Chasing a Historic Peace: Inside the Armenia-Azerbaijan Border Negotiations
The high-altitude passes of the South Caucasus, long marked by the scars of trench warfare and military checkpoints, are witnessing an unprecedented diplomatic experiment. Following decades of intractable conflict over the enclave of Nagorno-Karabakh, Armenia and Azerbaijan are engaged in intensive, direct negotiations to draft a comprehensive bilateral peace treaty. This diplomatic push represents a profound shift from the multilateral mediation frameworks of the past, as both nations attempt to bypass traditional regional power brokers to forge a direct path toward normalization.
The stakes could not be higher for a region positioned at the crossroads of European energy security and Eurasian trade corridors. The dissolution of the self-proclaimed Republic of Artsakh in September 2023 removed the primary territorial flashpoint, but it also left a complex web of unresolved issues. From the precise demarcation of a highly militarized border to the opening of regional transport links, the path to a final agreement remains fraught with historical grievances and strategic distrust.
Yet, the current momentum is distinct from previous, failed peace initiatives. Negotiators from Yerevan and Baku are working with a sense of urgency, driven by the realization that the geopolitical architecture of the region is being rapidly redrawn. As the war in Ukraine continues to distract Russia—traditionally the dominant security guarantor in the South Caucasus—both South Caucasian republics are navigating a delicate balance, seeking to secure their sovereignty while avoiding regional escalation.
The Mechanics of Demarcation: Redrawing the Border
At the heart of the ongoing negotiations is the painstaking process of border delimitation and demarcation. For over thirty years, the border between Armenia and Azerbaijan was a volatile front line rather than a recognized international boundary, characterized by fortified trenches and frequent skirmishes. The absence of mutually agreed-upon maps from the Soviet era has made the task of defining the border exceptionally difficult, with both sides referencing different historical documents from various decades of the twentieth century.
In early 2024, a significant breakthrough occurred when the two nations agreed to use the 1991 Alma-Ata Declaration as the foundational basis for border delimitation. This agreement led to the peaceful return of four deserted border villages to Azerbaijan, a move that was met with domestic protests in Armenia but hailed internationally as a concrete step toward peace. The process of physically placing border markers along these contested stretches represents the first tangible manifestation of bilateral compromise in decades.
However, hundreds of kilometers of border remain unresolved, particularly in areas where critical infrastructure, such as natural gas pipelines and international highways, crosses back and forth over the de facto boundary. Negotiators must balance technical accuracy with humanitarian considerations, ensuring that local communities are not cut off from their agricultural lands or water sources. The success of this technical delimitation process is widely viewed as a prerequisite for the signing of any formal treaty.
The Zangezur Corridor: Sovereignty versus Connectivity
Perhaps the most contentious economic and strategic bottleneck in the negotiations is the question of regional transport connectivity. Azerbaijan has consistently demanded the creation of the "Zangezur Corridor," a transport route passing through Armenia’s southernmost Syunik province to connect mainland Azerbaijan with its exclave of Nakhchivan and, by extension, Turkey. Baku has argued that this corridor should operate with minimal Armenian customs and border controls, citing the terms of the November 2020 ceasefire agreement brokered by Moscow.
Armenia, conversely, views any extraterritorial corridor through its sovereign territory as an unacceptable red line that would compromise its national sovereignty and territorial integrity. In response, Yerevan has championed its own initiative, the "Crossroads of Peace," which proposes opening all regional transport infrastructure under the jurisdiction and sovereignty of the host countries. This counter-proposal emphasizes reciprocity, suggesting that both nations could benefit from trade routes connecting the Caspian Sea to the Black Sea without sacrificing administrative control.
The geopolitical dimensions of this transport dispute extend far beyond the South Caucasus. Turkey strongly supports Azerbaijan’s corridor demands, viewing the route as a vital link in its trans-Caspian trade ambitions. Meanwhile, Iran has expressed deep reservations about any geopolitical changes near its northern border, fearing that a Turkish-backed corridor could cut off its direct land connection to Armenia and Europe. Consequently, resolving the connectivity puzzle requires a delicate diplomatic compromise that satisfies regional powers while preserving national sovereignty.
The Diplomatic Tug-of-War: Brussels, Washington, and Moscow
The diplomatic arena surrounding the South Caucasus has become a theater of intense competition among global powers, each seeking to shape the post-conflict architecture. Historically, Russia was the undisputed arbiter of regional security, maintaining a military base in Armenia and deploying peacekeepers to Nagorno-Karabakh after the 2020 war. However, Moscow's perceived inaction during the 2023 Azerbaijani offensive severely strained its alliance with Armenia, prompting Yerevan to freeze its participation in the Russian-led Collective Security Treaty Organization (CSTO) and seek western security partnerships.
In the vacuum left by shifting Russian influence, the European Union and the United States have stepped forward as key facilitators of the peace process. The "Brussels track," moderated by European Council President Charles Michel, and high-level ministerial meetings hosted by US Secretary of State Antony Blinken in Washington, have provided crucial platforms for direct dialogue. These Western-backed mediation efforts focus on establishing international mechanisms to monitor the peace treaty and ensure the protection of minority rights.
Moscow, however, remains highly suspicious of Western diplomatic involvement in what it considers its historical sphere of influence. Russian officials argue that any lasting peace agreement must be anchored in the trilateral statements brokered by Russia in 2020 and 2021, which envisioned a prominent role for Russian border guards in monitoring regional transport routes. This diplomatic rivalry complicates the negotiations, as both Yerevan and Baku must carefully navigate the competing demands of Western capitals and a resentful Kremlin.
Internal Hurdles: Constitutional Reform and Public Trust
While international diplomacy dominates the headlines, some of the most formidable obstacles to a lasting peace treaty are domestic. In Armenia, Prime Minister Nikol Pashinyan faces intense political pressure from opposition parties, the influential Armenian Apostolic Church, and diaspora organizations, who accuse his administration of making unilateral concessions to Azerbaijan. The government’s willingness to cede border territories and alter historical narratives has sparked widespread protests, highlighting the deep societal trauma left by consecutive military defeats.
A major legal hurdle has emerged regarding Armenia's constitution, which contains a reference to the 1989 declaration on the unification of Armenia and Nagorno-Karabakh. Azerbaijani President Ilham Aliyev has explicitly stated that a peace treaty cannot be signed until Armenia amends its constitution to remove these implicit territorial claims. Pashinyan has acknowledged the need for a new constitution to reflect the realities of the modern Armenian state, but organizing a national referendum on such a sensitive issue carries immense political risk.
Conversely, in Azerbaijan, the challenge lies in transitioning from a wartime political footing to a peacetime economy. Decades of state-sponsored narrative centered on the liberation of occupied territories have shaped public consciousness, and the government must now manage expectations regarding coexistence with Armenia. Furthermore, the return of hundreds of thousands of internally displaced persons to reconstructed towns in Karabakh requires massive financial investment and long-term security guarantees, making regional stability an economic necessity for Baku.
A Fragile Equilibrium: The Geopolitical Stakes of Coexistence
The ultimate success of the Armenia-Azerbaijan peace treaty negotiations will depend on the ability of both nations to transition from a zero-sum mentality to a framework of mutual benefit. A signed treaty would not only end one of the world's longest-running post-Soviet conflicts but would also unlock the economic potential of the South Caucasus. The opening of borders would allow Armenia to break its geographic isolation, establishing trade relations with Turkey and Azerbaijan, while Baku would secure a stable transit environment for its energy exports to Europe.
However, the path to implementation is fraught with potential spoilers. Localized border skirmishes, miscalculations by field commanders, or political instability in either capital could easily derail months of painstaking diplomatic work. Moreover, the absence of a robust international enforcement mechanism means that any signed agreement will rely heavily on the political will of the signatories and the restraint of regional neighbors.
As negotiators continue to refine the draft treaty, the international community remains cautiously optimistic. The transition from active conflict to diplomatic engagement in the South Caucasus offers a rare glimmer of hope in a global security landscape dominated by gridlock and escalation. Whether this fragile equilibrium can be sustained depends on whether Yerevan and Baku can transform a paper agreement into a durable, lived peace for their citizens.
