Argentina–Portugal relations

The current and historical relations between the Argentine Republic and the Portuguese Republic, have existed for over a century. Both nations are members of the Organization of Ibero-American States and the United Nations.

History
In 1512, Portuguese explorer João de Lisboa reached and explored Río de la Plata, and went as far south as the present-day San Matías Gulf in Southern Argentina. Several other Portuguese explorers would sail along the Rio de la Plata and would encounter other parts of present-day Argentina. In July 1816, the Portuguese Government based in Rio de Janeiro, Brazil became the first country to recognize the independence of Argentina from Spain. In August 1852, a Treaty of Friendship, Trade and Navigation was signed between Argentina and Portugal. Soon afterwards, Portuguese migrants arrived and settled in Argentina, however, Argentina never received a large number of Portuguese migrants as most preferred to immigrate to Brazil which is a Portuguese-speaking nation.

On 23 October 1910, Argentina recognized the Portuguese Republic, soon after the start of the Portuguese Revolution. In June 1947, the First Lady of Argentina, Eva Perón, paid a visit to Portugal as part of her Rainbow Tour. In July 1997, Portuguese Prime Minister, António Guterres, paid an official visit to Argentina, becoming the first Portuguese head-of-state to do so. In October 1998, Argentine President, Carlos Menem, paid a visit to Portugal to attend the 8th Ibero-American Summit in Porto. There have been several high-level visits between leaders of both nations since the initial visits.

In 2019, the European Union (which includes Portugal) and Mercosur (which includes Argentina) finalized a free trade agreement. In December 2019, Portuguese Foreign Minister, Augusto Santos Silva, paid a visit to Argentina to attend the inauguration for President Alberto Fernández.
