Foreign relations of the Holy See

The Holy See has long been recognised as a subject of international law and as an active participant in international relations. It is distinct from the city-state of the Vatican City, over which the Holy See has "full ownership, exclusive dominion, and sovereign authority and jurisdiction".

The diplomatic activities of the Holy See are directed by the Secretariat of State (headed by the Cardinal Secretary of State), through the Section for Relations with States.

While not being a member of the United Nations in its own right, the Holy See recognizes most UN member states – with nine exceptions (Afghanistan, Brunei, Laos, Nicaragua, North Korea, The People's Republic of China, Saudi Arabia, Somalia and Vietnam. In addition, the Holy See recognizes the State of Palestine and the Republic of China (Taiwan).

The term "Vatican Diplomatic Corps", by contrast with the diplomatic service of the Holy See, properly refers to all those diplomats accredited to the Holy See, not those who represent its interests to other nations and international bodies. Since 1961, Vatican diplomats also enjoy diplomatic immunity.

History

Since medieval times the episcopal see of Rome has been recognized as a sovereign entity. Earlier, there were papal representatives (apocrisiarii) to the Emperors of Constantinople, beginning in 453, but they were not thought of as ambassadors.^: 64 In the eleventh century the sending of papal representatives to princes, on a temporary or permanent mission, became frequent.^: 65 In the fifteenth century it became customary for states to accredit permanent resident ambassadors to the Pope in Rome.^: 68 The first permanent papal nunciature was established in 1500 in Venice. Their number grew in the course of the sixteenth century to thirteen, while internuncios (representatives of second rank) were sent to less-powerful states.^: 70 After enjoying a brilliant period in the first half of the seventeenth century, papal diplomacy declined after the Peace of Westphalia in 1648, being assailed especially by royalists and Gallicans, and the number of functioning nuncios was reduced to two in the time of Napoleon, although in the same period, in 1805, Prussia became the first Protestant state to send an ambassador to Rome. There was a revival after the Congress of Vienna in 1815, which, while laying down that, in general, the order of precedence between ambassadors would be determined by the date of their arrival, allowed special precedence to be given to the nuncio, by which he would always be the dean of the diplomatic corps.

In spite of the extinction of the Papal States in 1870, and the consequent loss of territorial sovereignty, and in spite of some uncertainty among jurists as to whether it could continue to act as an independent personality in international matters, the Holy See continued in fact to exercise the right to send and receive diplomatic representatives, maintaining relations with states that included the major powers of Russia, Prussia, and Austria-Hungary. Countries continued to receive nuncios as diplomatic representatives of full rank, and where, in accordance with the decision of the 1815 Congress of Vienna, the Nuncio was not only a member of the Diplomatic Corps but its dean, this arrangement continued to be accepted by the other ambassadors.

With the First World War and its aftermath the number of states with diplomatic relations with the Holy See increased. For the first time since relations were broken between the Pope and Queen Elizabeth I of England, a British diplomatic mission to the Holy See was opened in 1914. The result was that, instead of diminishing, the number of diplomats accredited to the Holy See grew from sixteen in 1870 to twenty-seven in 1929, even before it again acquired territorial sovereignty with the founding of the State of Vatican City.

In the same period, the Holy See concluded a total of twenty-nine concordats and other agreements with states, including Austro-Hungary in 1881, Russia in 1882 and 1907, France in 1886 and 1923. Two of these concordats were registered at the League of Nations at the request of the countries involved.

While bereft of territorial sovereignty, the Holy See also accepted requests to act as arbitrator between countries, including a dispute between Germany and Spain over the Caroline Islands.

The Lateran Treaty of 1929 and the founding of the Vatican City State was not followed by any great immediate increase in the number of states with which the Holy See had official relations. This came later, especially after the Second World War.

Since World War II, the Holy See's foreign relations are generally associated with the concept of soft power and generally seek to promote peace and humanitarian programs.^: 181 The Holy See's foreign relations are less focused on traditional state interests like state security and the like.^: 181

The Vienna Convention of 18 April 1961 also established diplomatic immunity for the Vatican's foreign diplomats. Such immunity can only be revoked by the Holy See.

After the Cuban missile crisis demonstrated the risk of nuclear war, The Holy See became convinced that it had been too reluctant to engage with the communist countries.^: 17 Through its foreign relations approach of Ostpolitik, the Vatican downplayed the role of ideological conflicts in international relations and reduced its anti-communist rhetoric.^: 17 The Vatican also sought to use this approach to make the sacraments and church public life more available in the communist countries.^: 17

Bilateral relations

The Holy See, as a non-state sovereign entity and full subject of international law, started establishing diplomatic relations with sovereign states in the 15th century. It had the territory of the States of the Church under its direct sovereign rule since centuries before that time. Currently it has the territory of the State of the Vatican City under its direct sovereign rule. In the period of 1870–1929 between the annexation of Rome by the Kingdom of Italy and the ratification of the Lateran Treaty establishing the current Vatican City State, the Holy See was devoid of territory. In this period some states suspended their diplomatic relations, but others retained them (or established such relations for the first time or reestablished them after a break), so that the number of states that did have diplomatic relations with the Holy See almost doubled (from 16 to 27) in the period between 1870 and 1929.

The Holy See currently has diplomatic relations with 184 sovereign states. These include 181 United Nations member states, the UN observer State of Palestine, the partially internationally recognized Republic of China (Taiwan), and the Cook Islands (a non-UN state in free association with New Zealand). In addition, it maintains relations with the sovereign entity Order of Malta and the supranational union European Union. The Holy See presently lacks diplomatic relations with 12 UN member states.

By agreement with the government of Vietnam, it has a non-resident papal representative to that country. It has official formal contacts, without establishing diplomatic relations, with: Afghanistan, Brunei, Somalia and Saudi Arabia.

The Holy See additionally maintains some apostolic delegates to local Catholic Church communities which are not accredited to the governments of the respective states and work only in an unofficial, non-diplomatic capacity. The regions and states where such non-diplomatic delegates operate are: Brunei, Comoros, Laos, Maldives, Somalia, Vietnam, Jerusalem and the Palestinian territories (Palestine), Pacific Ocean (Tuvalu, dependent territories), Arabian Peninsula (foreigners in Saudi Arabia), Antilles (dependent territories), apostolic delegate to Kosovo (Republic of Kosovo) and the apostolic prefecture of Western Sahara (Sahrawi Arab Democratic Republic).

The Holy See has no relations of any kind with the following states:

Kingdom of Bhutan (see Catholic Church in Bhutan)
Republic of the Maldives (see Catholic Church in the Maldives)
People's Republic of China (see Catholic Church in China)
Democratic People's Republic of Korea (see Catholic Church in North Korea)

91 embassies to the Holy See are based in Rome.

The Holy See is the only European subject of international law to have diplomatic relations with the Republic of China (Taiwan), although there have been reports of informal talks between the Holy See and the government of the People's Republic of China on establishing diplomatic relations, restoring the situation that existed when the papal representative, Antonio Riberi, was part of the diplomatic corps that accepted the Communist government military victory instead of withdrawing with the Nationalist authorities to Taiwan.^: 183 He was later expelled,^: 184 after which the Holy See sent its representative to Taipei instead.^: 187

During the pontificate of Pope Benedict XVI relations were established with Montenegro (2006), the United Arab Emirates (2007), Botswana (2008), Russia (2009), Malaysia (2011), and South Sudan (2013), and during the pontificate of Pope Francis, diplomatic relations were established with the State of Palestine (2015), Mauritania (2016), Myanmar (2017), and Oman (2023). "Relations of a special nature" had previously been in place with Russia.

Africa

Country	Formal relations begun or resumed	Notes
Algeria	1972	See Algeria–Holy See relations. During the Algerian War of 1954–1962 the Holy See did not take sides nor, in view of its pledge not to take part in temporal rivalries unless there was a mutual appeal to it, was there Vatican mediation between the French government and the Algerian rebels who requested it. After Algeria became independent, Algeria maintained diplomatic ties with the Holy See and allowed Roman Catholic priests to continue ministering to the remaining Catholics in Algeria.
Central African Republic	1967	See Central African Republic–Holy See relations. The Holy See has a nunciature in Bangui.
Democratic Republic of the Congo	1977	See Democratic Republic of the Congo–Holy See relations. The Holy See has an apostolic nunciature in Kinshasa. The DRC maintains an embassy near Vatican City.
Egypt	1947	See Apostolic Nunciature to Egypt. Pope Francis met Grand Imam of al-Azhar Ahmad al-Tayyeb in several occasions to improve relations among different faiths.

Many bishops were under the ideological influence of the previous Hutu nationalist government, and the government of Paul Kagame has tried to purge the episcopacy of hostile elements. Priests that participated in the killings behaved in a way no different from the majority of the population, a phenomenon which has led to a grave collective and spiritual guilt, and has led to the growth of Evangelical churches and Islamic organizations. In part, this has been attributed to an ethnic-based liberation theology, which was denounced by the Holy See in the 1970s and 1980s.
Sudan	1969	The Holy See has a nunciature in Khartoum. Sudan has an embassy in Rome. "Pope Urges Sudan to End Military Campaign in Darfur"

When the Chinese Communist Party won the Chinese Civil War and established the People's Republic of China (PRC) in 1949, the Holy See chose not to move its diplomatic representative to Taipei, Taiwan where the government of the Republic of China had retreated to. However, the Communist government expelled it, and the Holy See's diplomatic mission was then transferred to Taipei in 1951. In 1971, when the seat of China at the United Nations was adjudicated to the government of the PRC, the Holy See continued to maintain formal diplomatic relations with China through the ROC.^: 181 Since 1971, the Holy See maintains a downgraded Apostolic Nunciature in Taipei, but without a Nuncio. The mission is headed only by a chargé d'affaires who carries on the business of the diplomatic mission.

On 21 July 2008, the Australian Government announced that it would appoint Tim Fischer as the first resident Ambassador to the Holy See. According to the Australian Foreign Ministry, this marked a significant deepening of Australia's relations with the Vatican since it would allow Australia to expand dialogue with the Vatican in areas including human rights, political and religious freedom, inter-faith dialogue, food security, arms control, refugees and anti-people trafficking, and climate change.

Activities of the Holy See within the United Nations system

Since 6 April 1964, the Holy See has been a permanent observer state at the United Nations. In that capacity, the Holy See has since had a standing invitation to attend all the sessions of the United Nations General Assembly, the United Nations Security Council, and the United Nations Economic and Social Council to observe their work, and to maintain a permanent observer mission at the UN headquarters in New York. Accordingly, the Holy See has established a Permanent Observer Mission in New York, has sent representatives to all open meetings of the General Assembly and of its Main Committees, and has been able to influence their decisions and recommendations.

Relationship with Vatican City

Although the Holy See is closely associated with Vatican City, the independent territory over which the Holy See is sovereign, the two entities are separate and distinct.

The State of the Vatican City was created by the Lateran Treaty in 1929 to "ensure the absolute and visible independence of the Holy See" and "to guarantee to it an indisputable sovereignty in international affairs" (quotations from the treaty). Archbishop Jean-Louis Tauran, the Holy See's former Secretary for Relations with States, said that the Vatican City is a "minuscule support-state that guarantees the spiritual freedom of the Pope with the minimum territory."

The Holy See, not Vatican City, maintains diplomatic relations with states, and foreign embassies are accredited to the Holy See, not to Vatican City State. It is the Holy See that establishes treaties and concordats with other sovereign entities and likewise, generally, it is the Holy See that participates in international organizations, with the exception of those dealing with technical matters of clearly territorial character, such as:

European Conference of Postal and Telecommunications Administrations (CEPT)
European Telecommunication Satellite Organization (EUTELSAT)
International Grains Council (IGC)
International Institute of Administrative Sciences (IISA)
International Telecommunications Satellite Organization (ITSO)
International Telecommunication Union (ITU)
Interpol
Universal Postal Union (UPU)

Under the terms of the Lateran Treaty, the Holy See has extraterritorial authority over various sites in Rome and two Italian sites outside of Rome, including the Pontifical Palace at Castel Gandolfo. The same authority is extended under international law over the Apostolic Nunciature of the Holy See in a foreign country.

Diplomatic representations to the Holy See

Of the diplomatic missions accredited to the Holy See, 91 are situated in Rome, although those countries, if they also have an embassy to Italy, then have two embassies in the same city, since, by agreement between the Holy See and Italy, the same person cannot at the same time be accredited to both. The United Kingdom recently housed its embassy to the Holy See in the same chancery as its embassy to the Italian Republic, a move that led to a diplomatic protest from the Holy See. An ambassador accredited to a country other than Italy can be accredited also to the Holy See. For example, the embassy of India in Bern, accredited to Switzerland and Liechtenstein, is also accredited to the Holy See, while the Holy See maintains an Apostolic Nunciature in New Delhi. For reasons of economy, smaller countries accredit to the Holy See a mission situated elsewhere and accredited also to the country of residence and perhaps other countries.

Rejection of ambassadorial candidates

It has been reported on several occasions that the Holy See will reject ambassadorial candidates whose personal lives are not in accordance with Catholic teachings. In 1973, the Vatican rejected the nomination of Dudley McCarthy as Australia's non-resident ambassador due to his status as a divorcee. According to press accounts in Argentina in January 2008, the country's nominee as ambassador, Alberto Iribarne, a Catholic, was rejected on the grounds that he was living with a woman other than the wife from whom he was divorced. In September 2008, French and Italian press reports likewise claimed that the Holy See had refused the approval of several French ambassadorial candidates, including a divorcee and an openly gay man.

Massimo Franco, author of Parallel Empires, asserted in April 2009 that the Obama administration had put forward three candidates for consideration for the position of United States Ambassador to the Holy See, but each of them had been deemed insufficiently anti-abortion by the Vatican. This claim was denied by the Holy See's spokesman Federico Lombardi, and was dismissed by former ambassador Thomas Patrick Melady as being in conflict with diplomatic practice. Vatican sources said that it is not the practice to vet the personal ideas of those who are proposed as ambassadors to the Holy See, though in the case of candidates who are Catholics and who are living with someone, their marital status is taken into account. Divorced people who are not Catholics can in fact be accepted, provided their marriage situation is in accord with the rules of their own religion.

Treaties and concordats

Since the Holy See is legally capable of ratifying international treaties, and does ratify them, it has negotiated numerous bilateral treaties with states and it has been invited to participate – on equal footing with States – in the negotiation of most universal International law-making treaties. Traditionally, an agreement on religious matters between the Holy See of the Catholic Church and a sovereign state is called a concordat. This often includes both recognition and privileges for the Catholic Church in a particular country, such as exemptions from certain legal matters and processes, issues such as taxation, as well as the right of a state to influence the selection of bishops within its territory.
