The Union of South American Nations (USAN; Spanish: Unión de Naciones Suramericanas, UNASUR; Portuguese: União de Nações Sul-Americanas, UNASUL; Dutch: Unie van Zuid-Amerikaanse Naties, UZAN; and sometimes referred to as the South American Union) is an intergovernmental regional organization comprising 12 South American countries.

The UNASUR Constitutive Treaty was signed on 23 May 2008, at the Third Summit of Heads of State, held in Brasília, Brazil.[9] According to the Constitutive Treaty, the Union's headquarters will be located in Quito, Ecuador.[3] On 1 December 2010, Uruguay became the ninth state to ratify the UNASUR treaty, thus giving the union full legality.[10][11] As the Constitutive Treaty entered into force on 11 March 2011, UNASUR became a legal entity during a meeting of Foreign Ministers in Mitad del Mundo, Ecuador, where they had laid the foundation stone for the Secretariat Headquarters.[12] The South American Parliament will be located in Cochabamba, Bolivia, while the headquarters of its bank, the Bank of the South are located in Caracas, Venezuela.[3]

On 4 May 2010, at a heads of state summit held in Campana, 75 km (47 mi) north of Buenos Aires, former Argentine President Néstor Kirchner was unanimously elected the first Secretary General of UNASUR for a two-year term. The new post was conceived as a first step towards the creation of a permanent bureaucratic body for a supranational union, which will eventually replace the political bodies of Mercosur and CAN. The headquarters of the secretariat is located in Quito.

After Argentina, Bolivia, Chile, Ecuador, Guyana, Peru, Suriname and Venezuela, Uruguay became the ninth nation to ratify the constitutive treaty of the organization on 1 December 2010, thus completing the minimum number of ratifications Necessary for the entry into force of the Treaty, on 11 March 2011[13][10][11] With the entry into force of the Treaty,[14] Unasur became a legal entity during the Summit Ministers of Foreign Affairs, in Mitad del Mundo, Ecuador, where the cornerstone was laid for the headquarters of the General Secretariat of the Union.[15][16]


At the Third South American Summit on 8 December 2004, presidents or representatives from 12 South American nations signed the Cusco Declaration, a two-page statement of intent announcing the foundation of the South American Community. Panama and Mexico attended the signing ceremony as observers.

The mechanics of the new entity came out of the First South American Community of Nations Heads of State Summit, which was held in Brasília on 29–30 September 2005. An important operating condition of UNASUR is that no new institutions will be created in the first phase, so as not to increase bureaucracy, and the community will use the existing institutions belonging to the previous trade blocs.

Between the 15th and 19th centuries, the Spanish and Portuguese colonization brought about the establishment and development of colonial empires in the Americas that integrated politically, economically and culturally vast extensions of the continent each with their respective metropolis.

Since the Spanish American wars of independence a trend towards the political integration of the newly born republics of Hispanic America became strong in the thinking of several independence leaders, influenced in turn by the Spanish Enlightenment and the French and American revolutions. A notable early exponent of this trend was Francisco de Miranda, who envisioned a federated republic encompassing all of Hispanic America, which he called "Colombia".

The independence war efforts saw the concurrence of integrated armies composed by Spanish Americans of diverse regions on both sides of the conflict (v.g. Patriots and Royalists), and fighting all over the territories of many future nations. For example, the Army of the Andes which was gathered in the United Provinces of the River Plate fought in Chile, Peru and Ecuador, and later integrated with Simón Bolívar's Army (which itself included troops of future Venezuela, Colombia and Ecuador) to further fight in Peru and the Upper Peru.

By the 1820s, the main proponent of a federation of the newly born republics was Simón Bolívar, although this idea was shared by many notable contemporaries, including José de San Martín and Bernardo de Monteagudo, under either republican or constitutional monarchical governments. In 1826, Bolívar summoned a conference to be held in Panama, which was to be known as the "Amphictyonic" Congress of Panama because of the parallelism with the Hellenic Amphictyonic League. The Congress was attended by Gran Colombia (including present-day Colombia, Venezuela, Panama and Ecuador), the Federal Republic of Central America (including present-day Costa Rica, Nicaragua, El Salvador, Honduras and Guatemala), the United Mexican States, and Peru. The ostensible intention was to form a defensive league that could prevent foreign expansionism and foster the interests of the Spanish American republics. The Congress' conclusions, however, were not ratified by the participants, except for Gran Colombia. Soon after, both Gran Colombia and the United Provinces of Central America fell apart and the whole of Hispanic America was balkanized by competing national governments.

By the 1990s, however, Brazil had consolidated as the most powerful country in South America (accounting for half of the regional GDP) and began to promote the notion of a united South America (a new regional framing) where Brasilia would be pivotal.[17] The project did not take hold until the United States' foreign policy priorities turned to other regions in the 2000s.


South American presidents gathered during an extraordinary meeting for the signing of the UNASUR Constitutive Treaty in May 2008 in Brasilia.

The complete integration between the Andean Community and the Mercosur nations was formalized during the meeting of South American heads of state that took place on 23 May 2008 in Brasília.[18]

In the 2004 South American Summit, representatives of twelve South American nations signed the Cuzco Declaration, a two-page letter of intent announcing the establishment of the then-named "South American Community of Nations". Panama and Mexico were present as observers. The leaders announced the intention of modeling the new community in the mold of the European Union, including a unified passport, a parliament and, eventually, a single currency. The then Secretary General of the Andean Community Allan Wagner speculated that an advanced union such as the EU should be possible within the next fifteen years.


Néstor Kirchner, first Secretary General of UNASUR

On 28 December 2005, Chilean former foreign minister Ignacio Walker proposed that the Union's former designation, the South American Community of Nations, abbreviated as CSN, be changed to South American Union; nevertheless, many members stated to him that that proposal had already been rejected to prevent confusion since its acronym of U.S.A. (Spanish: Unión Sudamericana) would be easily confused for the United States of America. In the press, the phrase "United States of South America" was bandied about as an analogy to the United States to reflect the economic and political power that the union would have on the world stage.[19][20][21][22][23][24][25]

The name was finally changed on 16 April 2007 to Union of South American Nations. The new name was jointly agreed by all member states during the first day of meeting at the First South American Energy Summit,[26] held at Isla Margarita, Venezuela.


Headquarters of UNASUR

The presidents of each member nation will have an annual meeting, which will be the top political mandate. The first meeting was held in Brasilia on 29 and 30 September 2005. The second meeting was held in Cochabamba, Bolivia, on 8 and 9 December 2006. The third meeting was held in Brasília – this meeting should have taken place in Indias (Colombia), but was postponed because of tension between Ecuador, Colombia and Venezuela. It was at this meeting that UNASUR was formalized and in which the Constitutive Treaty of the organization was signed.[27]

The foreign ministers of each country will meet once every six months. They will make concrete proposals for action and executive decision. The Permanent Representative Committee of the President of Mercosur and the Director of the Mercosur Department, the Secretary General of the Andean Community, the Secretary General of ALADI and the Permanent Secretaries of any institution for regional cooperation and integration, Amazon Cooperation Treaty Organization, Among others, will also attend these meetings.[28][citation needed]

On 9 December 2005, the Strategic Reflection Commission on the South American Integration Process was created. It consists of 12 members, whose function is to elaborate proposals that will help in the process of integration among the South American nations. These proposals were to be made at the 2nd UNASUR Meeting (2006).[29]

The Executive Committee, created at the 2nd UNASUR Meeting, was transformed into the Political Commission or Council of Deputies, in accordance with the Decisions of the Political Dialogue. The text prepared by heads of state to form UNASUR was approved at the 3rd UNASUR Meeting in Brasília on 23 May 2008. This meeting was scheduled to take place in Cartagena de Indias, Colombia, on 24–28 January 2008, but was postponed because of tensions between Ecuador, Colombia and Venezuela.

Secretary General

A Secretary General is the legal representative of the Secretariat in Quito, Ecuador. Former Ecuadorian president Rodrigo Borja was nominated to this position but resigned a few days before the formation of the USAN in May 2008. On 4 May, Néstor Kirchner of Argentina was appointed as the first Secretary General, despite resistance from Colombia, Uruguay, and Peru. After the death of Néstor Kirchner in 2010, there was a period of time when the position went unfilled, which eventually ended when María Emma Mejía Vélez was elected in March 2011. After Ernesto Samper completed his term in January 2017, UNASUR members have been unable to come to consensus on a successor.[30]

Councils and bodies

The organisations of UNASUR are:[33][34][35]

Ministerial Councils

There are twelve Ministerial Councils of the USAN.[36]

Other institutions

Council of Economy and Finance

Meeting of Ministers of Foreign Affairs of the members of Unasur.

The Economic and Financial Council of Unasur was established on 12 August 2011, in Buenos Aires, during a meeting of Finance Ministers and representatives of the Central Banks of the twelve countries of the region. Argentine Deputy Economy Minister Roberto Feletti said that the Council would study measures to strengthen regional trade in national currencies without the use of dollar. "We have reached an agreement on three axes of work and one of them is to move forward with multilateral payment mechanisms, to sustain trade and protect the volumes of reserves," Feletti said, noting that trade between countries in the region moves 120 billion dollars Yearly. "The use of national currencies, excluding the dollar, protects reserves and increases trade because there are lower transaction rates." He also detailed plans of the technical groups focused on the development and strengthening of Development Banks, such as the Andean Development Corporation (CAF) and the Bank of the South. He explained that the technicians will review the Latin American Reserve Fund (FLAR), aiming at in order to give greater capacity to intervene to the governments of the bloc in case of speculative attacks against currency or sovereign debt.[37]

Council of South American Defense

The creation of a Council of South American Defense was proposed by Brazil and discussed for the first time at a summit of the South American presidents in April 2008. The project was extensively discussed throughout 2008. The then Brazilian Defense Minister, Nelson Jobim, said in April 2008 that the Council would be formed after the "political" decision of the presidents who participated in the launch of the Union of South American Nations (UNASUR) on 23 May 2008.[38][39]

On 15 December 2008, at the extraordinary UNASUR summit, the creation of the South American Defense Council was finally approved. The defense ministers of Argentina, Brazil, Uruguay, Paraguay, Bolivia, Colombia, Ecuador, Peru, Chile, Guyana, Suriname and Venezuela. The Defense Council is responsible for developing joint defense policies, promoting the exchange of personnel among the Armed Forces of each country, conducting joint military exercises, participating in United Nations peace operations, promoting the exchange of analyzes on the world defense scenarios and the integration of industrial bases of military equipment.[40][41][42]

It was finally constituted on 21 April 2009 in Santiago, Chile.[39]

It is a permanent council composed of Ministers from UNASUR member countries. This body was created in order to constitute a space of integration concerning health, incorporating efforts and improvements from other mechanisms of regional integration, such as MERCOSUR, ORAS CONHU and ACTO, to promote common policies and coordinated activities among member countries. It is also a consultation and consensus body concerning health, which intends to delve deeply into relevant themes and strengthen public policies aimed at improving the living conditions of the inhabitants of the South American continent.

Since health is an essential right to all human beings and all societies, and it is also a vital component for the development of mankind, the Health Council seeks political and social acceptance regarding the issue, proposing health to be seen as an important booster of cooperation and integration of the bloc’s nations, intensifying the coordination of such nations and respecting diversity and interculturalism in the region.

The Health Council aims to strengthen, by establishing a South American political institution with expertise in sanitary issues, the development of solutions to challenges that transcend national borders, developing values and mutual interests among the neighboring countries, thus facilitating the interaction of the Member States health authorities through the exchange of knowledge and technology in the region. The South American Health Council (SHC) is composed of the Health Ministries of Unasur Member States. In order to achieve the Council’s goals, the Coordinating Committee – responsible for preparing propositions of Agreements and Resolutions – was created. The Presidency of the Health Council is held by the Minister of Health of the country nominated for the Pro Tempore Presidency (PTP) of Unasur. It is in charge of coordinating the activities of all its bodies and managing the Technical Secretary. The Pro Tempore President has a two-year term that may be extended for another two years, being unconditionally succeeded by a president from a different country. The SHC is supported by the Technical Secretary in charge of the Pro Tempore Presidency (PTP) and two countries of the previous and following PTP, in order to ensure the continuity of works. It is technically supported by the South American Institute for Government in Health (ISAGS). Additionally, it is composed of five Technical Groups 1- Health Surveillance and Response; 2- Development of Universal Health Systems; 3- Health Promotion and Action on Social Determinants; 4- Universal Access to Medicines; 5- Human Resources Development and Management) and six Structuring Networks (1- Network of National Institutes of Health (RINS); 2- Network of Health Technical Schools of UNASUR (RETS), 3- Network of National Institutions and Institutes of Cancer (RINC); 4- Network of Public Health Schools of Unasur (RESP); 5- Network of Disasters Risk Management; 6- Network of International Offices and International Cooperation in Health (REDSSUR-ORIS)[44]

UNASUR countries has together 410 million inhabitants and a rate of population growth of about 0.6% per year. There are several demographics such as tropical forests, the Atacama Desert and the icy portions of Patagonia. On the other hand, the continent presents regions of high population density, such as the great urban centers. The population is formed by descendants of Europeans (mainly Spaniards, Portuguese and Italians), Africans and indigenous. There is a high percentage of mestizos that vary greatly in composition according to each place. There is also a minor population of Asians, especially in Brazil. The two main languages are by far Spanish and Portuguese, followed by French, English and Dutch in smaller numbers. Economically, Brazil, Argentina and Colombia are the wealthiest and most developed nations in the continent.[citation needed]

Portuguese, Spanish, English and Dutch are the official languages of UNASUR. Spanish is the official language of Argentina, Chile, Uruguay, Paraguay, Bolivia, Peru, Ecuador, Colombia and Venezuela. Portuguese is the official language of Brazil. Dutch is the official language of Suriname; English is the official language of Guyana.[51]

Indigenous languages of South America include Quechua in Peru, Bolivia, Ecuador, Argentina, Chile and Colombia; Wayuunaiki in northern Colombia (La Guajira) and northwestern Venezuela (Zulia); Guaraní in Paraguay and, to a much lesser extent, in Bolivia; Aymara in Bolivia, Peru, and less often in Chile; and Mapudungun is spoken in certain pockets of southern Chile and, more rarely, Argentina. At least three South American indigenous languages (Quechua, Aymara, and Guarani) are recognized along with Spanish as national languages.

Other languages found in South America include, Hindustani and Javanese in Suriname; Italian in Argentina, Brazil, Uruguay, Venezuela and Chile; and German in certain pockets of Argentina, Brazil, and Chile. German is also spoken in many regions of the southern states of Brazil, Riograndenser Hunsrückisch being the most widely spoken German dialect in the country; among other Germanic dialects, a Brazilian form of East Pomeranian is also well represented and is experiencing a revival. Welsh remains spoken and written in the historic towns of Trelew and Rawson in the Argentine Patagonia. There are also small clusters of Japanese-speakers in Brazil, Colombia and Peru. Arabic speakers, often of Lebanese, Syrian, or Palestinian descent, can be found in Arab communities in Argentina, Colombia, Brazil, Venezuela and in Paraguay.[52]


An estimated 87% of South Americans are Christians[53] (69% Roman Catholic, 18% other Christian denominations mainly Traditional Protestants and Evangelicals but also Orthodoxy), accounting for ca. 19% of Christians worldwide.

Both Buenos Aires and São Paulo figure among the largest Jewish populations by urban area. Argentina also has the largest number of Muslims in Latin America, around 500,000

Japanese Buddhism, Shinto-derived Japanese New Religions are common in Brazil and Peru. Korean Confucianism is especially found in Brazil while Chinese Buddhism and Chinese Confucianism is spread throughout the continent. Due to the immigration of Indonesian workers, Suriname and Guyana have a large Hindu and Muslim community. Also Kardecist Spiritism can be found in several countries along with Afro-American religions.

In recent decades the economies of South America have been transformed into fully competitive and efficient markets. In recent years, one characteristic of the economy of UNASUR has been its excessive growth and high competitiveness, leading to world profits alongside China and India. This economic situation is marked by policies favoring market opening, aimed at the exploitation of natural resources, industrialization and a very attractive destination for investors. In spite of all this, the situation is marked by immense regional differences and by an irregularity in the distribution of the income that stands out at world level, although it is recognized as one of the regions of the world where poverty and inequality have been reduced more energetically in recent decades.

There are regions with very high industrialization, where the main economic flows move, while there are sectors where there are hardly any industries. Most of the possessions are concentrated in the hands of a minority of the population, whereas millions of individuals experience different levels of privations arriving, in extreme cases, to the absolute poverty. However, it is necessary to emphasize that poverty in South America has been reduced in a surprising way, especially in the Southern Cone and North of South America. Today, thanks to the development of many South American nations, it has allowed the world, their eyes on some governments, even forming part of economic blocs like G20 and BRICS. Although this reality is common to the entire South American group, the countries of the so-called Southern Cone (Argentina, southern Brazil, Chile, and Uruguay) present more positive socioeconomic data and high HDI rates.

The South American economy is divided between the mineral extractivism in the Amazon region and the agriculture present in practically all its States. Industrialization is of medium level to high in diverse regions, although very strong the presence of local industries of origin Foreign (multinational). The extraction and export of oil is notable in Venezuela, which owns some of the largest world reserves, in Argentina and in the Atlantic Ocean compared to the Brazilian states of Rio de Janeiro and São Paulo. Bolivia stands out for the production of natural gas, with important reserves of this matter that in recent years have led to what has been known as the "Gas War."

The richest and most industrialized regions of the continent are: São Paulo State in Brazil, where its main financial center (in its capital), the main technological centers in South America (São Carlos, São José dos Campos and Campinas) and its largest and most mobile port -; Followed by the Fluvial-Industrial axis of Paraná between Rosario and La Plata in Argentina centered in Buenos Aires (second most active port and city with higher GDP); And for the also Brazilian State of Rio de Janeiro.

Brazil and Argentina are considered the regional leaders of South America. They are the two largest nations and the two largest economies in South America. These are the only South American countries that are members of the G-20 and Brazil, specially, as member of the BRICS. They're also the largest producers and exporters of agricultural products of the continent.

The highest nominal GDP in 2017 is Brazil (8th worldwide) with 2,140,940 trillion dollars, followed by Argentina (21th worldwide) with 628,935 billion dollars, and Colombia (31st at the global level) with 306,439 billion dollars.

The highest GDP in 2017 is in Brazil (8th worldwide) with 3,216,031 trillion dollars, Argentina (27th worldwide) with 912,816 billion dollars, and Colombia (31st Worldwide) with 720,151 billion dollars.

The highest GDP per capita in 2017 is held by Chile with US$24,113, followed by Uruguay with 21,527 and Argentina with 20,047. In terms of nominal per capita GDP, the ranking is headed by Uruguay with US$15,679, Chile with US$13,576, and Argentina with US$12,503.

Common Market

Members of UNASUR and main regional highways.

One of the initiatives of Unasur is the creation of a common market, starting with the elimination of tariffs for products considered non-sensitive until 2014 and for sensitive products until 2019.[54]

The Initiative for the Integration of the Regional Infrastructure of South America is currently underway, with investments estimated at US$38 billion from the Inter-American Development Bank, the Andean Development Corporation, the National Bank for Economic and Social Development and the Financial Fund for Development of the Plata Basin.[55]

The initial integration plans through the infrastructure cooperation of UNASUR came with the construction of the Bioceanic Corridor and the Interoceanic Highway. Roads that will link more firmly the countries of the Pacific coast, especially Chile and Peru, with the countries of the Atlantic coast like Brazil and Argentina, extending highways through the continent, allowing better connections of the ports to Bolivia and more internal parts of Argentina, Peru And Brazil. The Pacific Highway, between Peru and Brazil, began to be built in September 2005, financed 60% by Brazil and 40% by Peru, and was completed in December 2010.[55]

The South American Energy Ring will interconnect Argentina, Brazil, Chile, Paraguay and Uruguay with natural gas from various sources, such as the Camisea Gas project in Peru and the Tarija gas deposits in Bolivia. Although this proposal has been signed and ratified, political and economic difficulties in Argentina and Bolivia have delayed this initiative, and to this day, this agreement remains more a protocol than a current project, since Chile and Brazil are already building LNG terminals for Gas from external suppliers.[55]

Economic development

Selection of GDP PPP data (top 10 countries and blocks) in no particular order

Presidents of the seven founding countries (Argentina, Bolivia, Brazil, Ecuador, Paraguay, Venezuela and Uruguay) officially launched the South American Bank in Buenos Aires in December 2007. The heads of all the founding countries were at the ceremony, with the exception of President Tabaré Vázquez of Uruguay. The capital will be US$7b, with Venezuela responsible for US$3b and Brazil US$2b. The headquarters will be located in Caracas with offices in Buenos Aires and La Paz.[56][57]

The Bank of the South will finance economic development projects to improve local competitiveness and to promote the scientific and technological development of the member states. Its founding charter affirms that the bank will promote projects in a "stable and equal" manner and priorities will be oriented towards reinforcing South American integration, reducing asymmetries, and promoting an egalitarian distribution of investments.

The Brazilian Minister, Guido Mantega, stated that the bank is not similar to the International Monetary Fund; it will be a credit institution similar to the World Bank.

Monetary policy

The Bank of the South (Portuguese: Banco do Sul, Spanish: Banco del Sur, Dutch: Bank van het Zuiden, English: Bank of the South) will establish monetary policy and finance development projects. One of the objectives of monetary union is to establish a Single South American currency. Support for the creation of this currency was provided in January 2007 by Peruvian President Alan García,[58] and other South American authorities expressed themselves in favor, as Bolivian President Evo Morales in April of that year, who proposed that the currency Only one denominated "Pacha" ("earth" in Quechua language), however, except for the right of each country to suggest a name for the common currency.[59]

The South American economy is divided between mineral industry in the Amazon region and agriculture, which is present in practically all member states. Industrialization is advanced in several regions, although there is a strong presence of local industries of foreign (multinational) origin. In Brazil and Argentina the level of industrialization is intense.[60]

Defense policy

The South American Defense Council (CDS) was proposed by Venezuela and Brazil to serve as a mechanism for regional security, promoting military co-operation. From the beginning Brazil, Argentina and Chile, the countries that took the leadership of the project, made clear that they did not intend to form a NATO-like alliance, but a cooperative security arrangement, enhancing multilateral military cooperation, promoting confidence and security building measures and fostering defense industry exchange. Colombia initially refused to join the defense council due to the strong military ties it has with the United States through the Plan Colombia. However, after reviewing the proposal they decided to join on 20 July 2008.[61][62]

Shortly following the signing by Colombia's President, President of Chile Michelle Bachelet appointed a working group to investigate and draft a plan for the new council. Finally, on 10 March 2009, the 12 nation members held, in Chile, the first meeting of the newly formed council.[63]

In mid-2010, UNASUR played a key role in mediating the 2010 Colombia–Venezuela diplomatic crisis. On 1 September 2010, the agency "UnasurHaití" was created to provide US$100 million in help to Haiti.[64]

On 26 November 2010, the Additional Protocol on Commitment to Democracy was signed in the city of Georgetown, Cooperative Republic of Guyana.[65] The protocol derives from the mandate established in the Buenos Aires Declaration of 1 October 2010, which affirms that member states will not tolerate a challenge to institutional authority, nor attempt to strike a legitimately constituted civilian power, adopting concrete and immediate measures in case of breach of constitutional order. It is applicable "in the event of a breach or threat of a breach of the democratic order, of a violation of the constitutional order or in any situation that endangers the legitimate exercise of power and the observance of democratic values and principles."[66]

In the event of such a situation, the Council of Heads of State and Government or the Council of Ministers of Foreign Affairs may be convened extraordinarily by the Pro-Tempore Presidency of the Union, ex officio or at the request of the affected State or another member of UNASUR, to deliberate on the application of sanctions to the affected state. Among the political and diplomatic sanctions envisaged by the Protocol, the following stand out:[66]

  • Suspension of the right to participate in the different organs and instances of Unasur[66]
  • Partial or total closure of land borders with the affected State, including suspension or limitation of trade, air and sea transportation, communications, energy supply, services and supply.

Brazilian passport with the indication of Mercosur.

Visits by South American citizens to any South American independent country of up to 90 days only require an identification document issued by the traveler's country. In November 2006, Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, and Uruguay agreed to abolish visa requirements for tourists between any of those nations.[67]

Mercosur, along with its Associate members of Bolivia, Chile, Colombia and Ecuador established that their territories together form an "area of free residence with the right to work" to all its citizens, with no additional requirements other than nationality. The Free Movement and Residence Agreement was established in the Brasília summit based in a previous document signed on 6 December 2002.[68]

Citizens of any Mercosur countries will have a simplified process in temporary residence visa of up to two years in any other member countries, with the requirements of a valid passport, birth certificate, and no criminal record. Temporary residence can become permanent if a licit means of living can be verified.

At a summit in Guayaquil, Ecuador on 4 December 2014, UNASUR general secretary Ernesto Samper announced, "We have approved the concept of South American citizenship," including the creation of a single passport.[69]

Electoral monitors

UNASUR has also initiated the creation of electoral monitor teams that could replace the monitors from the Organization of American States.[70]
