Sanae Takaichi just used her first Group of Seven summit to back Beijing into a corner, and she did it by hitting China exactly where it hurts.
For years, Western leaders have spent their summits talking in vague terms about economic coercion and de-risking. Japan’s new prime minister just skipped the pleasantries entirely. At a high-stakes working dinner in Evian, France, Takaichi caught her counterparts off guard by shifting the conversation from general geopolitical anxiety to a concrete, aggressive counter-strategy: a G7 joint stockpiling initiative for critical minerals.
This isn't just another dry diplomatic memo. It's a direct economic strike against China's chokehold on the modern supply chain.
The 90 Day Mineral Shield
China currently controls around 60% of global rare earth extraction and a massive 90% of the world's processing capacity. If you build electric vehicles, semiconductors, or defense equipment, you buy from Beijing. Takaichi knows this vulnerability intimately. Back in November, she infuriated Chinese officials by publicly stating that a conflict over Taiwan could trigger a military response from Tokyo. Beijing retaliated the best way it knew how, by slapping export curbs on critical minerals to squeeze Japanese manufacturing.
Instead of backing down, Takaichi took that scar to France and turned it into a weapon. Her proposed "Joint Stockpiling Cooperation Initiative" calls for G7 nations and like-minded allies to hold at least 90 days' worth of critical minerals.
The mechanism works simple enough. G7 members will build up shared reserves and coordinate emergency releases through the International Energy Agency if China decides to cut off supplies. Japan already operates its own robust domestic mineral reserve system. Takaichi is offering the blueprint to the rest of the alliance to build a collective shield.
Using the Persian Gulf to Prove a Point
Takaichi skillfully linked her supply chain fight to the ongoing maritime chaos in the Middle East. The summit opened right as the United States and Iran hammered out a tentative agreement to end their monthslong conflict. While Takaichi praised the diplomatic breakthrough, she used the de facto blockade of the Strait of Hormuz to drive her main point home.
The logic she presented to the dinner table was ironclad. The Hormuz crisis proved how fast a supply bottleneck can paralyze global economies. Japan relies on that single strait for roughly 90% of its crude imports, forcing Tokyo to burn through fuel subsidies and tap into domestic emergency oil reserves just to keep the lights on.
Takaichi looked at leaders like French President Emmanuel Macron and U.S. President Donald Trump and delivered a blunt warning. If a regional conflict in the Middle East can trigger that level of economic pain overnight, a coordinated mineral embargo by China would completely wreck Western industrial output.
Playing the Trump Bridge
The Evian summit is highly tense. European leaders are openly furious with Trump over aggressive trade tariffs and his skeptical approach to funding Ukraine. Because there's so much internal bickering, the G7 isn't even expected to release a traditional joint communique at the end of the week.
That friction gave Takaichi a massive opening. Dubbed Japan’s "Iron Lady," she positioned herself as the ideological bridge between Washington and Europe. She maintains excellent rapport with Trump while simultaneously signing defense pacts with European partners, like a recent joint fighter jet development deal with Italy.
By focusing the G7’s energy on economic security and supply chain resilience, Takaichi found a rare patch of common ground. Trump loves punishing China with economic leverage. Europe desperately wants to protect its domestic car and tech industries from foreign supply shocks. By focusing heavily on minerals, Takaichi managed to get the G7 leaders to agree to close coordination on China despite their massive disagreements over Ukraine and trade.
Building the New Western Fortress
Western companies can no longer afford to treat supply chain diversification as a long-term goal. The era of cheap, frictionless global trade is dead, replaced by a climate where resource access is used as an overt weapon.
If your business relies on advanced components, battery tech, or specialized electronics, you need to actively audit your tier-two and tier-three suppliers right now. Relying on components processed in China is a systemic risk that governments are preparing to isolate.
The next immediate step for international trade departments is aligning corporate procurement with the emerging G7 security framework. Watch for separate, targeted bilateral statements on mineral security coming out of France this week. Companies that proactively shift their sourcing toward friend-shoring hubs in Australia, Canada, and South America will navigate the coming regulatory and logistical choke points. Those who wait for China to pull the plug next time will find themselves completely stranded.
