On 29 February 1976, the Angolan President Agostinho Neto and Zairian President Mobuto Sese Seko met in Brazzaville to sign a non-aggression pact which was meant to see the end of Angola's support for Katangese rebels in their country while the Zairians promised to expel both the FNLA and UNITA from bases in Zaire but the deal did not hold and the Shaba I invasion would occur in March 1977. The Shaba II invasion of the Zairian Shaba Province in May 1978, by separatists based in eastern Angola, was the beginning of the end for the FNLA based in Zaire. The Angolan President Neto and Zairian President Mobuto Sese Seko would meet again in Brazzaville during June 1978 where a reconciliation pact was signed between the two countries. The result of this pact saw Holden Roberto exiled to Gabon by the Zairian President in November 1979 while he was in France for medical treatment. Elements of the FNLA would continue the fight after Roberto left, now called the FNLA-COMIRA (Angolan Military Resistance Committee) but ceased to exist by 1983.
