A treaty is an agreement between two or more states or international organizations that is legally binding under international law. Treaties can cover a wide range of topics, including peace, trade, environmental protection, human rights, and the regulation of armaments. Treaties are negotiated by the parties involved and are often concluded with a formal signing ceremony. Once a treaty has been signed and ratified, it becomes a part of the international legal system and is enforceable through the courts and other mechanisms established by international law.
