing that SMEs are the backbone of regional trade, the council is promoting cybersecurity standards to shield digital commerce from operational risks. 

Furthermore, a renewed dialogue with finance ministers is underway to integrate regional capital markets, which would lower the cost of financing for large-scale infrastructure and mining projects. These efforts are designed to ensure that the Alliance, which already represents 40% of Latin America's GDP and nearly 60% of its total trade, can operate with the necessary scale and financial depth to compete as a unified economic bloc on the world stage.

The expansion of the alliance remains a core diplomatic priority under Mexico’s leadership, with the continued promotion of Costa Rica as a full member and Singapore as an associate state. Costa Rica brings specialized knowledge in high-tech and environmental sectors, while Singapore serves as a critical bridge to Asian markets and advanced manufacturing standards. This expansion, combined with a push for regulatory harmonization, aims to minimize administrative friction and solidify the Pacific Alliance as a premier destination for strategic global investment.

US Builds Global Alliance to Counter China’s Minerals Dominance

This Pacific Alliance push aligns with a broader global effort to secure critical mineral supply chains and counter mineral dominance.

In early 2026, the United States escalated its efforts to dismantle China’s monopoly on critical minerals. This strategy has shifted from market competition to a proactive, alliance-based intervention designed to insulate allied industries from predatory pricing and supply shocks. 

The cornerstone of this effort was the Inaugural Critical Minerals Ministerial on Feb. 4, 2026, which brought together 55 nations to formalize a preferential trade zone for strategic materials. The initiative will explore measures such as price supports, standards, subsidies, and guaranteed offtake to stimulate production, with Mexico among the participating countries.

US officials warned of the risks of concentrating mineral production in China, highlighting vulnerabilities from geopolitical pressure, supply shocks, and political or health crises. US Secretary of State Marco Rubio also raised concerns that government-backed subsidies and other market distortions have undermined competitiveness and discouraged new projects outside dominant suppliers. Vice President JD Vance added that Washington seeks to prevent low-cost mineral inflows from weakening domestic and allied industries. Under the plan, benchmark prices would be set at multiple stages of the value chain, supported by variable tariffs to maintain minimum pricing levels for members of the preferential group.

Domestically, the SECURE Minerals Act of 2026 provided the legal and financial backbone for these global efforts. The legislation authorized US$2.5 billion to establish the Strategic Resilience Reserve (SRR), a government-run corporation designed to stabilize markets through the strategic stockpiling of recycled and allied-sourced minerals. 

Among other global efforts to diversify mineral supply chains, a renewed dialogue between Presidents Trump and Lula da Silva has been driven largely by rare earth interests. Brazil holds the world’s second-largest rare earth reserves, estimated at 21 million tons, but the sector has long faced capital constraints. To unlock this potential, the US International Development Finance Corporation (DFC) provided nearly US$500 million in financing to Serra Verde, Brazil’s only active rare earth producer. The partnership aims to leverage Brazil’s vast deposits to strengthen the Western Hemisphere’s defense and technological capabilities. The establishment of Brazil’s National Mining Policy Council in late 2025 further signals a commitment to streamline regulations and position the country as a reliable alternative to Chinese supply chains.

China’s Dominance in Critical Minerals and Strategic Risks

Critical minerals underpin energy technologies, advanced manufacturing, defense, and high-tech industries, yet global supply chains remain heavily reliant on China, creating strategic vulnerabilities. 

The IEA’s Global Critical Minerals Outlook 2025 shows China dominates refining for 19 of 20 key minerals, holding roughly 70% of the market, and controls 91% of rare earth refining and 94% of permanent magnet production. Export restrictions imposed in 2025 on rare earths and related products have already caused shortages, price spikes, and risks for sectors from defense to AI and semiconductors.  China also dominates lithium-ion battery midstream and downstream production, including cathodes, anodes, and cells, threatening electric vehicle and energy storage supply chains. Diversifying sources is slow: projects outside China face long lead times, limited scale, and insufficient midstream capacity.
