An International Treaty is a formal agreement between two or more countries that is legally binding under international law. These treaties can cover a wide range of issues, including trade, environmental protection, human rights, and military alliances. Countries negotiate the terms of the treaty and must ratify it through their domestic legal processes to be bound by its provisions. Once ratified, an international treaty obligates the signatory countries to adhere to its terms and can be enforced through international courts or organizations. Examples of significant treaties include the Paris Agreement on climate change and the United Nations Charter, which establishes the framework for international cooperation.
