The Nagorno-Karabakh conflict between Armenia and Azerbaijan has long troubled the European Union’s (EU’s) neighbourhood. As a latecomer to the region, the EU played no role in the conflict in the 1990s. The subsequent establishment of bilateral relations with Armenia and Azerbaijan, including a closer engagement through the European Neighbourhood Policy (ENP) did not herald any significant changes in this respect. The bilateral relations with both countries advanced despite the military build-up, hostile rhetoric and periodic fighting. When another war erupted in September 2020, the EU was strikingly absent from the international scene in stark contrast to its rhetoric and pledges of the last two decades. Meanwhile, the Russian-brokered ceasefire did not resolve the conflict and led to further aggression demanding a more hands-on approach by the EU. In a welcome development, the EU undertook various efforts to engage the parties in a continuous dialogue for resolving the outstanding issues. In this context, the article argues for a more enhanced role of the EU in resolving this conflict based on a principled position in line with EU values and respect for international law.
