A multilateral treaty is an agreement between three or more countries that establishes mutual obligations and rights. These treaties are often created to address issues that affect multiple nations, such as trade, environmental protection, or security. By participating in a multilateral treaty, countries can work together to achieve common goals and promote international cooperation. Examples of multilateral treaties include the Paris Agreement on climate change and the United Nations Convention on the Law of the Sea. These treaties require signatory countries to adhere to specific terms and conditions, fostering collaboration and ensuring that all parties are accountable for their commitments.
