During Angola's civil war, Cuban forces fought alongside the Marxist–Leninist People's Movement for the Liberation of Angola (MPLA) government; against the Western-backed National Union for the Total Independence of Angola (UNITA) and National Liberation Front of Angola (FNLA) guerrillas who were aided by the South-African army. The present day outcome of the war resulted in the MPLA changing from a Marxist–Leninist party to a multi-party democratic system based on neoliberal principles (the MPLA also dropped the "Labour Party" extension to its name as a clear sign of dropping their communist aspirations). From an economic standpoint, Cuba has lost its preferred status among Angolans and South Africa has become the biggest single investor and trading partner with Angola (outside oil sales)
