Portugal–São Tomé and Príncipe relations refers to the diplomatic relations between the Portuguese Republic and São Tomé and Príncipe. Both nations are members of the Community of Portuguese Language Countries and the United Nations.

History

In 1470, Portuguese explorers, João de Santarém and Pêro Escobar discovered the islands uninhabited.^[1] The territory was soon incorporated into the Portuguese Empire. In order to cultivate the islands, the Portuguese brought people as slaves from the African mainland to work the cocoa and sugar plantations on the islands. São Tomé and Príncipe became important staging post for the Atlantic slave trade.^[2]

In 1972, a São Toméan nationalist political party, the Movement for the Liberation of São Tomé and Príncipe (MLSTP), was created by exiles based in Equatorial Guinea with the intent of creating an independent nation. After the Carnation Revolution of 1974, the new Portuguese regime was committed to the dissolution of its overseas colonies. In November 1974, their representatives met with members of the MLSTP in Algiers and worked out an agreement for the transfer of sovereignty. Portugal granted independence to São Tomé and Príncipe on 12 July 1975.^[2] That same day, both nations established diplomatic relations.^[1]

Since independence, relations between Portugal and São Tomé and Príncipe have remained strong. There are many cultural similarities between both nations. There have also been several high-level visits between leaders of both nations and both countries work closely together within the Community of Portuguese Language Countries.

Bilateral agreements

Both nations have signed a few bilateral agreements such as an Agreement for Cooperation and Friendship (1975); Agreement on Trade (1978); Agreement on Cultural Cooperation (1978); Agreement on Maritime Transport (1978); Agreement on Migration (1978); and an Agreement on Technical Cooperation in Police Training (1989).^[1] In September 2022, Portugal and São Tomé and Príncipe signed a new cooperation agreement for defence, bolstering training and maritime security.^[3]
