China Rare Earth Controls — Past, Present, and the US Counterattack

As the Iran peace deal cools the Middle East’s powder keg, another front is heating up: rare earths. In June 2026, China is expanding its controls beyond rare earths to the supply-chain chokepoints the US depends on. EV motors, missile guidance, wind turbines, the cooling and power components of AI data centers—rare earths are in nearly everything in modern industry. And China holds about 90% of the world’s refining capacity. We trace the past and present of this “quiet resource war,” and how companies are fighting to survive, through the Chief’s lens.

Why Rare Earths Became a “Strategic Weapon”

“Rare earths” denote 17 elements. Despite the name, they are not especially scarce in the crust, but mining them economically—and above all “refining and separating” them—is extremely difficult and environmentally costly. It is precisely at this refining stage that China commands about 90% of the world. Mines exist in Australia, the US, and Africa, but turning ore into usable metals and magnets effectively runs through China. This “refining bottleneck” is China’s true card.

In particular, permanent magnets (NdFeB) made from elements like neodymium and dysprosium are the heart of EV drive motors, precision-guided weapons, and wind generators. An F-35 fighter contains hundreds of kilograms; a submarine, several tons. Rare earths are not mere raw materials but the “vitamins” of advanced manufacturing and defense. Cut the supply and entire production lines halt. By aiming precisely at this point, China has made rare earths a central front of US-China competition, after tariffs and semiconductors.

China’s Control Timeline — An Increasingly Refined Blade

China’s rare-earth controls are not a single event but a strategy refined in stages. It began in April 2025, with export controls imposed in retaliation for the Trump administration’s steep tariffs. As trade tensions later partly eased, many tariffs and restrictions were lifted—but controls on key heavy rare earths were tenaciously maintained.

In October 2025, China unveiled its most comprehensive regime yet. Modeled directly on the US Foreign Direct Product Rule (FDPR), it stipulated that any product containing 0.1% or more of Chinese-origin rare earths, or made using Chinese processing technology, requires a Chinese license—wherever in the world it is produced. This was, in effect, a reverse export control projecting Chinese regulatory jurisdiction onto the entire global supply chain. In January 2026, the control list added rare-earth compounds such as samarium, gadolinium, and lutetium, and even silver.

The decisive blow came in March 2026 with State Council Order No. 834, the “Provisions on the Security of Industrial and Supply Chains”—China’s first dedicated supply-chain security framework integrating export controls, countermeasures, data security, and investment screening under one national-security mandate. Then, in June 2026, the Washington Post reported that China had begun quietly squeezing other chokepoint goods the US depends on, beyond rare earths. The “rare-earth card” has evolved into “weaponization of the supply chain at large.”

America’s Counterattack — Stockpiles, Price Floors, and State Capital

The US is not standing still. The January 2026 critical-minerals executive order declared that processed critical minerals are essential to defense, infrastructure, and advanced industry, and proposed import restrictions, investment in domestic refining and processing, and allied supply-chain cooperation. The crux is a shift to “the state intervenes directly rather than leaving it to the market.”

The most symbolic measure is the Pentagon’s direct capital injection. The Department of Defense invested about $400 million to take an equity stake in MP Materials, the largest US rare-earth firm, in a public-private partnership that also backs magnet production in Texas. It also signed a four-year, $96 million deal with Australia’s Lynas to supply light and heavy rare-earth oxides. On top of this, to shield non-China producers from Chinese price dumping, it set a “minimum purchase price (price floor)” for NdPr oxide. Even if market prices collapse, the US government buys—absorbing the uncertainty of mine investment.

Stockpiling is also underway. The Pentagon committed about $12 billion to a critical-mineral stockpile called “Project Vault” ($1.67B private capital plus a $10B Export-Import Bank loan), building “strategic reserves” to weather a supply cutoff. Japan pursues a similar strategy to insulate allied supply chains from China-driven price shocks. In short, the US-and-allies response reduces to a triad: “domestic production + stockpiling + price guarantees.”

How Companies Are Moving

At the heart of this vast realignment are non-China rare-earth firms. MP Materials, which runs the Mountain Pass mine in California and is the largest US rare-earth company, is building a magnet plant in Texas backed by the Pentagon’s equity investment. Its goal is the first US heavy-rare-earth separation capacity around 2026 and large-scale magnet production by around 2028. It is, in effect, the flagship of “US rare-earth independence.”

Lynas Rare Earths, the largest producer outside China, mines in Australia, refines in Malaysia, and is building a refining facility in Texas; its Pentagon supply deal secures stable demand. USA Rare Earth completed a 310,000-square-foot sintered-magnet “Innovation Lab” in Stillwater, Oklahoma, targeting first commercial production of 3,000 tons per year of NdFeB magnets in the first half of 2026. What these firms share is that they have become “strategic industries backstopped by the state.” Non-China mines that once collapsed in price wars with China are rising again on the safety net of government price guarantees, equity investment, and long-term contracts.

Yet reality is daunting. Raising refining and magnet know-how and scale to Chinese levels takes years, with environmental rules and huge upfront capital as obstacles. A June 2026 US-China Business Council report warned that some rare earths are already “near impossible” to obtain. US “rare-earth independence” points the right way, but a rugged road remains to actual self-reliance.

Breaking the Bottleneck — Substitution and Recycling

There are three broad paths to break China’s refining monopoly. The first is new and expanded non-China refining and magnet plants—which, as seen, demand years and enormous capital. The second is “recycling (urban mining)”: recovering rare-earth magnets from end-of-life EV motors, wind turbines, and appliances reduces reliance on fresh mining, prompting the US, Europe, and Japan to invest in recovery technology. The third is “substitution”: research into motors that use little or no rare earth (ferrite magnets, wound-rotor motors) is active, but it cannot yet fully match permanent magnets in performance and efficiency.

Ultimately, the short term cannot escape China dependence; the medium term sees non-China supply and recycling slowly fill the gap; the long term sees substitution technology change the board. This time lag is exactly China’s leverage—and the reason the US and allies are hurrying. The resource war’s outcome is a speed contest: who replicates the bottleneck first.

An Allied Resource Coalition — Is a “Minerals NATO” Possible?

The US knows it cannot solve this alone. So it is pushing a “critical-minerals alliance” binding Australia (mining/refining), Japan (technology/demand), and Canada and Europe (mines/capital). The Pentagon’s Lynas deal and price-protection coordination with Japan are the signals. Some call it a “minerals NATO”—pulling resources into the realm of a security alliance so that if one country is cut off, the allies endure together in a collective-security model.

Yet this coalition has cracks too. Who bears the environmental burden of refining plants, who shares the cost of price guarantees, and how far to risk economic ties with China—interests differ by country. Korea, a core demand nation in this coalition yet heavily dependent on China, needs a deft balancing act between “allied coordination” and “China-risk management.”

The View for Korea and Investors

Korea is a direct party to this front. Most of its mainstay industries—EVs, batteries, semiconductors, defense—depend on rare earths and permanent magnets, and that supply chain leans heavily on China. The tighter China’s controls, the more Korean manufacturing’s costs and production stability wobble. Expanding government stockpiles, localizing magnets, and diversifying supply toward Australia, the US, and Vietnam are urgent tasks.

From an investment view, rare earths carry a “geopolitical premium.” Each time China tightens, non-China rare-earth stocks swing, government funds flow in, and structural demand provides support. But volatility is high and expectations often outrun earnings, so caution is warranted. This trend moves as one body with the AI-chip and custom-chip race covered earlier and the broader US-China tech-hegemony picture. Follow the analysis at Chief Briefing. The Middle East’s fire fades while the resource-and-tech front grows hotter—the paradox of 2026 geopolitics.
