While the Chief of Fleet Operations sees to the deployment of the fleet, and the Chief of Research and Exploration directs Starfleet's exploratory and scientific endeavors, this office oversees Starfleet's interplanetary affairs, first contact efforts, diplomatic initiatives, and colonization programs. From Starfleet Command, the staff of the Chief of Interplanetary Affairs coordinates its activities with other departments. When a starship makes contact with a new spacefaring species, for example, a report goes to the Diplomatic Corps, which then determines whether or not to pursue diplomatic initiatives. Should a survey uncover a new civilization, the CFO will forward the report to the First Contact Division. Any requirements are transmitted up the chain of command to the CIA, who then coordinates with the CFO. This office also keeps the C-n-C abreast of any developments in interplanetary affairs, and briefs officers as needed.

Talented individuals might receive a posting to one of the departments associated with this office. The Office of Personnel Management might transfer an officer with a particular talent at negotiation, for example, to the Starfleet Diplomatic Corps. Similarly, those officers who desire advanced training in the diplomatic arts can request admission to the Diplomatic School operated by the Center for Advanced Training and the Diplomatic Corps.
