South African authorities after they suspended all outgoing military exports to the NDF. Angola The Angolan government had fought against Mobutu Sésé Seko in the First Congo War because of his support for rebel UNITA in the Angolan Civil War. The Angolan government wanted to eliminate UNITA operations in southern Congo, which exchanged diamonds extracted from rebel-held Angola for foreign weapons. Angola had no confidence that a new president would be more effective than Kabila and feared that continued fighting would lead to a power vacuum that could only help UNITA. The intervention of the experienced Angolan forces was essential in deciding the outcome of both wars. Chad Kabila had originally discounted the possibility of support from Françafrique (Francophone Africa) but after a summit meeting in Libreville, Gabon, on 24 September, Chad agreed to send 2,000 troops. France had encouraged Chad to join as a means of regaining influence in a region where the French had retreated after the 1994 genocide committed against Tutsi in Rwanda. Nevertheless, Chadian intervention resulted in a fiasco. Its forces were accused of serious human rights violations and looting, virtually from their arrival in the country. They withdrew very quickly under international and national pressure and opprobrium. Sudan Unconfirmed reports in September indicated that forces of the government of Sudan were fighting rebels in Orientale Province, close to the Sudanese and Ugandan borders. However, Sudan did not establish a significant military presence inside the DRC, though it continued to offer extensive support to three Ugandan rebel groups—the Lord's Resistance Army, the Uganda National Rescue Front II and the Allied Democratic Forces—in retaliation for Ugandan support for the Sudan People's Liberation Army. 1999–2000 On 5 April 1999, tensions within the RCD about the dominance of the Banyamulenge reached a boiling point when RCD leader Ernest Wamba dia Wamba moved his base from Goma to Uganda-controlled Kisangani to head a breakaway faction known as RCD-Kisangani, which later became The Forces for Renewal. A further sign of a break occurred when President Yoweri Museveni of Uganda and Kabila signed a ceasefire accord on 18 April in Sirte, Libya, following the mediation of Libyan leader Muammar al-Gaddafi, but both the RCD and Rwanda refused to take part. On 16 May Wamba was ousted as head of the RCD in favour of a pro-Rwanda figure, Dr. Emile Ilunga. Seven days later the various factions of the RCD clashed over control
