In a direct challenge to China’s dominance, the United States and Japan have rolled out a concrete action plan to secure critical mineral supply chains—starting with price floors for a targeted group of minerals. This isn’t just diplomacy; it’s a strategic play to neutralize economic coercion and protect global tech manufacturing from future disruptions.
The United States and Japan on Thursday released an action plan for rare earths and critical minerals cooperation, focusing initially on price floors for a select group of minerals Reuters confirmed. The announcement came during Japanese Prime Minister Sanae Takaichi’s White House visit and aims to deliver “concrete, near-term results towards securing mutual supply chain resilience.”
This plan is the operational follow-up to the October 2025 framework agreement signed by President Donald Trump and Prime Minister Takaichi in Tokyo, when both nations were confronting the risks of Chinese export controls. That agreement was a political commitment; Thursday’s plan is the implementation blueprint, detailing specific trade and investment mechanisms.
Why focus on price floors first? The plan describes them as a border-adjusted mechanism to correct market distortions. By setting a minimum price, the approach aims to ensure producer viability even amid volatile trading conditions, directly countering tactics that could be used for economic coercion.
The plan deliberately avoids naming China but refers to “distortions resulting from pervasive non-market policies and practices” that have left supply chains vulnerable. This language targets state-led market manipulation without escalating diplomatic rhetoric.
Beyond price floors, the two countries agreed to a comprehensive strategy:
- Develop a plurilateral critical minerals supply agreement inviting other market-oriented economies to join, creating a coalition that can collectively negotiate with dominant suppliers.
- Identify and prioritize specific mining, processing, and manufacturing projects—both domestically and among allies—that meet internationally recognized responsible business practices, linking financing and policy support to ethical standards.
- Coordinate stockpiling of critical minerals to buffer against supply shocks.
- Share geological data and technical cooperation to map potential new deposits.
- Establish rapid response protocols for supply disruptions and joint actions against economic coercion.
The focus on a “select group” of minerals first allows for targeted impact. Likely priorities include those essential for defense systems (e.g., magnet materials) and clean energy transitions, though the statement did not specify which minerals will be initially designated.
What makes this plan different from past efforts? Previous initiatives often focused on single levers—like mining grants or stockpiling. This plan synchronizes trade policy, investment diplomacy, and coalition-building into a unified framework. It recognizes that no single tool can dismantle China’s processing dominance; instead, it applies pressure across multiple fronts simultaneously.
The timing is critical. China’s recent restrictions on gallium and germanium exports demonstrated its willingness to weaponize mineral access. The US-Japan plan signals that economic coercion will be met with coordinated, market-based countermeasures—a clear deterrent.
For global manufacturers, the immediate implication is potential price stabilization. By guaranteeing a floor, the plan aims to encourage investment in allied production capacity, gradually diversifying supply. However, it explicitly avoids “subsidized competition” that could trigger trade conflicts, seeking instead a predictable pricing environment.
The next phase will reveal which minerals receive priority and which nations join the plurilateral talks. If implemented effectively, this could be the first substantive crack in China’s rare earths monopoly since the 2010s, setting a template for countering economic coercion in other critical sectors.
