Résumé

 International Treaty is an agreement between two or more States in order to lay the foundations for joint work in one of the fields governed by international law and international relations.

   However, these conventions have not brought all solutions relating to practical problems posed by the subject of international Successive Treaties.

Key Words: Successive Treaties – Vienna conventions -  international law
