A U.S. business group reported on June 10, 2026, that some critical minerals subject to China's export controls are now "nearly unobtainable" — a finding that cuts through months of diplomatic negotiation and shows where the supply chain actually stands.

The sequence of events began in April 2025, when China introduced export licensing requirements for medium and heavy rare earth elements. This was a direct retaliation for tariff increases the Trump administration had announced. Rare earths are metals embedded in nearly everything electronic: fighter jets, electric vehicle motors, semiconductor chips. China controls roughly 90 percent of the world's refining capacity for these materials — processing ore into usable form — even though mining happens in Australia, the U.S., and other countries. That processing bottleneck is what makes the controls effective.

What followed was a pattern of escalation, pause, and partial reversal that left manufacturers unable to plan. In October 2025, Beijing expanded the licensing rules to cover any company anywhere in the world whose products contained rare earths above a certain level. The Chinese government said these were licensing requirements, not outright export bans — technically, licenses could be granted. In practice, the bottleneck achieved similar effect.

Then the suspensions began. Beijing paused its extra restrictions on certain materials like gallium. In April 2026, it temporarily halted the October controls entirely until November 10, 2026. After a Trump-Xi summit in May, China rolled back some restrictions — but left the original April 2025 licensing system in place. On May 18, the White House announced that China had agreed to address U.S. concerns. Two days later, China's Ministry of Commerce said it would cooperate on "reasonable" concerns while reaffirming that the controls themselves were lawful.

That word — "reasonable" — is handling a lot of diplomatic weight. The April 2025 core regime remains active. Suspensions of later restrictions only buy time; they don't solve the underlying problem. A company sourcing dysprosium or terbium cannot build a procurement strategy around controls that expire on a calendar date.

The situation reflects a structural reality that diplomacy alone cannot quickly change. China's dominance in rare earth processing means these licensing controls work as leverage. Mining has diversified — Australia and the U.S. now produce ore — but refining and separation capacity outside China remains underdeveloped. Building new refineries takes years and billions of dollars.

On the diplomatic side, there has been activity. The State Department hosted a Critical Minerals Ministerial in February 2026, framing rare earths as essential to AI, advanced robotics, and defense systems. The G-7 committed to faster supply diversification. In March, the State Department identified Africa as a priority for accessing cobalt, copper, graphite, and rare earths. These are medium-to-long-term strategies. The licensing constraint is immediate.

Industry forecasts bear this out. S&P Global warned in January 2026 that rare earth bottlenecks would persist through the year, with prices rising for affected elements. The June business-group report confirms that prediction. For defense manufacturers, EV producers, and semiconductor fabricators relying on these materials, the gap between what diplomats have announced and what production lines actually need is now measurable in lost output.

What exists now resembles a managed holding pattern. Beijing has shown it will suspend the broadest restrictions and engage in talks, while keeping the legal framework of the April 2025 regime intact. Washington secured verbal commitments but not a full dismantling of the controls. The November 2026 suspension expiry dates mark the next decision point. How both governments handle that window — especially whatever the tariff environment looks like then — will determine whether this partial truce survives or the controls come back in force.
