What term is used for communication that could result in an international agreement?

Negotiation is the term used for communication that could result in an international agreement because it inherently involves discussions and deliberations between parties aimed at reaching a consensus or an agreement on specific terms. In the context of international relations, negotiation is a critical process where diplomats, leaders, and representatives engage in dialogue to resolve issues, establish treaties, or define cooperation frameworks. This term encompasses the various methods and techniques used to reconcile interests and make compromises that lead to formal agreements.

The other options, while related to the process of forming agreements, do not specifically capture the interactive process of dialogue and compromise inherent in negotiation. A proposal refers to a suggestion put forward for consideration or discussion but does not imply the back-and-forth communication that characterizes negotiation. An agreement framework outlines the basic structure or elements of an agreement, but does not involve the dynamic interactions necessary to reach a consensus. A memorandum typically refers to a written record or communication, often used to document agreements or intentions, but it does not encompass the broader communicative and interactive process that negotiation entails.
