On March 19, US Trade Representative Jamieson Greer met Japanese Prime Minister Sanae Takaichi in Tokyo to sign what both governments called a turning point in critical minerals cooperation. The Critical Minerals Action Plan establishes price floors for rare earth oxides, coordinates border enforcement against subsidised Chinese exports, and commits both nations to joint research on deep-sea rare earth extraction.

TLDR

The US and Japan signed a Critical Minerals Action Plan on March 19 with price floors and joint R&D on rare earths. Australia, despite being the world's largest lithium producer and a major rare earth miner, has no defined role in the agreement. Chinese analysts see this as confirmation that Western supply chain diversification remains stuck at the extraction phase.

KEY TAKEAWAYS

01US-Japan Critical Minerals Action Plan includes unprecedented price floors at $110/kg for NdPr oxide
02Australia produces 53% of global lithium and significant rare earths but has minimal downstream processing capacity
03China controls over 60% of global rare earth processing and recently discovered 9.7 million additional tons in Sichuan
04The deal lacks timelines, funding specifics, or a defined role for Australian supply, suggesting the 'de-risking' strategy remains incomplete

Reading the agreement from Canberra, you might expect Australia to feature prominently. We produce 53% of the world's lithium. Lynas Rare Earths operates the only significant rare earth processing facility outside China in the Western alliance. Mount Weld in Western Australia holds one of the highest-grade rare earth deposits globally. Yet the Action Plan mentions Australia once, in a list of 'potential partner nations' alongside Canada and the Philippines.

Reading the same agreement from Shanghai tells a different story. Chinese financial publication Caixin ran analysis within 24 hours noting that the plan contained no processing capacity commitments, no timelines for facility construction, and no funding mechanisms. The conclusion from their trade desk: this is a pricing coordination agreement, not a supply chain restructuring.

What price floors actually signal

The $110 per kilogram floor price for neodymium-praseodymium (NdPr) oxide deserves scrutiny. This matches the revised supply agreement Lynas signed with Japanese trading houses in February, which included capped upside-sharing provisions. When NdPr prices spike above $140/kg, as they did briefly in late 2025, Lynas captures only a portion of that margin. The floor protects against downside; the cap limits participation in upside.

For Japanese manufacturers building electric vehicle motors and wind turbines, this arrangement makes industrial planning easier. They can budget for rare earth inputs at $110-140/kg and absorb the difference through other cost lines. For Australian miners, it creates a defined corridor that stabilises revenue but constrains growth during supply crunches.

The Chinese rare earth industry sees this differently. 36Kr, a technology and business publication based in Beijing, reported that domestic processors view Western price floors as an acknowledgment that non-Chinese supply cannot scale to create genuine price competition. 'If they could produce enough to move prices,' one Baotou-based processor told the publication, 'they would not need floors.'

The processing gap Beijing keeps measuring

China processes over 60% of the world's rare earths, and that figure understates the concentration in specific segments. For heavy rare earths used in high-performance magnets, Chinese facilities handle closer to 90% of global separation and metallisation. Australia mines significant volumes of rare earth ore; almost none of it becomes finished magnets or alloys on Australian soil.

Lynas operates a separation facility in Kalgoorlie and ships concentrate to its Malaysian plant for further processing. The company has announced plans for a US facility in Texas, partially funded by Pentagon contracts. But the timeline extends to 2027 at earliest, and the capacity remains small relative to Chinese output.

Meanwhile, Chinese state geologists announced a 9.7 million ton rare earth discovery in Sichuan province in January 2026. To contextualise: global rare earth production in 2025 totalled approximately 350,000 tons. The Sichuan discovery, if fully developed, represents nearly three decades of current annual production. Even accounting for grade variations and extraction challenges, this find reshapes long-term supply calculations.

Western governments keep announcing mineral security strategies. China keeps announcing mineral discoveries. At some point, strategy must convert to capacity.

This observation, posted on Weibo by a resource sector analyst with 400,000 followers, captures a sentiment I encounter frequently when reading Chinese business commentary on Western supply chain initiatives. There is genuine puzzlement at the gap between stated ambitions and built infrastructure.

What Canberra appears to be missing

Australian trade officials have spent three years discussing critical minerals with Washington, Tokyo, Seoul, and Brussels. The Quad, AUKUS, and various bilateral dialogues all include critical minerals language. Investment incentives exist. Export agreements exist. What does not exist is a single Australian facility capable of producing rare earth permanent magnets at commercial scale.

The US-Japan Action Plan includes provisions for joint research on deep-sea rare earth extraction from Pacific seabed nodules. Japan has invested heavily in this technology, with test extraction operations near Minamitorishima. The research partnership makes geographic and technical sense. But it also signals where Tokyo sees future supply originating, and it is not from Australian mines.

Lynas shares traded flat on the day of the announcement. Pilbara Minerals, focused on lithium, dropped 2.3%. The market read the agreement correctly: this deal creates pricing stability for existing supply arrangements without generating new demand for Australian processing capacity.

From Beijing, the analysis runs deeper. Export restrictions on gallium, germanium, and graphite implemented by China in 2025 demonstrated that processing concentration creates leverage. Australia can ship all the lithium and rare earth concentrate it produces; if that material flows to Chinese refineries, supply chain diversification remains theoretical. The US-Japan agreement addresses pricing. It does not address the bottleneck.

Canberra's critical minerals strategy, last updated in October 2025, emphasises upstream production and export facilitation. It mentions processing facilities as desirable without committing capital or setting capacity targets. Reading that document alongside the US-Japan Action Plan, a pattern emerges: Australia positions itself as a reliable source of raw materials while processing investment flows elsewhere.

Whether this represents a deliberate strategic choice or a coordination failure depends on whom you ask. Industry executives cite permitting delays, energy costs, and labour availability as barriers to Australian processing facilities. Government officials point to private sector investment decisions. Chinese observers, writing in Yicai and other financial publications, suggest both explanations miss the point: without state-directed capital allocation at scale, processing concentration will persist.

The US-Japan Critical Minerals Action Plan may well achieve its stated goals of price stability and research cooperation. For Australia, the question is whether those goals align with national interest, or whether we have been offered a seat at a table where the main course has already been served to others.

FREQUENTLY ASKED QUESTIONS

What is the US-Japan Critical Minerals Action Plan?
An agreement signed on March 19, 2026, establishing price floors for rare earth oxides, joint research on deep-sea extraction, border enforcement coordination against subsidised imports, and information sharing between the two nations to reduce dependence on Chinese processing.
Why isn't Australia more central to this agreement?
Australia produces raw materials but lacks significant downstream processing capacity. The agreement focuses on pricing and research rather than building new processing facilities, and Japan's deep-sea extraction research signals interest in alternative supply sources beyond Australian mines.
How dominant is China in rare earth processing?
China controls over 60% of global rare earth processing, with concentration exceeding 90% for heavy rare earths used in high-performance magnets. A January 2026 discovery of 9.7 million tons of rare earths in Sichuan further strengthens China's position.
What does the $110/kg price floor mean for Lynas?
The floor matches Lynas's revised Japanese supply agreement and provides revenue stability. However, capped upside-sharing provisions limit how much Lynas benefits when prices spike above $140/kg, trading growth potential for predictability.
