Agrément, in international affairs, is the agreement by a state to receive members of a diplomatic mission from a foreign country.
This is presented to the head of state of the receiving state, and the diplomat is thereby accepted as a member of the diplomatic corps of the receiving state and added to a diplomatic list.
The designated person enjoys diplomatic immunity in the receiving state.
As codified by the Vienna Convention on Diplomatic Relations, the state receiving the designated diplomat may refuse agrément without giving a reason.
The absence of a timely agrément is often considered a refusal to agree to the proposed designation.
