Agreements between nations are formal documents that outline the terms of a relationship between two or more countries. TREATIES, PACTS, and ENTENTES are all types of agreements between nations. TREATIES are legally binding documents that are negotiated and signed by two or more countries. PACTS are similar to TREATIES, but they are less formal and not necessarily legally binding. ENTENTES are agreements between two or more countries that are not legally binding, but are still considered to be important for diplomatic relations.
