Diplomacy is the skill, practice, or profession of using peaceful means to establish relations between two or more parties or to avoid or resolve hostilities between parties with established relations, or to "serve as a bridge between [two] civilizations." (DIS: "The Vulcan Hello")
Diplomacy was generally considered to be the field of diplomats. In the Federation, diplomatic credentials were established through an official letter of credence. (TOS: "A Taste of Armageddon"; PIC: "The Impossible Box")
In revealing his desire for the success of Vulcan reunification, Spock explained to Jean-Luc Picard that "the union of the Vulcan and the Romulan people will not be achieved by politics or by diplomacy, but it will be achieved." (TNG: "Unification II")
The background of Captain Jean-Luc Picard in diplomacy was considered to be extensive. (TNG: "Sarek", "Man Of The People")
