Under the agreement, the two belligerents pledged to exchange prisoners of war and the dead. In addition, Armenian troops were to withdraw from Armenian-occupied territories around Nagorno-Karabakh by 1 December.

To appease the opposition, they opted for a term with less baggage: the cessation of hostilities. Parties to the conflict may consider a ceasefire for both tactical and strategic reasons. Understanding this reasoning is the key to understanding the political compromise that the parties might consider when negotiating the details of an agreement. The parties may need a pause to support their fighters, or they would like to determine the command and control of the other party over their troops, other than their willingness to negotiate politically. The question will be whether negotiators have sufficient influence within their own party or whether they are able to make relevant decisions on behalf of the party to the conflict they represent. It is also essential to understand who the negotiating teams report to and how they are engaged to ensure buy-in.
