USTR Greer tells FT allies must accept a 'national security premium' on non-China critical minerals, risking China-retaliation pushback

Analysis
Greer's explicit framing of non-China sourcing as a national-security premium, per a single FT interview not independently corroborated, is the sharpest US push toward a closed critical-minerals bloc since the 2022 IRA minerals provisions. It very likely accelerates both allied price-floor commitments and Chinese retaliatory export controls over the coming six to twelve months. Allied concern that Beijing could replicate its November 2024 rare-earth magnet halt against France, Italy, and Japan is grounded in concrete precedent and likely materializes within the coming months if the bloc formalizes. The premium model targets Chinese-origin samarium-cobalt and yttrium inputs that CSIS flagged as load-bearing for Patriot seeker components and HIMARS rocket motors, giving the Iran war context its operational weight. The framework may instead be primarily rhetorical cover for existing DoD stockpile subsidies, in which case allies sign on nominally while continuing to optimize for Chinese pricing where politically defensible. A Japan-Korea-Australia-Canada signatory bloc is probable before year-end regardless.
