• Mexican President Claudia Sheinbaum denies signing any binding agreement on critical minerals with the U.S., emphasizing sovereignty.
  • The U.S.-Mexico Action Plan announced February 4, 2026, is a non-binding 60-day framework for discussions on supply chain coordination.
  • Talks aim to integrate outcomes into the USMCA Joint Review by July 1, 2026, amid global efforts to reduce reliance on China.

A Framework, Not a Deal

Mexican President Claudia Sheinbaum has clarified that no formal deal on critical minerals was signed with the United States, putting to rest speculation following the announcement of a U.S.-Mexico Action Plan earlier this month. The one-page document, unveiled at the 2026 Critical Minerals Ministerial in Washington, D.C., is instead a non-binding 60-day framework for discussions, according to people familiar with the matter. Sheinbaum's statement, issued through official channels, stresses that this aligns with Mexico's focus on sovereignty as USMCA negotiations continue.

"There is no binding agreement at this time," a senior Mexican official said, requesting anonymity due to the sensitivity of ongoing talks. "What we have is a roadmap for dialogue, not a finalized pact." The Action Plan outlines potential coordination on identifying critical minerals like lithium, copper, silver, and cobalt—key for electric vehicles, electronics, and renewable energy—as well as exploring border-adjusted price floors to counter dumping, regulatory standards, geological mapping, joint stockpiling, and investment screening. Efforts to integrate these elements into the USMCA Joint Review by July 1, 2026 have hit a snag, with both sides cautious about overcommitting.

Economic and Political Stakes

Critical minerals are increasingly seen as vital for securing supply chains amid 2025 trade war disruptions, such as China's rare-earth export restrictions. Mexico, a major producer of silver and copper, faces challenges with frozen mining concessions since 2018 and declining exploration investment, which dropped from $543 million in 2023 to around $400 million in 2025. Without a thaw in private investment, the country risks stalled development despite its geological potential, industry analysts warn. The Action Plan fits into broader USMCA review preparations, framed by U.S. officials like Vice President JD Vance as a "technology sovereignty play" to build allied trading blocs.

Marcelo Ebrard, Mexico's Economy Minister, has prioritized minerals as a national security issue, but Sheinbaum's administration maintains a cautious stance. "We are committed to constitutionality and protecting our resources," Ebrard said in a brief statement, though he did not elaborate on specifics. Critics, including the group Cambiemosla Ya, have called the framework a sovereignty risk, arguing it betrays anti-privatization promises. Meanwhile, stakeholders like CAMIMEX, a mining industry group, warn of decade-low investment levels, while U.S. firms such as Boeing eye potential stockpiling opportunities.

Looking Ahead

The 60-day window, set to conclude by early April 2026, will focus on drafting mineral lists and price mechanisms. If successful, these could be embedded into USMCA or lead to standalone agreements, but regulatory hurdles loom—new mines can take up to 18 years to become operational. In the short term, the framework's fate hinges on whether Mexico resumes lithium exploration budgets, which have seen only modest increases under Sheinbaum. Long-term, experts predict that North American supply chain resilience could benefit, but Mexico's mining moratorium risks "nearshoring disappointment" if not addressed.
