Traditionally, relations between Guyana and Brazil have been good. Brazil has provided small amounts of military assistance to Guyana in the form of jungle warfare training and logistical matériel. Brazil's military assistance to Guyana has been contingent on Guyana's refusal of any military aid fromÍÍÍÍ Cuba. In 1975 United States allegations that Guyana was allowing Cuban troops en route to the Angolan civil war to refuel in Guyana made the Brazilian government nervous, and it briefly undertook military maneuvers on its border with Guyana.

In the 1960s, both governments were anxious to complete a highway that would link the Brazilian city of Manaus to Georgetown. Completion of the highway would afford Brazil easy access to an Atlantic port from its northernmost states, and Guyana would gain direct access to Brazilian markets. In 1971 Brazil offered Guyana technical assistance to complete the Guyanese portion from Lethem to Georgetown. The offer was refused, however, and the road was not completed until the early 1990s.
