The EU’s relationship with Baku has long been marred by disagreement over Azerbaijani domestic policy. However, the Russian invasion of Ukraine has resulted in a renewed bilateral focus on energy. A recent decision to sign a new gas deal shows that the nature of relations may truly be changing.

The war in Ukraine has encouraged Baku to pursue a policy of neutrality as it tries to maintain links with both Kyiv and Moscow. Despite this, parts of the Russian media have consistently characterised Azerbaijan’s actions as an attempt to gain at Russia’s expense.

Events over the past few weeks have seen relations between Baku and Yerevan once again hit a low point. Now focused on recent military clashes, both sides continue to hold very different perspectives on the Karabakh conflict and its future.

The opening of the Zangezur corridor will play an important role in the security of Azerbaijan’s newly liberated lands. It would cement the implementation of the November agreement and signal that the former status quo is over. This would subsequently help Baku to pursue its most ambitious undertaking in years – rebuilding the war-torn Karabakh region.

The ninth and final clause of the November 10th tripartite ceasefire agreement stated: “All economic and transport links in the region shall be unblocked. The Republic of Armenia shall guarantee the safety of transport links between the western regions of the Republic of Azerbaijan and the Nakhchivan Autonomous Republic with a view to organising the unimpeded movement of citizens, vehicles and cargo in both directions.” In practice, this condition implied the opening of the so-called “Zangezur corridor” – a 43-kilometre stretch of land along Armenia’s border with Iran. In Soviet times, this area used to provide a road and railway connection between Nakhchivan and mainland Azerbaijan. However, these routes were blocked after a war over Nagorno-Karabakh and its surrounding regions erupted in the early 1990s.

Outside observers often find it difficult to understand why the Armenian-Azerbaijani conflict has been so intractable and resisted a peaceful resolution. There is a complex combination of several complicating factors, but the ultimate culprit has been the blatant failure of diplomatic efforts, both at the level of the international community and the conflicting parties.

Skirmishes in the borderlands of Armenia and Azerbaijan raise fears of escalation.
