China holds leverage over the incoming Trump administration through its dominance in rare-earth element production and processing. The country controls roughly 70 percent of global rare-earth refining capacity and produces about 60 percent of the world's supply, giving Beijing strategic power over industries critical to U.S. defense, technology, and clean energy sectors.

A temporary postponement of stricter Chinese export controls on rare earths expires soon, forcing negotiations at an upcoming summit. Whether China extends this pause or implements tougher restrictions will reshape supply chains for American manufacturers reliant on these materials. Rare earths power magnets in military weapons systems, electric vehicles, wind turbines, and semiconductor manufacturing. Without reliable access, U.S. defense contractors and tech companies face production constraints.

Trump administration officials have flagged rare-earth security as a priority, recognizing that dependence on Chinese supply creates vulnerability. The administration has pushed for domestic rare-earth mining and processing investments, though U.S. capacity remains minimal compared to China's industrial dominance. Building alternative supply chains requires years and billions in capital investment.

China has signaled willingness to weaponize rare-earth exports as retaliation for tariffs, technology restrictions, and trade tensions. Previous disputes saw Beijing tighten controls temporarily. If negotiations fail, Chinese export quotas could spike prices for American manufacturers and disrupt supply chains across multiple industries.

The timing pressures Trump's negotiating team. Delayed rare-earth access could stall defense production and slow the EV transition that both parties claim to support. Beijing understands this calculus and may demand concessions on trade policy, Taiwan-related restrictions, or technology licensing as the price for maintaining current export levels.

Resolution depends on whether Trump pursues confrontation or negotiation. Hard-line tariff policies could provoke Beijing to restrict rare earths, accelerating supply shocks. Pragmatic negotiations might preserve
