Between June 5 and 6, 1963, the Guinean president Sékou Touré made an official visit to Brazzaville, the capital of the Republic of the Congo.
The visit sparked protests against the Congolese government, marking a beginning to the popular movement that would end Youlou's rule two months later.
During the visit economic cooperation between the two countries was discussed, and Touré pledged that Guinean bauxite and iron would be made available for Congolese needs for industrialization.

Following Touré's visit, Youlou sought to reach a compromise with trade unions and youth movements through power-sharing in a provisional government.
