Agrément
Agrément is the receiving state’s prior consent to the appointment of a proposed ambassador as head of mission.
The sending state seeks consent before accreditation. Under Article 4 of the Vienna Convention on Diplomatic Relations, the receiving state need not provide reasons for refusing agrément.
The process preserves the receiving state’s ability to accept the person who will represent another state at ambassadorial level.
Before announcing an ambassador’s appointment, a foreign ministry seeks agrément through diplomatic channels, then proceeds with the applicable appointment and credentials process.
Distinguish pre-appointment agrément from presenting credentials and from a later persona non grata declaration.

- Persona Non Grata
Persona non grata is the formal designation by which a receiving state declares that a diplomatic agent is no longer acceptable. The receiving state may make the declaration without explaining its decision, after which the sending state is expected to recall the person or end that person's functions with the mission.
- Ambassador
An ambassador is a state's highest-ranking diplomatic representative accredited to another state or, in a different institutional form, to an international organization. An ambassador normally leads an embassy or permanent mission, represents the sending state's positions, and acts under the authority and instructions of the sending government.
