US-Armenia Minerals Deal Puts Yerevan at the Centre of Great-Power Competition

The deal in Yerevan

On 26 May 2026, US Secretary of State Marco Rubio and Armenian Foreign Minister Ararat Mirzoyan signed a memorandum of understanding on critical minerals and rare earth metals in Yerevan, accompanied by a broader strategic cooperation agreement covering multiple sectors. The signing took place during a visit that represented one of the most direct high-level engagements between Washington and Yerevan in recent memory. The Armenian foreign ministry confirmed the documents had been finalised and exchanged; the US State Department provided a short readout confirming the minerals memorandum and the strategic cooperation framework had both been concluded.

The public substance of the agreement is thin on operational detail. Neither side released the full text of the memorandum on 26 May. What is known from official readouts is that the memorandum establishes a framework for cooperation on exploration, extraction, and processing of critical minerals — a category that encompasses rare earth elements used in semiconductor manufacturing, electric vehicle production, and defence applications. The strategic cooperation agreement is described as covering a wider set of bilateral commitments, but its specific provisions have not yet been made public.

What we verified and what we could not

Monexus confirmed the following from source materials: the memorandum of understanding on critical minerals and rare earth metals was signed by Secretary of State Marco Rubio and Armenian Foreign Minister Ararat Mirzoyan on 26 May 2026 in Yerevan. A separate strategic cooperation agreement was also signed during the same visit. The signing was confirmed across multiple independent Telegram channels citing Fars News International as the wire source.

The following could not be verified from the source materials: the specific minerals or rare earth deposits covered by the agreement; any financial commitments, investment pledges, or tonnage targets; whether the memorandum is binding or non-binding; the duration or review timeline of the agreement; any commitments regarding exclusivity or supply guarantees to the United States; and whether the deal positions Armenia as a replacement or supplement to existing Chinese investment in its mining sector.

Readers should treat the strategic framing — that this represents a US pivot to arming Yerevan against Russian influence — as a plausible interpretation supported by historical context, but not as a fact established by the documents signed on 26 May 2026.

Armenia's geopolitical recalibration

The agreement is the most concrete expression yet of a directional shift in Armenian foreign policy that has been underway for several years. Armenia's security architecture has historically been anchored by a relationship with Moscow: the Collective Security Treaty Organization, Russian military presence, and energy supply arrangements all placed Yerevan within Russia's sphere of influence. That arrangement is under strain. Azerbaijan's victory in the 2020 Nagorno-Karabakh war and Russia's inability to prevent the subsequent loss of Lachin corridor access shifted the strategic calculus in Baku's favour. Russia's failures as a security guarantor were confirmed in September 2023 when Azerbaijani forces rapidly reconquered the remaining Nagorno-Karabakh territory. Armenia has since suspended its CSTO membership and begun a process of defence procurement diversification away from Russian hardware.

The minerals memorandum fits within that trajectory. Yerevan is looking for economic partners who can offer investment without the political conditionality it associates with Moscow's approach. The United States is looking for supply chain alternatives to Chinese-dominated rare earth processing — a goal that has accelerated since 2022 export control regimes made US-Chinese technology decoupling a stated policy. Armenia's geological potential in this area is real but underdeveloped; USGS survey data identifies several areas in the south of the country with confirmed rare earth mineralisation, though systematic extraction infrastructure does not currently exist. The memorandum signals intent to change that, but the timeline for anything resembling a commercially significant supply chain is measured in years, not months.

The mineral diplomacy context

The agreement must be read against a broader pattern of US engagement with mineral-rich countries outside the traditional Western alliance structure. Washington's Critical Minerals Strategy, updated in the aftermath of the 2022 supply chain disruptions, identifies diversification of rare earth sourcing as a national security priority. The US currently imports the large majority of its processed rare earths from China, which dominates both mining and the environmentally intensive processing stage. Agreements with the Democratic Republic of Congo (cobalt), Chile (lithium), and Australia (multiple rare earths) have been signed or expanded in the preceding three years. Armenia is a smaller and less proven partner in that portfolio, but it occupies a geopolitical position that those countries do not: it sits in a region where Russia has been the dominant external power for three decades, and its pivot away from Moscow carries a signal value beyond its immediate mineral output.

There is a Chinese angle to this story that the source materials do not fully illuminate. China has been a significant investor in Central Asian and South Caucasus mineral projects through its Belt and Road-linked infrastructure financing. Chinese companies hold interests in several Armenian mining operations, and Beijing has expressed interest in expanding its footprint in the region as part of its broader Eurasian integration strategy. Whether the US memorandum includes any exclusivity provisions — effectively asking Yerevan to choose Washington over Beijing on future mineral contracts — is unknown from the source materials and is one of the most significant open questions about the deal's actual scope.

What this means for Moscow

Russia has treated its South Caucasus position as a core security interest. The basing agreement at the Gyumri military base, Russia's last significant military presence in the South Caucasus, gives Moscow a physical foothold in Armenia proper. That relationship has frayed but has not been severed: Armenia has not expelled Russian forces, and the CSTO suspension remains formal rather than operational. The minerals memorandum does not, on its face, change the military calculus. But a US partnership of the kind signalled by the agreement — if it matures into genuine investment and procurement relationships — would create economic interdependencies that complicate Russia's leverage over Yerevan in ways that diplomatic statements alone cannot.

The timing of the signing, weeks before a likely Armenian political transition, adds a domestic layer. The source materials do not specify the electoral context, but reporting from regional analysts has noted that the Yerevan government faces pressure from both pro-Western reform constituencies expecting rapid movement on EU accession and nationalist constituencies sensitive to any perception of foreign dependency. The minerals deal gives the current government a visible concrete achievement. Whether it survives electoral scrutiny is a separate question that the source materials do not resolve.

The structural significance

What the signing in Yerevan represents, stripped of diplomatic language, is the application of economic statecraft to a bilateral relationship that has historically been managed through security frameworks. The United States is offering Yerevan an alternative to the Russian economic orbit: investment, technology partnerships, and a degree of strategic cover in exchange for cooperation on mineral supply chains. Armenia, having found Moscow's security guarantees wanting, is willing to engage with that offer — cautiously, without fully exiting its existing arrangements, but directionally in a new direction.

That pattern is not unique to Armenia. It is being replicated, with different partners and different commodities, across the Global South. Countries with mineral wealth and a desire to avoid exclusive dependence on any single great power are finding that the competition between Washington and Beijing for supply chain relationships creates negotiating leverage they did not previously possess. The memorandum signed on 26 May is a data point in that larger contest — not a decisive one, but a concrete one. The substance of what was agreed matters less, at this stage, than the fact that it was agreed at all.

Desk note: Monexus framed the signing as an economic statecraft story rather than a security-alignment story. Wire outlets led with the strategic cooperation agreement and the rare earth headline; we foregrounded the minerals deal as the structurally significant element while noting that the strategic cooperation framework remains opaque. Both framings are accurate; the choice reflects the desk's view that supply chain architecture is the more durable story in a region where security alignments have proven fluid.
