Surveyors Drive Metal Stakes Along the Disputed Caucasus Border
On a wind-swept ridge in the Tavush province, a team of surveyors drives a heavy steel stake into the rocky soil, marking a precise coordinate determined by decades-old Soviet military maps. A few paces away, officers from the armed forces of Armenia and Azerbaijan stand in silent observation, their uniforms bearing the insignia of states that have fought two bloody wars over these very hills. This quiet act of cartographic precision represents the most tangible progress toward a lasting peace in the South Caucasus since the collapse of the Soviet Union.
For over thirty years, the border between these two nations was not a line of administrative transit, but a lethal frontline of trenches, minefields, and sniper nests. Following Azerbaijan’s lightning military campaign in September 2023, which restored its control over the breakaway region of Nagorno-Karabakh, the geopolitical landscape of the region shifted permanently. Now, direct bilateral negotiations have replaced active hostilities, as both nations attempt to draft a comprehensive peace treaty that could redefine Eurasian trade routes and security alliances.
The Mechanics of the Border Demarcation
The ongoing peace process is anchored by a highly technical, village-by-village border demarcation effort. Rather than relying on distant international mediators, Baku and Yerevan established a joint bilateral border commission headed by their respective deputy prime ministers. The commission’s immediate task has been to translate historical documents, specifically those from the General Staff of the Soviet Armed Forces dating back to 1976, into physical markers on the ground.
This process began in earnest in the northern Tavush-Gazakh sector, where Armenia agreed to return control of four abandoned border villages—Baghanis Ayrum, Ashaghi Askipara, Kheyrimli, and Ghizilhajili—that had been occupied by Armenian forces since the early 1990s. The physical handover of these territories required the relocation of military defensive positions and the clearing of thousands of landmines. For the local populations, the sudden proximity of Azerbaijani border guards has sparked deep anxieties, yet the demarcation is viewed by both governments as an essential prerequisite to prevent future border skirmishes.
The technical challenge is immense, as the historical borders of the Soviet republics were often drawn with little regard for topography or local infrastructure. In several locations, vital Armenian infrastructure, including segments of the main highway to Georgia and a gas pipeline from Russia, runs directly through areas slated for Azerbaijani control. Resolving these micro-level disputes requires creative engineering and infrastructural bypasses, illustrating that peace in the Caucasus is as much a matter of civil engineering as it is of high diplomacy.
The Geopolitical Stakes of the Zangezur Corridor
Beyond the local border adjustments lies a far more contentious geopolitical prize: the creation of transit corridors connecting the Caspian Sea to Europe and Turkey. Azerbaijan has long demanded the opening of the "Zangezur Corridor," a proposed transport route through Armenia's southernmost Syunik province that would connect mainland Azerbaijan with its Nakhchivan exclave and Turkey. Under the Moscow-brokered November 2020 ceasefire agreement, Armenia was to guarantee the security of transport connections between the two regions, but the implementation of this clause has been a major point of friction.
For Armenia, the corridor represents a potential threat to its sovereignty and its vital border with Iran. Yerevan fears that an extraterritorial corridor controlled by Russian or Azerbaijani security forces would cut off its direct access to the south, effectively encircling the country. In response, Prime Minister Nikol Pashinyan launched the "Crossroads of Peace" initiative, proposing that all regional transport links operate under the full sovereignty and jurisdiction of the countries through which they pass.
The international stakes of this transit route are exceptionally high. Turkey strongly supports the corridor as a direct land link to the Turkic-speaking nations of Central Asia, bypassing Iran. Meanwhile, Iran has vehemently opposed any border changes in the region that would disrupt its historical trade routes through Armenia. The European Union and the United States, seeking to reduce regional reliance on Russian-controlled transit networks, have actively promoted middle-corridor trade routes that would integrate the South Caucasus into global supply chains.
Domestic Backlash and the Price of Peace
The physical demarcation of the border has triggered intense political turbulence within Armenia. The decision to cede control of the four Tavush villages without a corresponding withdrawal of Azerbaijani troops from Armenian-claimed territories sparked a massive protest movement. Led by Archbishop Bagrat Galstanyan of the Tavush Diocese, the "Tavush for the Homeland" movement mobilized thousands of citizens in Yerevan, demanding the resignation of Prime Minister Pashinyan.
Opponents of the current peace framework argue that Pashinyan’s government is making unilateral concessions under the threat of renewed military force from Baku. They point to the fact that Azerbaijani forces still occupy several strategic heights inside Armenia proper, seized during border incursions between 2021 and 2022. The domestic opposition fears that dismantling the highly fortified defense lines in Tavush will leave the country’s northern heartland vulnerable to future aggression.
Pashinyan has defended his strategy as a painful but necessary "demarcation of sovereignty." He argues that by establishing internationally recognized borders, Armenia deprives Azerbaijan of any legal pretext for military intervention. The government’s narrative presents the demarcation not as a defeat, but as the foundation of a modern, sovereign state that relies on international law rather than unsustainable military posturing.
Western Mediation Versus Regional Platforms
The diplomatic arena where this peace treaty is being negotiated has itself been a battleground of competing global influences. For several years, the European Union and the United States facilitated high-level summits in Brussels and Washington, attempting to broker a Western-aligned peace deal. These efforts, however, faced severe resistance from Moscow, which viewed Western mediation as an attempt to diminish Russian influence in its traditional backyard.
In recent months, the diplomatic center of gravity has shifted toward direct bilateral negotiations, supplemented by regional consultative platforms such as the "3+3" forum (comprising Russia, Turkey, Iran, Azerbaijan, Armenia, and Georgia). This shift reflects a growing consensus among regional powers that Caucasus security issues should be resolved by the regional actors themselves, without Western intervention.
While Russia’s influence has waned due to its preoccupation with the war in Ukraine and its failure to intervene during the 2023 Karabakh crisis, Moscow still holds significant leverage. Russian border guards continue to patrol segments of Armenia's borders, and Russia remains the sole provider of natural gas to Armenia. The final peace treaty will have to balance these competing diplomatic frameworks, ensuring that any security guarantees are acceptable to both regional giants and Western partners.
The Path to a Durable Peace Treaty
The draft peace agreement, officially titled the "Agreement on the Establishment of Peace and Relations," is reportedly close to completion, with both sides agreeing on the majority of its articles. However, several critical hurdles remain before a historic signing ceremony can take place. Chief among these is Azerbaijan’s demand that Armenia amend its constitution to remove any implicit references to the unification of Nagorno-Karabakh with Armenia, which Baku views as a latent territorial claim.
Yerevan has signaled a willingness to address this issue, but constitutional reform is a slow and politically explosive process that could take years to implement. Furthermore, the issue of mutual legal claims in international courts and the status of prisoners of war continue to complicate the final stages of negotiation. Despite these obstacles, the momentum toward peace appears stronger than at any point in the last three decades, driven by a mutual recognition that the alternative is a cycle of perpetual conflict.
As surveyors continue to drive metal stakes into the mountain soil, they are not merely drawing a border; they are dismantling the geopolitical architecture of a frozen conflict. The success of this demarcation process will determine whether the South Caucasus remains a volatile flashpoint of Eurasian rivalry or transforms into a vital land bridge of global commerce. For the first time in a generation, the physical reality of peace is being built, one marker at a time.
