Chile and United States Set to Sign Agreements on Mining and Security

Reflecto News – Chile and the United States are scheduled to sign formal agreements on mining (with a focus on critical minerals) and security on Monday in Santiago, Chilean government officials confirmed.

The signing ceremony will involve senior officials from both countries, including Chilean Foreign Minister Francisco Perez Mackenna, Mining and Economy Minister Daniel Mas, and U.S. Undersecretary of State for Arms Control and International Security Thomas DiNanno.

Focus Areas of the Agreements

The pacts build on earlier cooperation frameworks and are expected to cover:

• Critical minerals and supply chain security: Strengthening bilateral ties on copper, lithium, rare earth elements, and other strategic minerals essential for the energy transition, advanced technologies, and national security. This includes exploring public and private financing for mining projects, scrap recycling, and new exploration initiatives.
• Security cooperation: Enhancing collaboration on regional stability, countering transnational threats, and broader defense-related matters.

The agreements reflect a deepening strategic partnership between Santiago and Washington, particularly under Chile’s current administration, which has prioritized attracting responsible foreign investment in its world-leading mining sector while aligning with U.S. efforts to diversify critical minerals supply chains away from dominant players.

Strategic Importance

Chile is the world’s largest producer of copper and a major lithium supplier — resources vital for electric vehicles, renewable energy infrastructure, and high-tech industries. The U.S. views reliable access to these minerals as a national security priority amid global competition for supply chains.

The mining component continues momentum from the March 2026 Joint Declaration on Critical Minerals and Rare Earth Elements, which established formal consultations between the two countries.

The security agreement is expected to address shared concerns in the region, including stability in the Southern Hemisphere and cooperation on transnational issues.

Reflecto News will provide updates from the signing ceremony in Santiago, including full details of the agreements once released, and any statements from U.S. and Chilean officials.
