US-Thailand Memorandum of Understanding on Cooperation to Diversify Global Critical Minerals Supply Chains

Mechanism

The 26 October 2025 Kuala Lumpur signing produced a paired instrument set similar to (but lighter than) the US-Malaysia package signed the same day:

• Critical Minerals MoU. Non-binding cooperation framework.

Establishes regular working-level meetings between USTR / Commerce / State and Thailand's Ministry of Commerce and Ministry of Industry. Cooperation areas: exploration, extraction, processing, refining, manufacturing, recycling and recovery, technology transfer, and capacity building. Explicitly disclaims legal-binding effect under international law and creates no automatic funding obligation. Either party may discontinue cooperation with written notice.

• Framework for an Agreement on Reciprocal Trade (ART). A

framework — not a signed binding ART — covering the eventual treaty terms. Under the framework, Thailand commits to eliminate tariff barriers on approximately 99% of goods (industrial, food, agricultural), accept US-manufactured vehicles built to US federal motor-vehicle standards, and recognise US FDA certificates for medical devices and pharmaceuticals. The US commits to maintain (rather than raise) its 19% reciprocal-tariff rate on Thai imports under EO 14257, with carve-outs for designated products. The binding ART itself is to be negotiated, signed, and ratified in subsequent weeks.

Critical-minerals provisions in the MoU

The Thailand MoU lacks the Lynas-style processing-anchor that gives the parallel Malaysia agreement its strategic punch (Thailand has no operating REE separation plant and is not a top-10 rare-earth producer). Instead, the substantive content is forward-looking:

1. Exploration and extraction cooperation — likely targeting Thailand's tin, tungsten, antimony, and tantalum reserves plus prospective rare-earth deposits in the Doi Inthanon and Phang Nga regions. 2. Processing and refining — positioning Thailand as a downstream value-addition hub for regional ore feedstock, leveraging existing electronics-assembly infrastructure (Thailand is the second-largest hard-disk-drive manufacturer globally and hosts Western Digital, Seagate, and major automotive/EV component supply chains). 3. Recycling and recovery — explicit MoU coverage of end-of-life recovery of REEs, lithium, and battery metals from electronic waste. 4. Investment-screening cooperation — good-faith commitment to develop national-security review authorities for critical-minerals asset transactions. This is the forward-looking China-acquirer hook.

Why pair MoU + ART framework

Same architectural pattern as US-Malaysia (signed same day) and US-Japan (signed 27 October 2025): the MoU provides the procedural-cooperation bureaucratic surface area; the ART locks in the tariff schedule and, where applicable, mineral non-restriction commitments. The Thailand variant is a shallower instance because (a) the ART is still at framework stage rather than fully negotiated, and (b) Thailand lacks the processing-anchor leverage Malaysia has via Lynas Kuantan.

Downstream implications

• ASEAN bilateral wave. This is one of four agreements in

the same KL signing week (Cambodia, Malaysia, Thailand, Vietnam), constituting the most intense bilateral trade-architecture push of the second Trump administration to date. Reads as the ASEAN-side complement to the US-Japan framework (27 Oct) and the earlier US-Korea STIDA (4 Dec).

• Counter-architecture to China REE export controls. Reads

directly against the 2025-04-04 heavy-REE licensing and 2025-10-09 extraterritorial REE controls — Thailand becomes another sanctioned non-China processing/recycling node for US buyers, even if absolute volumes will be small relative to Lynas-Malaysia or DOD-funded US domestic capacity.

• Tariff floor at 19%. Mirrors the Malaysia structure:

Thailand's pre-Liberation-Day MFN tariff into the US averaged ~3-5%; the framework converts the emergency-authority 19% into an eventual treaty-locked baseline. Materially compressive for Thailand's HDD, automotive components, and processed-food exporters.

• Investment-screening hook. The good-faith commitment on

national-security review of critical-minerals asset sales signals that Thailand will be asked to refuse Chinese-origin acquirers of any new processing capacity built under the MoU — extending the de-facto "no China" perimeter that the US has imposed via IRA FEOC rules and CHIPS Act guardrails.

• FORGE-track precedent. The Thailand MoU fits the broader

FORGE bilateral critical-minerals umbrella launched 4 February 2026 (2026-02-04-us-state-forge-critical-minerals-launch), alongside Malaysia, Uzbekistan, Mexico, and others.

Open questions

• Timeline for the binding US-Thailand ART itself — the framework

notes negotiations will continue "in the coming weeks" but no signing date is committed; track USTR and Federal Register for any subsequent signed-ART announcement.

• Whether Thailand will codify any specific REE/critical-mineral

export non-restriction commitments in the eventual ART (the Malaysia ART includes binding language on this; the Thailand framework does not yet).

• Whether the 19% reciprocal rate survives the V.O.S. Selections

IEEPA litigation (rate is grounded in EO 14257 authority).

• How the Thai MoU interacts with Thailand's National

Semiconductor Strategy (announced 7 Jan 2026) — the back-end-assembly capacity that strategy aims to scale will be a downstream beneficiary of any minerals-processing build-out under the MoU.
