On 23 August, dos Santos complained that the U.S. and South African governments continued to fund UNITA, warning such activity endangered the already fragile ceasefire. The next day Savimbi announced UNITA would no longer abide by the ceasefire, citing Kaunda's insistence that Savimbi leave the country and UNITA disband. The MPLA government responded to Savimbi's statement by moving troops from Cuito Cuanavale, under MPLA control, to UNITA-occupied Mavinga. The ceasefire broke down with dos Santos and the U.S. government blaming each other for the resumption in armed conflict.
