Deployment of Russian peacekeepers to Karabakh §

Mandate

Article 3 of the trilateral statement provided for a Russian peacekeeping contingent along the line of contact in Nagorno-Karabakh and the Lachin Corridor. The contingent was commonly reported at roughly 1,960 personnel, with armoured vehicles and support equipment, drawn principally from Russia's 15th Motor Rifle Brigade.

The mandate was set for five years with automatic extension for further five-year periods unless one party objected six months before expiry. In practice, the deployment began immediately after the ceasefire and became the main security structure for the remaining Armenian population of Karabakh.

What the mission could and could not do

The peacekeepers prevented an immediate Azerbaijani advance into the residual Armenian-held area and enabled the return of some displaced Armenians to Stepanakert and nearby communities. They also escorted traffic, mediated incidents and maintained checkpoints.

But the mission had deep structural weaknesses. It was based on a trilateral political statement, not a UN or OSCE mandate. It did not settle status. It did not give Karabakh Armenians international legal protection independent of Russian discretion. It depended on Moscow's willingness and capacity to confront Baku if Azerbaijan tested the arrangement.

From guarantor to spectator

After Russia's full-scale invasion of Ukraine in 2022, Moscow's leverage and attention changed. Azerbaijan became more willing to challenge the peacekeeping regime, first around road access and gas supply, then through the Lachin blockade, and finally during the September 2023 operation. Russian forces did not reopen the corridor by coercion and did not prevent the collapse of NKR institutions.

The deployment's failure was not merely operational. It revealed a basic problem in Armenia's post-2020 security architecture: the only force on the ground was controlled by a power whose interests were not identical with Armenian survival in Karabakh editorial. The 2024 withdrawal completed that logic after the Armenian population had already fled.
