FCDO signs Memorandum of Understanding with US on critical minerals supply chains
The Foreign, Commonwealth & Development Office (FCDO) has signed a Memorandum of Understanding with the United States on critical minerals supply chain security, executed in Washington DC on 4 February 2026. The agreement establishes cooperative commitments to accelerate secure supply of critical minerals and rare earths necessary for defence and advanced technology manufacturing. Key provisions include joint identification of critical mineral projects, coordinated government financing support, streamlined permitting processes within domestic regulatory systems, and establishment of a Mining, Minerals and Metals Investment Ministerial within 180 days. The participants commit to using existing legislative and diplomatic tools to review and restrict critical minerals asset sales on national security grounds, while supporting recycling technology and geological mapping cooperation. The MoU explicitly states it does not create legally binding obligations under domestic or international law and either party may discontinue participation with 30 days' written notice. This agreement supplements the UK's Critical Minerals Strategy published in November 2025, which was backed by £50m funding, and adds to existing bilateral agreements with Australia and Canada.
