International conventions are treaties or agreements between states (the primary actors in international law). See Malcolm N. Shaw, International Law 88 (5th ed., Cambridge, 2003). International convention is used interchangeably with terms like international treaty, international agreement, compact, or contract between states. Conventions may be of a general or specific nature and between two or multiple states. Conventions between two states are called bilateral treaties; conventions between a small number of states (but more than two) are called plurilateral treaties; conventions between a large number of states are called multilateral_treaties.
