The Holy See, as distinct from the city-state of the Vatican City, over which the Holy See has "full ownership, exclusive dominion, and sovereign authority and jurisdiction," has long been recognised as a subject of international law and as an active participant in international relations. It remains such, and indeed one observer has said that its interaction with the world has, in the period since World War II, been at its highest level ever.The diplomatic activities of the Holy See are directed by the Secretariat of State, through the Section for Relations with States.
The Holy See recognizes all UN member states, except for the People's Republic of China and North Korea. The Holy See also recognizes the State of Palestine, the only other non-UN member it recognizes besides Taiwan.
