Brazil continued to try to remain neutral to the United States and Germany because it was trying to make sure it could continue to be a place of interest for both opposing countries. Brazil attended continental meetings in Buenos Aires, Argentina (1936); Lima, Peru (1938); and Havana, Cuba (1940) that obligated them to agree to defend any part of the Americas if they were to be attacked. Eventually, Brazil decided to stop trading with Germany once Germany started attacking offshore trading ships resulting in Germany declaring a blockade against the Americas in the Atlantic Ocean. Furthermore, Germany also ensured that they would be attacking the Americas soon.
