The region's only formal alliance, and the relationship that decided the military balance the rest of the module is arranged around.
Vigil publishes no measure of how strong or how hostile a relationship is — the description and its evidence are the record.
The same instrument South Ossetia signed, held by an entity that has spent the years since refusing what came after it.
The one part of the Russian relationship Armenia has not proposed changing — and the reason its realignment is not a departure.
A permanent declared presence, agreed in the fortnight after recognition, and the reason the 2008 settlement has never needed revisiting.
A border closed in 1993, protocols unratified in 2009, and a normalisation track that moves with Baku's.
A border Iran will not see severed, a corridor Baku wants across it, and a relationship that has been ruptured and repaired once already this decade.
A declaration of allied interaction signed two days before the invasion of Ukraine, and a relationship that has been managed, not aligned, ever since.
Severed in 2008 and never restored — while the trade and the transit that the severance was supposed to interrupt went on growing.
Existential dependence, and a politics that has repeatedly refused what the dependence is offered in exchange for.
Armenia's road to Russia and to the sea runs through a country having its own argument about which way it faces.
One of two open borders, and the one whose value rises every time the corridor question is reopened.
The market for Armenia's food, the gas for its power, the operator of its railways — and, in 2026, the first of them used.
Sustained by a state that never recognised it — the budget, the road and the army that made a de facto republic possible for three decades.
Federal money for personal loyalty — the arrangement that ended the Chechen wars and now waits on a succession.
A dependency that stopped being only economic — and by 2026 was being written into law as a single space.
A route framework signed in Washington, a strategic partnership charter, and an American stake in a corridor Armenia insists runs under its own law.
Gas the Union buys and would rather not discuss, from a supplier whose leverage grew the moment Europe stopped buying Russian.
The quietest important relationship in the region: no dispute, no ideology, and every westbound pipeline in the Caucasus running through it.
A candidacy nobody has withdrawn, attached to a process that has stopped — and a constitution that still requires pursuing it.
A membership nobody has ended, frozen by a member who says he would be glad to be expelled from it.
A membership Armenia still exercises, which the other four members have asked it to put to a vote.
An unarmed civilian mission on the border, and no guarantee behind it — which is precisely the point of it.
A dispute that changed subject rather than ending — from the status of Karabakh to the line of a border that has barely been drawn.
Descriptive records, not ratings. There is no field anywhere in this layer for relationship strength, warmth, hostility or direction of travel, and none may be added. Change is carried by the validity period, the recorded last material change and the linked events — each of which a reader can check. See the methodology.
