Under the terms of the deal, the two countries have agreed to use economic policy tools and coordinated investment to secure supplies of critical minerals and crack down on subsidized imports that risk undercutting domestic production.
They will jointly identify priority projects, mobilize financing for developments, and share intelligence on investments that could threaten domestic capabilities in either country.
The partnership signals a tougher stance on market distortion, with both sides pledging to protect their industries from “non-market policies and unfair trade practices” — including by working with allies on a global approach to pricing challenges.
The agreement also states both sides will use existing legislative and diplomatic tools to review, deter and potentially block critical minerals and rare earths asset sales on national security grounds.
U.S. and U.K. ministers are expected to convene within the next six months to take the partnership forward.
The Trump administration, which has announced similar agreements with Mexico, the European Union and Japan, ultimately wants to establish a critical minerals trading bloc, first floated on Wednesday by Vice President JD Vance to 54 countries.
