China has a powerful card to play in its fight against Trump’s trade war

Hong Kong (CNN) — Less than a year into Donald Trump’s first trade war with China, Chinese leader Xi Jinping made a high-profile visit to an unassuming factory in Ganzhou, an industrial city nestled among rolling hills in the country’s southeast.

Touring its exhibition hall in 2019, Xi examined row upon row of unremarkable grey metal blocks and declared to his entourage of Communist Party officials: “Rare earths are a vital strategic resource.”

Nearly six years on, China’s dominance of the rare earths supply chain has emerged as among its most potent tools in a renewed trade war with the United States president. The minerals – used to power everything from iPhones to electric vehicles – are vital components for the kinds of advanced technology that will define the future.

And unlike tariffs, it’s a front where Trump has little room to retaliate in kind.

Rare earths are a group of 17 elements that are more abundant than gold and can be found in many countries, including the United States. But they’re difficult, costly and environmentally polluting to extract and process.

For decades, the US and other countries have been dependent on Beijing’s supply of these processed metals. China accounts for 61% of global mined rare earth production, but its control over the processing stage is 92% of the global output, according to the International Energy Agency.

On April 4, after years of veiled warnings, the Chinese government placed export restrictions on seven types of rare earth minerals, as part of its retaliation against Trump’s initial 34% “reciprocal” tariffs on Chinese goods. The new rules require all companies to secure government permission to export the seven minerals as well as associated products, such as magnets.

Magnets made of rare earths enable smaller, more efficient motors and generators used in smartphones, car and jet engines, and MRI machines. They are also essential components in a range of big-ticket weapons, from F-35 stealth fighter jets to nuclear-powered attack submarines.

“It’s China showing that it can exert incredible economic might by being strategic … and surgical and really hitting American industry right where it hurts,” said Justin Wolfers, a professor of economics and public policy at the University of Michigan.

On Tuesday, Trump ordered a probe into potential tariffs on critical minerals, a broader category of resources that include rare earth elements, to evaluate the impact of these imports on America’s security and resilience.

“The dependence of the United States on imports and the vulnerability of our supply chains raises the potential for risks to national security, defense readiness, price stability, and economic prosperity and resilience,” Trump said in an executive order.

Since the first Trump administration, the US has been trying to play catch-up and build up its own domestic rare earths supply chain. Three American rare earth industry companies told CNN that they are in the process of expanding production capacities and sourcing materials from US allies and partners.

But those efforts will take years to meet the enormous demand from key US industries.

Suspended orders

For now, the impact of Beijing’s export controls is being swiftly felt on the ground.

John Ormerod, founder of rare earth magnet consultancy JOC, told CNN that shipments of rare earth magnets belonging to at least five American and European companies have been halted in China since the imposition of the order.

“They were taken by surprise so there’s a lot of confusion on their side and they needed clarification from the authorities of what’s required (to obtain the required export licenses),” he said.

Joshua Ballard, CEO of USA Rare Earth, said the export controls focus on “heavy” rare earths, which are 98% controlled by China. (Heavy rare earths are less common, harder to process and more valuable.) This means that companies must now seek Beijing’s approval to deliver these critical materials to key American industries, he added.

“Right now, literally these exports are being suspended,” Ballard said. “We don’t hold a lot of back stock of this in inventory here in the US … This is China’s best play. They don’t have much leverage when it comes to tariffs on us, but they sure do have leverage here.”

The export controls not only target single materials but also alloys and products where the elements are contained even in minimal quantities, said Thomas Kruemmer, director of the Singapore-based mineral and metal supply chain firm Ginger International Trade and Investment. “A lot of exports now fall under this licensing system,” he added, noting that some delays are expected as exporters navigate the new system.

Decades in the making

China got an early start in rare earth extraction, beginning in the 1950s, according to state media, but the industry only really began to develop in the late 1970s.

During that time, China combined its low labor costs and relatively lax environmental standards with the adoption of foreign technologies, according to Stan Trout, founder of the rare earths and magnetic materials consultancy Spontaneous Materials.

“Much of the technology that they brought in was developed here in the US, or in Japan, or in Europe,” he said. “And over time, I’m sure they’ve made improvements to it.”

As the country’s rare earth production increased, Beijing gradually understood the strategic importance of the minerals. “There was a recognition that this could be a very important technology for them to master,” Trout added.

In 1992, during a visit to one of the country’s main rare earth production hubs in Inner Mongolia, Deng Xiaoping, the former Chinese leader who spearheaded the country’s economic reforms, famously said: “While there is oil in the Middle East, China has rare earths.” Today, China has fulfilled Deng’s vision by dominating the entire supply chain for the materials.

While labor costs are now higher, China’s control of the industry has been cemented because of its “willingness to invest in the technology, the R&D, and automation” in an industry that is highly capital-intensive, said Ormerod.

There were once American companies making these rare earth magnets. But Ormerod noted that they gradually exited the business as lower-cost Chinese alternatives emerged.

“We’ve lost the know-how, we’ve lost the human resource capability and it’s a very capital-intensive operation,” he said.

Now, it is difficult to compete with the “Chinese price,” because of the country’s greater economies of scale, as well as government incentives that gave them an additional edge, Ormerod added.

Between 2020 and 2023, the US relied on China for 70% of its imports of all rare earth compounds and metals, according to a US Geological Survey report this year.

Challenge and opportunity for the US

The latest export controls are not the first time Beijing has leveraged its dominance in the industry. In 2010, China halted shipments of rare earths to Japan for nearly two months over a territorial dispute. In late 2023, Beijing imposed a ban on rare earth extraction and separation technologies.

Beijing has also curbed exports of other critical minerals that are vital to the economy and global supply chains.

Experts and industry insiders said China’s export controls have left the rest of the world with very limited alternatives. But the US is working to fill the gap.

Since 2020, the US Department of Defense has awarded more than $439 million to establish domestic rare earth element supply chains. And it has set a goal to develop a sustainable, mine-to-magnet supply chain capable of supporting all US defense requirements by 2027.

Some American companies see China’s export controls as an opportunity to expedite domestic production and push for a stronger supply chain outside China.

Nicholas Myers, CEO of Phoenix Tailings, a Massachusetts-based rare earth processing start-up, said his company has developed technology to refine rare earth minerals with “zero waste, zero emissions” into metals and metal alloys, sourcing the materials from domestic ores as well as Canada and Australia.

His company currently produces 40 metric tons of rare earth metals and alloys per year and aims to scale up to 400 tons with a new facility in New Hampshire.

“It’s all domestic processing. We don’t rely on anything from China,” he said.

“The United States absolutely has the capabilities to be able to produce the rare earth metals at the timelines that we really need it. We just have to make sure that all the customers, all the policymakers are focused on supporting the industry to really scale up,” Myers added.

American businesses are making inroads in parts of the supply chain too.

USA Rare Earth is building a magnet plant in Texas, aiming to produce 5,000 tons of rare earth magnets annually; it also owns a deposit rich in heavy rare earths in West Texas, including all the minerals on China’s latest export control list, according to its CEO Ballard. (The deposit is also rich in gallium, a critical material banned by China for export to the US in December.)

But the company is still working on the processing technology to extract minerals from the rocks, Ballard said.

“The question is how do we do this faster? How do we unlock these assets that we have in the US, as few as they are? We need to unlock what we have and build as quickly as we can,” he said.

After years of talk, American companies may finally have the impetus they need to do the difficult work of re-establishing the industry for extracting and processing raw materials that is key to winning a tech race with China.
