In this article the author examines in detail the bilateral relations between Spain and Brazil during the presidency of Jair Bolsonaro. In addition, the subject of this article is the opposition of EU governments to the environmental policies of the South American country and the disastrous policies of the Brazilian authorities in the fight against the COVID-19 pandemic. President Bolsonaro’s negligence of climate change and Amazon deforestation has prompted European governments to openly oppose the ratification of the Mercosur – EU Free Trade Agreement, which was signed in 2019 after 20 years of negotiations. In May 2016, the parties agreed on reciprocal terms, resulting in signing of the agreement. It also included the exchange of goods and services, essential investments and public procurements. All this was done in the context of a global policy of protectionism amid a weakening role of the WTO as a supporter of the trade liberalization process. Despite its success, countries such as France, Austria and the Netherlands stand against the Mercosur – EU trade deal, which can halt its ratification. The Spanish government, on the contrary, is lobbying for ratification of the agreement. Madrid, interested in benefiting from the Bolsonaro government’s liberal economic policies, maintains strong ties with its South American partner. The author analyzes the transformation of Spain from a relatively irrelevant partner of Brazil in the 20th century to one of the main investors directing significant resources to the Brazilian economy. We also assess the results and challenges of the Brazil – Spain strategic partnership in a broader context of the Brazil – EU relations.
