Abstract
The most frequent means of creating international rules is the conclusion of agreements. These are also called treaties, conventions, protocols, covenants, ‘acts’, etc. The terminology varies but the substance is the same: they all denote a merger of the wills of two or more international subjects for the purpose of regulating their interests by international rules. This chapter discusses the notion and types of treaty, the making of treaties, reservations, grounds of invalidity, interpretation, and termination in light of the 1969 Vienna Convention on the Law of Treaties, which is one of the prominent achievements of the ILC for the codification and progressive development of international law.
