What changes did Mobuto Sese Seko make in the Congo?

Through his press contacts, Mobutu met the Congolese nationalist leader Patrice Lumumba, whose Congolese National Movement he joined soon after it was launched in 1958. In 1960 Mobutu represented Lumumba at the Brussels Round Table Conference on Congo independence until the release of Lumumba, who had been jailed for his nationalist activities in the Congo. During the conference, Mobutu supported Lumumba’s proposals (which were adopted) for a strongly centralized state for the independent Congo.
