The leaders of Armenia and Azerbaijan accepted the invitation of the President of the European Council Charles Michel to meet at the Eastern Partnership Summit to be held in Brussels on December 15.

On November 16, clashes broke out on the border between Armenia and Azerbaijan, which ended after negotiations between the parties with the Russian Defence Minister. Both sides reported casualties: Azerbaijan - the death of seven soldiers and wounding 10, Armenia - one dead, 13 soldiers taken prisoner, and 24 missing. The Armenian Defence Ministry acknowledged the loss of two combat positions. On the evening of November 17, a shootout took place on the border of the Tavush region of Armenia and the Tovuz region of Azerbaijan, the parties exchanged accusations of ceasefire violations. According to the Azerbaijani Defence Ministry, there was a shootout in the same area on November 18, but the Armenian Defence Ministry denies this. Residents of border villages got used to the proximity of Azerbaijani positions, but the burning of the grass and the inability to use pastures led to the ruin of pastoralists in the border areas.

At an agreed meeting in Brussels, the heads of the two states plan to discuss the situation in the region and ways to combat tensions to ensure stability in the South Caucasus, according to a publication on the website of the European Council following telephone conversations between the president of the organisation Charles Michel and the leaders of the two countries.

Armenian Prime Minister Nikol Pashinyan and Azerbaijani President Ilham Aliyev also agreed to create a line of communication between the defence ministers to prevent the escalation of the conflict.
