US Secretary of State Marco Rubio and EU Trade Commissioner Maros Šefčovič signed a memorandum of understanding on critical mineral cooperation.
The MoU aims to diversify supply chains and reduce reliance on China-dominated rare earth and critical mineral sources.
Rubio emphasized that concentration of these resources in one or two places poses an unacceptable risk to economic security.
The agreement reflects growing awareness among Western allies of the strategic importance of critical mineral supply chains.
