China Found Something Better Than Oil
A detailed account of how China methodically built, weaponized, and finally revealed a stranglehold over the rare earth minerals that steer every missile in the American arsenal.

The first rule of being a monopoly is you do not talk about being a monopoly — and China crossed that line on April 4th, 2025.
AI Summary
Maxinomics explains why rare earth magnets—not rare earths in general—are the true strategic chokepoint in the modern economy and military. Permanent magnets made from rare earth metals like neodymium power everything from AirPods and electric cars to the steering fins of cruise missiles, and one country, China, controls 94% of magnet rare earth production.

Two Chinese companies that owned 62% of buyer Sexton were controlled by sons-in-law of Deng Xiaoping when they acquired magnet patent-holder Magna Quench from GM in 1995.
Mountain Pass's pipeline ruptured more than 60 times over 12 years, spilling almost a million gallons of toxic, radioactive water, effectively ending U.S. rare earth refining.

China broke the unwritten rule monopolists follow by openly declaring its power on April 4th, 2025.
In context
The West got clean industry, and accepting that trade off meant losing some manufacturing and becoming dependent for a critical material. It was plausible. Felt like a clean trade. Both parties win some, both parties lose some. Everyone aware that, yes, China could deliver some pain if they wanted to. But the first rule of being a monopoly is you do not talk about being a monopoly. Do not publicly admit you are a monopoly in words or in actions. De beers monopoly. Luxottica, the company that makes 95% of all glasses. Sun and regular monopoly ASML, the company

China didn't build its monopoly because it's the only country with rare earths. It built it by doing the thing no one else wanted to do: separating them from the dirt.
China's dominance came from mastering an unwanted, dirty industrial process, not from geology.
In context
They did move by move, pulling the entire industry into their control. But how they managed to do this over the course of two decades is only one half of a very interesting story. The other half? Did you know rare earths aren't actually rare? China did not build its monopoly because it's the only one that has these rare earths. China built its monopoly by doing the thing no one else wanted to. Separating them from the dirt and rocks there founded. Every circle on this map is a rare earth deposit, a place where we know that mixing

The foreign company actually paid to hand them over — all the hard-won know-how that used to live inside a company in Detroit or Tokyo walked into a factory in China.
Western firms unknowingly funded the transfer of their own manufacturing expertise to China.
In context
Foreign companies still need these finished parts. They just can't pull the half finished metal out of China the way they used to. So they hire a Chinese plant to make the magnet. They hand over the drawings, the quantities, the exact recipe, all the hard one. Know how that used to live inside a company in Detroit or Tokyo walks into a factory in China. They didn't buy the secrets the foreign company actually paid to hand them over. Think about an iPhone. Roughly $9 of raw materials. The finished phone sells for something

China has not a 94% monopoly on samarium, but a 99% monopoly — and when it fully banned exports, it quoted its "consistent stance on upholding world peace."
China's near-total samarium monopoly and its ironic peace rhetoric reveal the calculated cynicism behind the export ban.
In context
more steps, costing 12 times more to refine than neodymium, and found in fewer places in the ground. When China fully banned exports of samarium in response to tariffs being put up, they knew exactly how it was being used. And I quote this reflects China's consistent stance on upholding world peace and regional stability. You would not ban this stuff and then mention peace if it was a military thing to which a lot of people around the world answered, this is unacceptable. I think it's time for a Manhattan Project like effort to end our rare

Publicly revealing your monopoly has zero long-term upside. It's usually reserved for when war is breaking out.
Breaking monopoly silence is a last-resort signal, historically associated with the threshold of war.

their control, they could take it away if they wanted to, that it was definitely not organic. It was planned control of all the trade moves between the US and China over the past decade. The rare earths one was the most extreme because publicly revealing your monopoly has zero long term upside. It's usually reserved for when war is breaking out, because you want to play the card as a last resort only when it really matters. Otherwise, you will encourage everyone to immediately start solving the problem, which is exactly what
