International law definition and nature

The United Nations developed this body of International Law for the purpose of promoting international peace and security.
Countries come together to make binding rules that they believe will benefit their citizens.
International Laws promote peace, justice, common interests and trade.

Thus, International Law can be considered as treaties, set of rules and agreements between countries that are binding between them.
International Law governs how nations must interact with other nations.

According to Oppenheim, International Law is a “Law of Nations or it is the name for the body of customary law and conventional rules which are considered to be binding by civilized States in their intercourse with each other

General principles of law, recognized by civilized nations, form another basis of international law

These principles include principles of justice, fairness, equity, and good faith

They provide a framework for interpreting and applying international legal rules

These rules are primarily those which govern the relations of States, but States are not the only subjects of international law

International organisations and, to some extent, also individuals may be subjects of rights conferred and duties imposed by international law
