Diplomatic Missions, Consular Relations and Spain’s Cooperation Policy
Diplomatic Missions and Spanish Embassies
Q1. The Diplomatic Mission (Vienna 1961) and Spanish Embassies
The 1961 Vienna Convention on Diplomatic Relations is the main treaty on diplomatic law. It regulates permanent diplomatic missions. It is declaratory: it writes down old customary rules, and it also adds some new ones. A diplomatic mission is a group of people and material resources that one State (the sending State) places in another State (the receiving State) to represent it. Its basic principle is mutual consent: no State is obliged to have diplomatic relations or to accept an embassy, and both States agree on its rank and size.
Functions of a Diplomatic Mission
1. To represent the sending State.
2. To protect its interests and those of its nationals, within the limits of international law.
3. To negotiate with the receiving State.
4. To find out, by lawful means, what happens in the receiving State and to report to its own government.
5. To develop economic and cultural ties as well as friendly relations.
The limit is clear: the mission must respect local laws and never interfere in the internal affairs of the receiving State.
Staff
There are four groups: Head of Mission, Diplomatic Staff, Administrative and Technical Staff, and Service Staff. The Head of Mission (ambassador, envoy or chargé d’affaires) needs the placet, which the receiving State can refuse without giving reasons. The receiving State can declare any member of the mission persona non grata at any time, and the sending State must then recall that person.
Privileges and Immunities
They exist under the principle ne impediatur legatio: they are not for the personal benefit of the individual, but so that the mission is not hindered. The premises, the archives and the official correspondence are inviolable, and the diplomatic pouch cannot be opened or detained.
Spanish Embassies
They depend on the Ministry of Foreign Affairs, European Union and Cooperation (MAUEC), under the principle of unity of foreign action. They are headed by an Ambassador appointed by Royal Decree (agreed by the Council of Ministers). The staff includes Career Diplomats (the Diplomatic Career: Third Secretary, Second Secretary, First Secretary, Embassy Counsellor, Minister Plenipotentiary, Ambassador).
Consular Offices and the 1963 Vienna Convention
The 1963 Vienna Convention on Consular Relations regulates consular offices. The consular institution was born linked to trade and to the protection of merchants and sailors abroad. A consular office is a body of the public administration of one State, located in the territory of another State. It is not representative: it does not represent the State politically. Consular relations are established by mutual consent, but they are independent from diplomatic relations. Having a consulate does not mean recognising a State or a government, and it does not require an embassy (and the other way round). Each office works in a consular district, unlike an embassy, whose jurisdiction covers the whole territory of the receiving State.
Functions
- Protecting the interests of the State and its nationals.
- Promoting economic, commercial, cultural and scientific relations.
- Gathering information by lawful means.
- Helping nationals: in cases of arrest the receiving State must notify the consulate and the consul can visit the detainee; protection of minors and incapacitated people; successions.
- Issuing passports and visas; notarial and civil registry functions (births, marriages, deaths).
- Serving judicial documents and processing letters rogatory.
- Inspecting and controlling ships and aircraft of the sending State.
Staff
A consulate is headed by a Consul General, Consul, Vice-Consul or Consular Agent (these are the four ranks, from highest to lowest). The head can be a career consul (a paid civil servant of the sending State) or an honorary consul (usually an unpaid local businessperson with less protection). To start working, he needs a letter patent from his own State (his appointment) and an exequatur from the receiving State (the permission to work). He works with consular officials and employees, who do the daily procedures, and with service staff, such as drivers and cleaners.
Privileges and Immunities
They are weaker than those of diplomats and are functional (ratione materiae). The premises are inviolable only in the part used exclusively for consular work. The archives are always inviolable. Career officials cannot be arrested except for serious crimes, and they have immunity only for official acts.
International Development Cooperation
International development cooperation is the set of actions by States and international organisations to help developing countries reduce poverty and inequality and achieve sustainable development. Today it is framed by the 2030 Agenda. It is financed mainly through ODA (Official Development Assistance), with an international target of 0.7% of Gross National Income (GNI). The EU is the largest ODA donor in the world, and Spain has always defended that middle-income countries should keep receiving ODA, because they still suffer from inequality and vulnerability.
Humanitarian Aid versus Development Cooperation
Humanitarian aid is different. It is short-term help to save lives and relieve suffering in wars, natural disasters or refugee crises. It follows four principles: humanity, neutrality, impartiality and independence. Development cooperation, by contrast, is long-term and aims at structural change (schools, health systems, strong institutions).
Spanish Framework
Spanish framework. The legal basis is Law 1/2023 on Cooperation for Sustainable Development and Global Solidarity. The four-year Master Plan (Plan Director) sets the priorities. The Ministry of Foreign Affairs leads the policy through the Secretary of State for International Cooperation.
AECID
AECID (Spanish Agency for International Development Cooperation) is the main executing body. It is attached to the Ministry through the Secretary of State for International Cooperation and is led by a Director.
- Functions: to design, manage and execute cooperation policy; to finance projects with partner countries; to work with NGOs; to coordinate humanitarian action in emergencies; to promote cultural and scientific cooperation.
- Staff and structure: headquarters in Madrid and a network abroad: Technical Cooperation Offices (inside embassies), Cultural Centres and Training Centres (mainly in Latin America).
- Resources: the State budget (ODA funds), EU funds, and collaboration with NGOs, regional governments and international organisations.
Spain, Morocco, Ceuta and Melilla
1. Historical Background
Morocco was under French and Spanish control and became independent in 1956. King Mohammed V and the Istiqlal Party promoted the idea of Greater Morocco. They believed that Morocco should include Western Sahara, Mauritania and parts of Algeria and Mali. However, France refused to change the borders because these territories had important natural resources, and they also desired to maintain their political and economic influence and protect their strategic interests.
In 1975, King Hassan II organised the Green March into Spanish Sahara. Spain withdrew and transferred the administration of the territory to Morocco and Mauritania. However, the Sahrawi people wanted independence and were supported by Algeria. Today, Morocco controls most of Western Sahara, but its status remains disputed.
Morocco also claims Ceuta and Melilla, while Spain considers them an integral part of its territory, as they have been part of Spain since the Middle Ages.
2. The Migration Crisis
On 30 July 2026, around 80,000 migrants entered Ceuta from Morocco in a short period. This created a serious diplomatic crisis between the two countries.
According to the speakers, Morocco may have used migration as a political tool to test Spain’s weaknesses and put pressure on its government. The crisis showed that Spain depends partly on Morocco to control migration.
The large number of arrivals in such a short period put considerable pressure on Spain’s border security forces and created a serious challenge for the authorities. The crisis also increased tensions between Spain and Morocco and showed how quickly migration can become a major political and security problem.
4. The Defence of Ceuta and Melilla
Ceuta and Melilla are strategically important because of their location in North Africa. Their security is connected to migration, drug trafficking and possible military threats. The admiral explained that Spain has modern military equipment, including frigates, drones and missiles. However, the speakers argued that Spain needs to invest more in defence. They also discussed Article 5 of NATO, which states that an armed attack against one member is considered an attack against all. However, the exact response of the other members to an attack on Ceuta or Melilla is uncertain. Therefore, Spain must be prepared to defend itself.
5. International Relations
The conflict is also influenced by international politics. Algeria supported the Sahrawi independence movement and was historically close to the Soviet Union. Today, Morocco has strong relations with the United States and Israel. The speakers warned that Morocco is not necessarily a completely reliable ally of the United States, because every country mainly defends its own interests. Spain and the European Union also cooperate with Morocco to control migration from North Africa and the Sahel. However, the speakers criticised this policy because they believe Morocco can use migration to put political pressure on Europe. European countries have different migration problems, making it difficult to agree on a common policy.
6. The Future and Possible Solutions
The speakers believe that Morocco’s control of Western Sahara is likely to continue, although the Sahrawi people still demand independence. The conflict is therefore not fully resolved. Ceuta and Melilla will probably remain sources of tension between Spain and Morocco. In my opinion, Spain needs a firm but balanced policy. It should strengthen border security, invest more in defence, fight drug trafficking and respond clearly to Moroccan pressure. At the same time, Spain should maintain diplomatic relations with Morocco and cooperate with the European Union and NATO.
