Diplomat

A diplomat is a person who specializes in facilitating peaceful relations between different factions, often by serving as a negotiator or a neutral mediator of disputes. A diplomat who is a citizen of one power may be hired or appointed to professionally serve the interests of another power. 

The Dominion genetically engineered the Vorta to serve as their diplomats, scientists, and military commanders. After drinking a glass of Kanar containing voraxna poison, Weyoun remarked that his Vorta resistance to poison, "comes in handy when you're a diplomat". 

Federation, and before that United Earth, Starfleet starship commanders were sometimes called upon to serve as diplomats, whether by specific assignment or by emergent necessity. First contact and the official establishment of relations with an alien race was an important diplomatic responsibility entrusted to starship commanders. 

While in command of the USS Enterprise (NCC-1701-A) following the arrest of James T. Kirk and Leonard McCoy on suspicion of assassinating Klingon Chancellor Gorkon, Spock ordered the crew to "piece together what happened here tonight." When Pavel Chekov asked what would happen if the crew could not properly reconstruct those events, Spock replied, "Then Mr. Chekov, it resides in the hands of the diplomats." Ironically, it was Spock's own diplomatic efforts that led to the meeting of Kirk and Gorkon in the first place. 

Feeling responsible for Kirk and McCoy's arrest and show trial at the hands of the Khitomer conspiracy, Spock sought to avoid prematurely vouching for Federation approval when he began to secretly work toward Vulcan reunification with the Romulans. However, by acting without official sanction, Captain Jean-Luc Picard accused Spock of engaging in "cowboy diplomacy."
