The answer to your question is given in the statement by the leaders of the three countries [Armenia, Russia, and Azerbaijan] on November 9, 2020. Russian foreign ministry official representative Maria Zakharova stated this Thursday at her weekly press briefing, when asked to comment on Armenian Prime Minister Nikol Pashinyan's statement that the Azerbaijanis of Nagorno-Karabakh (Artsakh) should return to their small homeland, and Armenia will not dispute their right to live in Karabakh.
"In particular, point 7 [of the November 9, 2020 statement] is a direct quote: ‘Internally displaced persons and refugees shall return to Nagorno-Karabakh and adjacent areas under the control of the Office of the UN High Commissioner for Refugees.’ There is nothing to add," Zakharova said.
