G7 Critical Minerals Meeting Confirms Acceleration of Supply Chain Diversification With China in Mind
⚡ What Happened
G7 finance ministers held a meeting on critical minerals in the United States, confirming a policy to accelerate supply chain diversification for rare earths and other materials where China holds an overwhelming market share. Reducing dependence on China is a top priority for economic security, and the G7's clear commitment to a joint approach is highly significant. Going forward, each country's ability to execute concrete investment plans and secure alternative sourcing will be put to the test.
Supply chain diversification for critical minerals is a theme the G7 has repeatedly emphasized since 2022, but as the word "accelerate" suggests, this meeting signals an intended shift from the declaratory level to the execution phase. Behind this lies the risk of certain countries tightening export controls and the structural vulnerability of China's overwhelming share in rare earth processing. While domestic legislation such as the U.S. IRA (Inflation Reduction Act) and the EU Critical Raw Materials Act is progressing, mine development takes 5 to 15 years, making short-term substitution for Chinese supply difficult. Going forward, the focus will be on partnerships with resource-rich countries such as Australia and Canada, and on concrete new mining investments in Africa and Latin America. As tensions rise between economic security and resource nationalism, the effectiveness of G7 unity will be tested.
🔍 The wording "confirmed" suggests that no substantive new agreement or breakthrough was reached. The interests of G7 member states appear aligned but are subtly divergent. The U.S. is pursuing its own subsidy-first policies through the IRA, leaving friction with the EU unresolved. Japan cannot fully sever its economic ties with China and remains cautious about excessive decoupling. The fundamental issue is that economically viable alternatives to China's processing technology and low-cost production have yet to be established. The true purpose of the meeting is likely more about signaling G7 unity externally than about concrete measures.

🔮 Next Scenarios
🎯 Incentive Map
| Player | True Incentive | Underlying Weakness | Predicted Action |
|---|---|---|---|
| Japan | Wants to demonstrate presence as a standard-bearer for economic security while maintaining delicate balance diplomacy with China and securing influence within the G7 | Deep economic interdependence with China creates a structural dilemma of being perpetually caught between a hard line on China and economic pragmatism | Prioritizes coordination within the G7 and presents "alignment on direction" rather than specific commitments as the outcome |
| China | Wants to maintain rare earth dominance as a diplomatic card and divide G7 unity. Bilateral negotiations to pick off individual countries are more advantageous | Overconfidence in resource dominance risks deepening international isolation and accelerating development of alternative technologies — a self-contradictory risk | Keeps G7 moves in check while seeking to divide members through bilateral deals. Will not hesitate to selectively tighten export controls |
| United States | Prioritizes domestic industry protection centered on the IRA while seeking to draw the G7 into its own strategy in the competition with China | "America First" policies generate conflicts of interest with allies, tending to undermine the effectiveness of multilateral cooperation | Supports the G7 framework while refusing to modify its own subsidy policies. Demands burden-sharing from allies |
⚠️ Pre-Mortem — Conditions Under Which This Prediction Fails
- Political pressure at the leaders' level during the June G7 Summit could produce an unexpectedly concrete joint investment framework
- A sudden tightening of export controls by China could dramatically heighten urgency and accelerate G7 consensus-building far faster than usual — a scenario that may be overlooked
- A bias toward "the G7 is slow to act" may lead to underestimating the progress of concrete negotiations already underway behind the scenes
HIT Condition: HIT if the G7 does not officially announce a concrete joint investment framework for critical minerals (specifying amounts, target minerals, and participating countries) by June 30, 2026
Resolution Date: 2026-06-30
