In February, the Cuban government warned the Eastern Bloc that the Alvor Agreement would not succeed. By spring, the African National Congress and SWAPO echoed Cuba's warning.[6] Leaders of the Organization of African Unity organised a peace conference, moderated by Kenyan President Jomo Kenyatta, with the three leaders in Nakuru, Kenya, in June. The Angolan leaders issued the Nakuru Declaration on 21 June,[7] agreeing to abide by the provisions of the Alvor Agreement while they acknowledged that a mutual lack of trust had led to violence.[3]
