The United States and the European Union have signed a memorandum of understanding to diversify critical mineral supply chains. The agreement focuses on mining, processing and refining activities. Critical minerals are essential for energy technologies, including batteries and wind turbines, and supply disruptions from the Middle East have prompted a search for alternative sources. The article does not disclose specific figures or timelines for the implementation of the agreement. The MOU is expected to encourage collaboration between U.S. and EU firms and governments, potentially accelerating the development of domestic and allied critical mineral projects and reducing exposure to geopolitical risks.
