A described arrangement, not a rating. Vigil publishes no measure of how strong, warm or hostile a relationship is, and no relationship on this site carries a score, a trend or a direction of travel. What is recorded is what the arrangement covers, when it began, what has changed it, and how firmly each of those is established.
Relationship record

Armenia → Iran in the Caucasus

One of two open borders, and the one whose value rises every time the corridor question is reopened.

Economic dependencyActiveSince 1993
In short

Armenia's dependence on Iran as one of only two usable land routes to the outside world, its borders with Türkiye and Azerbaijan being closed. The relationship is careful and valued on the Armenian side, and Iran treats any change to the border configuration as a red line of its own.

The parties

A directional arrangement: the two parties do not hold the same position in it. Authored once and read from both ends.

Status

Active

In force and operating. Says nothing about how well it is working, or about which way it is heading.

What the arrangement covers

TradeEnergyInfrastructure

Categories the arrangement is documented to include. Not a measure: a relationship covering more of them is described in more detail, not held more firmly.

Summary

Two of Armenia's four land borders are closed — with Türkiye since 1993 and with Azerbaijan — leaving Georgia and Iran as the only routes and making Armenian external access structurally narrow. Iran is therefore not an optional partner but one of two available ones, which is why Armenian governments across the political spectrum have kept the relationship careful and uncontroversial regardless of their orientation elsewhere. Iran's own interest runs the other way and is strategic rather than commercial: it borders both Armenia and Azerbaijan, trades with both, and opposes any corridor arrangement that would cut its land link to Armenia or place outside powers' personnel on its frontier — which, in its reading, the TRIPP arrangement would.

Why it matters

It is the constraint that makes Armenia's westward turn expensive. A state with two open borders cannot align in a way that jeopardises either, and the southern one belongs to a power that has already stated where its limits lie on the corridor question the peace process has not solved.

Systems it depends on

LogisticsArmenian external access — two borders open, two closed

Canonical logistics records. They carry the corridors, nodes, dependence and disruption history that this relationship rests on and does not restate.

What remains unknown

  • `validFrom` is anchored to the closure of the Armenia–Türkiye border in 1993, the point from which this module dates Armenia's structurally narrow access. The bilateral relationship itself predates that and this module does not record when it began.
  • Trade volumes and their share of Armenian external commerce are not published by this module, so the dependence is recorded as structural rather than measured.
  • How far Iranian objections have actually shaped the corridor negotiation, as opposed to being stated alongside it, is not established.
