Pro‐Memoria is a detailed statement of facts, and of arguments based on theory. It is essentially similar to a Note. Unlike a Note, however, it does not begin and end with usual diplomatic courtesy. Also, it need not be signed, since it is usually delivered either personally, following an interview, or by means of a short covering note. Sometimes it is called a memoire, or aide‐memoire or pro‐memoria when it embodies a summary of conversation.
