`treaty` means an international agreement concluded in writing between States and governed by international law, whether contained in a single act or in two or more related agreements, and whatever its particular name. Vienna Convention on the Law of Treaties, 23 May 1969, art. 2(1)(a), 1155 U.N.S.T.331. A treaty is negotiated by a group of countries, either by an organization created for that specific purpose or by an existing body such as the United Nations (UN) Disarmament Council. The negotiation process can take several years, depending on the subject of the treaty and the number of participating countries. At the end of the negotiations, the contract will be signed by the representatives of the governments concerned. The terms may require that the treaty be ratified and signed before it becomes legally binding. A Government ratifies a treaty by depositing an instrument of ratification at a place specified in the treaty; The instrument of ratification is a document containing a formal confirmation that the Government accepts the provisions of the Treaty. The ratification process varies according to the laws and constitutions of each country. In the United States, the president can only ratify a treaty after receiving the “advice and approval” of two-thirds of the Senate.
International treaties are the most common means of creating international rules or norms to which States and other actors in the international community should adhere. Their importance has increased considerably in the context of modern international law. The quality of the application of international law has often been called into question, which has been regulated by the increasing treaty-making process. In addition, the universality of human rights can be considered an achievement through international treaties. International law holds that nothing can be done without or against the will of a sovereign State. International law in this sense can also be described as a meeting place for the need to make international commitments. The present paper therefore fundamentally examines the characteristics and significance of international treaties from the point of view of international law. In addition, it was stated that the issue of reservations in the treaty process was becoming less and less important because it isolated the State from the world stage. International agreements that enter into force on a constitutional basis other than with the approval of the Council and the Senate are “international agreements other than treaties” and are often referred to as “executive agreements”.
