Lachin Corridor blockade §

Background

The trilateral statement of 9 November 2020 guaranteed the Lachin Corridor, a five-kilometre-wide strip of territory connecting Armenia to the residual Armenian-controlled portion of Nagorno-Karabakh, under the protection of Russian peacekeepers. The corridor was the single point of physical contact between the ~120,000 Armenian residents of NKR and the outside world: food, medicine, fuel, electricity (through cables that ran along its length), and gas (through a pipeline that ran underneath it) all transited through the corridor.

Azerbaijan maintained throughout 2021–22 that the corridor was a temporary arrangement and that its security forces had a legitimate interest in monitoring its use. By autumn 2022, emboldened by the Prague summit and the parallel weakening of the Russian peacekeeping mission as Russian forces in NKR were drawn down for redeployment to Ukraine, Baku began to escalate.

The first restriction was the March 2022 gas cutoff, which left NKR without heating for eleven days. The corridor itself was closed sporadically for periods of hours through the autumn. The full blockade began on 12 December 2022.

The event

Phase one: the "eco-protest" (12 December 2022 – 23 April 2023)

A group of self-described environmental activists, organised by entities with documented links to the Azerbaijani state, established a tent encampment on the Lachin Road at Şuşa (Shusha) with the stated aim of protesting illegal mining in NKR. The Russian peacekeepers, formally responsible for keeping the corridor open under Article 6 of the trilateral statement, did not intervene to remove the protesters. Civilian and ICRC traffic through the corridor was reduced to a trickle: the ICRC continued to operate but at sharply reduced volume, prioritising medical evacuations and emergency humanitarian movement.

The phase produced the first round of legal proceedings. Armenia applied to the ICJ for provisional measures; the Court ordered on 22 February 2023, by 13 votes to 2, that Azerbaijan "shall... take all measures at its disposal to ensure unimpeded movement of persons, vehicles and cargo along the Lachin Corridor in both directions." The order was not complied with.

Phase two: the formal checkpoint (23 April – 19 September 2023)

On 23 April 2023 Azerbaijan replaced the eco-protest with a formal Azerbaijani State Border Service checkpoint at the entrance to the corridor. Movement through the corridor, for civilians, for humanitarian organisations, for the ICRC, became subject to Azerbaijani authorisation. Through the summer of 2023, even ICRC convoys were turned back. Food and medicine shortages became acute; fuel had been exhausted; the population had no functioning hospital pharmacy by August.

Armenia returned to the ICJ for modification of the provisional measures; the Court declined to modify the order on 6 July 2023, instead reaffirming it.

The Luis Moreno Ocampo legal opinion of 7 August 2023, written by the first Chief Prosecutor of the International Criminal Court, characterised the blockade as a continuing act of genocide under the UN Genocide Convention, specifically Article II(c): "deliberately inflicting on the group conditions of life calculated to bring about its physical destruction in whole or in part." The opinion was advisory and not legally binding but politically consequential, particularly in shaping European Parliament and US Senate framing of subsequent events.

Casualty assessment

There is no consolidated count of blockade-attributable deaths. Press reports through 2023 from Armenian sources identified roughly twenty civilian deaths attributable to medical evacuation failures or fuel shortages affecting heating. The principal harm was attritional: the population lost weight, accumulated medical morbidity, and, most critically, lost confidence that any external actor would lift the siege.

Aftermath

The blockade ended on 19 September 2023 not because the road was reopened on the terms the ICJ ordered but because Azerbaijan's 24-hour military operation of 19–20 September overran the residual Armenian-controlled territory and produced the exodus that displaced the entire Armenian population through the same corridor over the following ten days. In an immediate sense the operation answered the question of why the blockade had been imposed: it was an instrument for forcing the population to a position of military and humanitarian indefensibility editorial.

Memory and politics

The international characterisation of the blockade has divided sharply. The European Parliament resolution of 5 October 2023 (491–9 with 33 abstentions) characterised the underlying course of conduct as "ethnic cleansing." The Ocampo opinion and Genocide Watch used the language of genocide. The ICJ's own framing was narrower, it found a serious risk of irreparable harm rather than a determination of unlawful conduct, but the orders themselves are binding under Article 41 of the ICJ Statute.

The Azerbaijani framing has run between three positions, none of which is generally accepted by external observers contested:

1. That the corridor was being used to smuggle weapons, justifying the security checkpoint;
2. That the eco-protest was a genuine civil-society initiative that the government did not control;
3. That the underlying cause of civilian shortages was Armenian government interference rather than Azerbaijani interdiction.

The Lachin blockade is the centrepiece of the current generation of legal proceedings against Azerbaijan, at the ICJ on the merits of the ICERD case, at the European Court of Human Rights, and through the political organs of the EU, US Congress and PACE. Whether any of these will produce binding consequence remains an open question editorial.
