Cuba will withdraw its troops from Angola under a four-year timetable if South Africa ends its occupation of South-West Africa, a Cuban official said Thursday.

Jorge Risquet Valdes, Cuba's delegate in Angolan peace talks, outlined his country's terms for withdrawing from Angola at a news conference.

Angola, Cuba, South Africa and the United States concluded a two-day conference Wednesday aimed at ending the Angolan civil war.

Cuban troops were sent into Angola in 1975 to defend the Marxist government against pro-Western rebels of the National Union for the Total Independence of Angola. The United States aids the rebel group.

South Africa troops also are in southern Angola to back the rebel movement and to attack Angolan bases of the South-West African People's Organization, which is fighting for independence of the South African-held territory of South-West Africa, or Namibia.
