U.S. Ambassador: China Weaponizes Rare Earth Dominance, Diversifying Supply Chains Faces Criminal Risks
nashnova research
US Ambassador to China David Perdue accused Beijing of weaponizing its rare-earth dominance, saying the latest controls now classify supply-chain diversification as a criminal offense — this means the rare-earth standoff has escalated from a trade dispute into a criminal-enforcement confrontation.
What are the three phases of Beijing's rare-earth controls?
Perdue outlined three escalation steps: April 2025, China set up an export-control regime for rare earths and magnets → October 2025, the controls went global → the latest move criminalizes any effort to diversify supply chains away from China.
This means → the logic shifted from "restrict exports" to "punish workarounds" — Beijing is no longer just blocking sales but prosecuting buyers who seek alternatives.
In plain terms = it used to be "we won't sell to you"; now it's "if you try to buy elsewhere, we arrest people, seize assets, and ban travel."
What do the whistleblower mechanism and exit bans actually cover?
In June, China's commerce ministry launched a reporting mechanism encouraging tip-offs on re-routing controlled materials through third countries and illegally transferring technology under the guise of investment or R&D. Verified tipsters receive rewards. The system took effect July 1.
A rule effective September 15 goes further: authorities can impose exit bans on Chinese citizens found to have violated export controls and deemed a risk to China's industrial security.
This means → enforcement shifted from "approval-based" to "mass surveillance + personal restrictions." Individuals working in rare-earth-related businesses inside China now face direct criminal and personal exposure.
How wide is the technology-control net?
Rules published last October brought the entire rare-earth value chain under control: mining, refining, metal production, magnet manufacturing, and recycling technology are all restricted.
The critical definition: transferring technology abroad via investment, joint research, employment, or consulting all counts as an export.
In plain terms = it is not just physical materials that can't leave — even teaching a foreign party how to process rare earths qualifies as an export. The door to technical decoupling is sealed shut.
Which US rare-earth companies were directly hit?
On June 22, China's commerce ministry placed MP Materials and USA Rare Earth, along with eight other US firms, on its export-control list. MP Materials operates the Mountain Pass mine in California; USA Rare Earth is building a full mine-to-magnet domestic supply chain.
Beijing's stated reason: retaliation for the US placing Chinese firms on its "Chinese Military Companies" list.
This reflects a precision strike at the two critical nodes of US domestic rare-earth capacity — the largest existing mine and the leading end-to-end replacement project.
Why didn't the trade truce cover rare earths?
China suspended some rare-earth technology controls in November 2025, with the pause set to run through November 10, 2026.
This month the US and China agreed to extend the broader trade truce by two more months to January 10, 2027 — but Beijing has not announced a matching extension for its rare-earth-specific controls.
This means → rare earths have been carved out and left outside the broader ceasefire — this gap is the single most important signal to watch in the next round of negotiations.
