International treaties are formal agreements between countries that outline their rights and responsibilities. These treaties can cover a wide range of issues, such as trade, environmental protection, human rights, and security. Once negotiated and signed, countries must follow the terms of the treaty, which can help maintain peace and cooperation on a global scale. To become legally binding, treaties usually require ratification by the participating countries' governments. This process often involves legislative approval, ensuring that the treaty aligns with national laws. Examples of important international treaties include the Paris Agreement on climate change and the United Nations Charter, which establishes the framework for international relations.
