Ad hoc summits, on the other hand, are convened to solve specific problems or discuss specific issues as well as to create diplomatic momentum. Camp David meetings in 1978 led by Jimmy Carter to discuss peace settlement between Egypt and Israel with the participation of Egyptian leader Anwar Sadat and Israeli prime minister Menachem Begin can be regarded as an example of ad hoc summit. After twelve days of negotiations, both sides agreed on signing a peace agreement. Main objective of an ad hoc summit is to create a symbolic milestone for solution of a specific problem between states. Another example of ad hoc summits is funeral ceremonies of leaders. In these summits, leaders and their missions meet and discuss certain issues as well as develop their relations.
