Angolan President Jose Eduardo dos Santos has reshuffled his cabinet, replacing his influential state minister for economic coordination.
Citing a statement from the president's office, state media say Manuel Nunes Junior was dismissed and will take a position in another government institution.
Nunes Junior's post was renamed economy minister and given to former central bank governor Abraao Pio dos Santos Gourgel. Jose de Lima Massano was named the new central bank governor.
The president's office did not give a reason for the moves.
State media also reported that Mr. dos Santos promoted an ex-general in Angola's former rebel movement, UNITA (Union for the Total Independence of Angola), to the top post in the armed forces.
Geraldo Sachipengo Nunda will take over the top military post from Francisco Pereira Furtado.
Mr. dos Santos has ruled Angola since 1979. He has repeatedly delayed presidential elections since the end of the country's civil war in 2002.
In January, Angola's parliament approved a new constitution that called for parliamentary elections to be held in 2012.
The new charter also said the president will be chosen by the party that wins parliamentary elections, virtually ensuring that Mr. dos Santos will stay in power for years to come. His MPLA party won about 80 percent of the vote in 2008 polls.
