riots of 4 January 1959 Belgian leaders became increasingly fearful of a violent political conflict emerging in the Congo. The security situation in the country deteriorated over the course of the year, especially in the Lower Congo and in Kasai, where violent clashes between Baluba and Lulua were taking place. Fearing the degeneration of the unrest into a colonial war and facing intense pressure for reform, in late 1959 the Belgian government announced that it would host a round table conference in Brussels in 1960 with the Congolese leadership to discuss the political future of the country.

The decisions of the delegates were ratified in a series of resolutions on 19 February and the conference closed the following day.

Summarising the similarities between the Loi Fondementale and the Constitution of Belgium, Raymond Scheyven, Minister-in-charge of Economic Affairs for the Congo, observed, "We have presented the Congolese with a political system similar to ours....It features communes, provincial assemblies, a bicameral system, and a political system where the head of state is irresponsible."
