Treaties and agreements are formal arrangements between countries or groups that outline specific terms and conditions for cooperation, peace, or trade. These documents are often negotiated by diplomats and require approval from the governing bodies of the involved parties. Treaties can cover a wide range of issues, including environmental protection, trade relations, and military alliances. Once signed, treaties become legally binding, meaning that the parties must adhere to the agreed-upon terms. If a party fails to comply, it may face diplomatic consequences or legal actions. Examples of significant treaties include the Treaty of Versailles and the Paris Agreement on climate change.
