May 2023 will be remembered as the month of intensive negotiations between Armenia and Azerbaijan. It started from the four-day summit in Washington, where the two ministers of foreign affairs with their teams were engaged in face-to-face interactions to discuss the text of the Armenia-Azerbaijan peace agreement. Ten days later, Armenian and Azerbaijani leaders met in Brussels, revitalizing the Brussels format, which had been stalled in September 2022. As a result of the Brussels summit, the sides reiterated the mutual recognition of territorial integrity based on the Alma-Ata declaration. For the first time, they agreed to use exact numbers when describing each other’s territories. This step dispersed fears in Azerbaijan that despite signing the Prague statement in October 2022 and recognizing Azerbaijani territorial integrity based on the Alma-Ata declaration, Armenia may still avoid recognizing Artsakh (Nagorno Karabakh) as part of Azerbaijan, arguing that Artsakh was not part of Azerbaijan on December 21, 1991, when the Alma-Ata declaration was signed. A few days later, the Armenian Prime Minister confirmed that Armenia recognizes Artsakh as part of Azerbaijan during his speech at the summit of the Council of Europe. On May 22, he reiterated this position during a press conference in Yerevan. On May 19, Armenian and Azerbaijani foreign ministers met in Moscow to continue discussing a peace agreement, while President Aliyev and Prime Minister Pashinyan met in the Russian capital on May 25. The meeting did not bring any tangible result, except the agreement to hold another trilateral meeting in Moscow at the level of deputy prime ministers to continue discussions on the opening up of communications.
