Japan Pushes G7 Price Floors and Stockpiling to Counter China’s Rare-Earth Export Controls

G7 Initiative and Japan’s Proposal for Critical-Mineral Price Floors
At the G7 summit in Évian-les-Bains on 16 June 2026, Prime Minister Sanae Takaichi announced a “joint stockpiling cooperation initiative” and urged the group to adopt mineral-specific price-floor guarantees. The plan targets rare earths and permanent magnets, citing a reference floor of US $110 per kg for neodymium and praseodymium, and calls for coordinated stockpiles to keep the share of non-G7 suppliers below 60 % by 2030.
Historical Context of China-Japan Rare-Earth Tensions
China halted rare-earth exports to Japan in 2010 after a maritime incident and again in January 2026, citing Japan’s “remilitarization.” A WTO ruling in August 2014 found China’s export controls inconsistent with trade rules, but Japan had already lost a large share of its supply. By 2020 Japan reduced China’s share of rare-earth imports from roughly 90 % to about 60 %.
Principal Actors and Partnerships
- Sanae Takaichi – Japanese Prime Minister.
- Lin Jian – Spokesman, Chinese Foreign Ministry.
- Lim – Chinese commentator.
- Shin-Etsu Chemical – Building a domestic refinery in Fukui (¥35 bn, half subsidised).
- JOGMEC – Joint venture JARE with Sojitz, partner of Lynas Rare Earths (US $250 m stake).
- Aclara Resources – Canada-based miner with projects in Brazil and Chile.
- JX Advanced Metals and Marubeni Corp – Stakes in Australian and New South Wales mineral projects.
- International bodies: International Energy Agency, World Bank Group’s RISE Partnership, Asian Development Bank, Inter-American Development Bank.
Quantitative Landscape
- 2010: Japan imported ?28,000 t of rare earths, ?90 % from China.
- 2020: China’s share fell to ?60 %.
- US $250 m investment in Lynas; US $110 /kg floor for 5,000 t of neodymium/praseodymium.
- 7,200 t of neodymium/praseodymium deliveries secured through 2038.
- Brazil’s rare-earth reserves: ?21 million t (second only to China).
- Aclara’s projected output: 15 % of China’s 2024 production; heavy-rare-earth output 150 kg yr?¹.
Official Statements & Responses
Takaichi warned that China’s export restrictions could “severely impact” G7 supply chains and urged cooperation with multilateral development banks. The G7 communiqué endorsed coordinated stockpiling and the price-floor framework. China’s foreign ministry asserted the bans “aim to contain Japan’s remilitarization” and maintain “global critical-mineral supply-chain stability.” Benjamin Lin of Taiwan’s TECO noted that mineral-specific price floors could become a standard counter-measure to non-market pricing.
Criticism & Opposition
Chinese officials and analysts argue Japan’s approach “fails to secure dialogue” and “stokes confrontation.” Lim described Japan’s attempts to rally allies as “obtrusive” and destined to fail. The “Sea Lion” columnist highlighted that domestic rare-earth prices in Japan “tripled” after the January ban and dismissed Aclara’s Brazil-Chile projects as economically unviable.
Divergent Accounts and Uncertainties
Chinese statements portray the export controls as stabilising, while Japanese officials present them as disruptive. No independent data confirm the effectiveness of the proposed price-floor mechanism, and timelines for deep-sea extraction remain speculative. The impact of Japan’s domestic refinery and Brazil partnerships on overall supply shares is not yet quantified.
Verbatim Quotes
- “In accordance with laws and regulations, China has banned the export of all dual-use items to Japanese military users and for Japan’s military use,” — Lin Jian, Foreign Ministry spokesman
- “I want to discuss urgent issues frankly with other leaders and demonstrate the G7’s unity in leading the international community’s response to the issues,” — Sanae Takaichi, Prime Minister of Japan
- “After China cut off rare earth supplies to Japanese military-linked entities in January, domestic prices in Japan tripled,” — Sea Lion, Hefei-based columnist
- “Its leader’s latest G7 remarks on China were particularly obtrusive, exposing that its attempt to rally allies and stir up confrontation wins no support and is bound to fail.” — Lim, Chinese commentator
- “Calling for dialogue with one hand while busy stoking confrontation with the other is utterly self-contradictory, and has enabled the international community to see through Japan’s hypocrisy ever more clearly,” — Lin, Global Times
Prospects and Upcoming Steps
Japan will send a delegation to Greenland to evaluate rare-earth extraction and continues deep-sea sediment sampling at 6,000 m depth. The G7 aims to finalize the price-floor framework and expand stockpiling before the 2030 target. The success of these measures will determine whether critical-mineral pricing shifts toward a more diversified global market.
