China's Rare Earth Export Controls Escalate Trade Tensions with U.S.

China has expanded its export controls on rare earth elements, a move that has intensified trade tensions with the United States and sent shockwaves through global supply chains. The Ministry of Commerce announced on October 9, 2025, that the new restrictions would take immediate effect, targeting not only raw materials but also processing technologies and components critical to advanced technology and defense industries.

The new regulations require export licenses for technologies related to rare earth mining, smelting, separation, metal smelting, magnetic material manufacturing, and recycling. Notably, applications related to advanced semiconductors, specifically 14-nanometer chips or more advanced, will be approved on a case-by-case basis. The Ministry of Commerce stated that these measures are essential for "better safeguarding national security and interests" and preventing the transfer of critical items for military or sensitive applications by "overseas bodies and individuals."

In response, President Donald Trump threatened to restore tariffs on China to triple-digit levels due to Beijing's new controls, prompting the Chinese government to vow "corresponding measures." This escalation has rattled markets, unnerved global industries, and rekindled fears of a repeat of the tit-for-tat tariff offenses earlier this year.

The rare earth elements affected by China's export controls are crucial for various defense technologies, including fighter jets, submarines, missiles, radar systems, and unmanned aerial vehicles. The United States, which relies heavily on Chinese-processed rare earths, faces significant challenges in maintaining its defense industrial base amid these restrictions.

China's dominance in the rare earth sector, accounting for approximately 70% of rare earth mining, 90% of separation and processing, and 93% of magnet manufacturing, gives it significant leverage in global supply chains. The new export controls are seen as a strategic move to reinforce this position and counter Western restrictions on high-tech exports to China.

The escalating trade tensions and China's tightening grip on rare earth exports have prompted concerns about the stability of global supply chains and the potential for further disruptions in industries ranging from technology to defense.
