Azerbaijan will hold on to large parts of the Nagorno-Karabakh region.
Nagorno-Karabakh is a mountainous area that falls entirely within the borders of Azerbaijan. The region has been occupied by ethnic Armenians for decades. Under the peace deal of November 2020, Russian peacekeepers are to be present in some areas of Nagorno-Karabakh for five years.
CORRECTION: This check previously stated that Armenia has agreed to give the Nagorno-Karabakh region back to Azerbaijan. This was incorrect: Armenia has only agreed to give parts of the Nagorno-Karabakh region back to Azerbaijan.
