These states provided asylum for exiled South African political activists and allowed the African National Congress (ANC) and the Pan Africanist Congress (PAC) to set up headquarters within their borders.[citation needed] The ANC was declared as the official representative of the South African People by the United Nations and the Organization of African Unity whilst its headquarters was officially in Lusaka. Thousands of South African youth traveled to these states to receive training in sabotage and guerrilla warfare.[citation needed] The Frontline States suffered greatly for their opposition and became the target of South Africa's policy of regional destabilization; South Africa launched military incursions in Botswana, Zambia, Zimbabwe and Mozambique and supported rebel groups seeking to topple the regimes in Angola (UNITA) and Mozambique (RENAMO).[5]
