US President Joe Biden has written a letter to Azerbaijani President Ilham Aliyev, stressing that peace between Armenia and Azerbaijan is crucial to stabilising the region and increasing economic connectivity between Europe and Central Asia. Biden stressed that the US is strongly committed to supporting a peace treaty and that Aliyev should focus on reaching an agreement by the end of the year.
The US sent Biden's Senior Director for Europe at the National Security Council, Michael Carpenter, to personally deliver the letter to the President of Azerbaijan and further discuss its components. During the meeting, in response to the letter, Aliyev stressed that one of the main obstacles to peace was "Armenia's territorial claims against Azerbaijan".
