The foreign policy of Monaco is one illustration of this accord: France has agreed to defend the independence and sovereignty of Monaco, while the Monegasque Government has agreed to exercise its sovereign rights in conformity with French interests, whilst at the same time maintaining complete independence.
The terms of the treaty upgrade France's representation in Monaco from Consulate General to that of an embassy; permit, for the first time, other countries to accredit ambassadors to Monaco; and formally recognize the succession scheme set out in the 1962 Constitution, which extends eligibility to the Prince's daughters and other family members.
In 1982, following the July 1981 signing of a new convention between Monaco and the Holy See reaffirming the close Catholic friendship and diplomatic relations which exists between the Catholic Principality and the Holy See, the rank of Monaco's diplomatic legation was elevated from that of a ministerial rank diplomatic legation to that of an embassy, with Cesar Charles Solamito, being elevated from the rank of minister plenipotentiary to ambassador extraordinary and plenipotentiary in June 1982.
This revised treaty granted the Principality the sovereign prerogative of establishing formal diplomatic relations with other sovereign states at the highest diplomatic level, that of ambassador extraordinary and plenipotentiary—for the Holy See this means at the nunzorial level, i.e., that of an apostolic nunciature headed by an apostolic nuncio (apostolic nuncios normally hold the ecclesiastical rank of archbishop).
The first, apostolic nuncio to represent the Holy See to Monaco, with residence and coterminous accreditation to the EU in Brussels, is Archbishop Andre Dupuy.
Archbishop Dupuy presented his credentials to HSH Prince Albert II on 26 September 2006.
