Caucasus developments — 13 September 2026

A quiet week with one procedural datum in it. On 9 September Azerbaijan's foreign minister, Jeyhun Bayramov, said the two governments have an agreement and a mutual understanding that border delimitation will begin at the harder northern sections, from the point where the Azerbaijani, Armenian and Georgian borders meet, and proceed north to south. That is a sequencing decision about method, and it is worth recording because the delimitation file has produced almost nothing since the dozen kilometres agreed in the Tavush direction in 2024 — but it is a decision about how to start, not a section started. Everything else held: the peace agreement is initialled and unsigned with the constitutional precondition unwithdrawn, nothing has been built on the Armenian section of the TRIPP route, no new instrument was recorded between Moscow and either Georgian entity, and no verified development appeared in the North Caucasus file.

Baku and Yerevan agree where to start delimiting, which is not the same as starting

Azerbaijan's Minister of Foreign Affairs, Jeyhun Bayramov, said on 9 September that there is an agreement and mutual understanding between Azerbaijan and Armenia that the delimitation of the state border will begin from the more difficult northern section, at the point where the borders of Azerbaijan, Armenia and Georgia intersect, and proceed from north to south. He said the two state commissions — headed on the Azerbaijani side by Deputy Prime Minister Shahin Mustafayev and on the Armenian side by a deputy prime minister — meet and hold discussions regularly, and referred to an upcoming meeting with his Armenian counterpart without giving a date. No joint statement, protocol or Armenian confirmation of the sequencing was identified in the window, and no new section of border has been delimited.

Why it matters. Since the commissions were created, one section has been delimited: about a dozen kilometres in the Tavush direction in 2024, with four villages transferred. The rest has been a process with a legal baseline — the 1991 Alma-Ata Declaration and the Soviet-era maps in force at the time — and no agreed order of work. A sequencing decision is therefore a real procedural step, and the choice it records is the interesting part: starting at the hardest sections rather than the easiest is the opposite of confidence-building by increments, and it is consistent with two governments that want the file finished rather than demonstrated. It is also, on its own, worth very little. Nothing has been surveyed, no section has been opened, no timetable exists, and the Armenian-administered enclaves — the hardest problem on the line, one of them astride Armenia's principal north–south road — are untouched. The standing question asks whether delimitation has extended beyond Tavush, and the answer this week is still no. The observable is a second delimited section with an agreed alignment, not a further statement about where one would begin.

Confidence: Moderate High for the statement itself, which was made publicly by a named minister and reported by Azerbaijani, Armenian and regional outlets in consistent terms. Moderate for it being a bilateral agreement rather than an Azerbaijani characterisation of one: no Armenian confirmation, joint statement or published protocol was identified in the window, and this file has a history of positions described differently by each side. No date for the next commission meeting was given and none is inferred here.

Standing watch items reviewed — no material change identified

Has delimitation extended beyond the 2024 Tavush section? — No. A sequencing agreement was stated on 9 September; no second section has been taken up, no ground changed hands and the enclaves remain untouched.
Has the initialled peace agreement been signed? — Unsigned. No signature, no date, no published constitutional draft and no statement withdrawing the constitutional precondition was identified.
Has TRIPP moved from framework and survey into construction? — Nothing built on Armenian territory, no funding decision for the Armenian section announced, and no project named under the 31 August statement's "further practical steps".
Is Armenia's realignment becoming institutional rather than declaratory? — No CSTO council decision in this window — the Article 25 question sits with the November council — no contribution payment, no proposal on the Gyumri lease, and no Western instrument moved from partnership to guarantee.
Is Russian integration of the two Georgian entities deepening? — No new instrument, ratification or transfer of competence identified in either entity. The Russian federal vote of 20 September falls after this cutoff.
Does the Chechen succession question produce an observable event? — No verified development in the succession file and no incident of structural significance identified in the window.

Watch questions this review updated

Does the Chechen succession question produce an observable event?Unchanged — No verified development in the Chechen succession file was identified, and no incident of structural significance was recorded in Dagestan or elsewhere in the North Caucasus during the window. This is the position in every review since the module’s first.
Has delimitation extended beyond the 2024 Tavush section?Movement — Azerbaijan’s foreign minister said on 9 September that the two sides have agreed to work from the tripoint with Georgia southward, beginning with the harder northern sections. That is a sequencing agreement about method, and the question asks whether delimitation has extended beyond Tavush: it has not. No second section has been taken up, no new ground has changed hands and the enclaves remain untouched.
Has the initialled peace agreement been signed?Unchanged — Unsigned. No signature, no date, no published constitutional draft, and no statement by any Azerbaijani official withdrawing the constitutional precondition was identified. The delimitation sequencing agreed on 9 September concerns the border commissions and not the treaty text.
Has TRIPP moved from framework and survey into construction?Unchanged — Nothing has been built on Armenian territory, no funding decision for the Armenian section was announced, and no project was named under the “further practical steps” language of the 31 August joint statement. The stage is unchanged: instruments and surveys, no works.
Is Armenia's realignment becoming institutional rather than declaratory?Unchanged — Checked against the four standing facts. No CSTO council decision falls in this window — the Article 25 question sits with the November council — no contribution payment was reported, no proposal on the Gyumri lease was made by either party, and no Western instrument moved from partnership to guarantee. The realignment remains declaratory on this evidence.
Is Russian integration of the two Georgian entities deepening?Unchanged — No new instrument, ratification or transfer of competence was identified in either entity during the window. The Russian federal vote due on 20 September, at which polling stations are to operate in both entities, falls after this cutoff and is not treated as having happened.
