Sergei Shamba has been in politics since the age of 24, and has been heavily involved in Abkhazia's struggle for independence. Before becoming foreign minister, he served as head of the Council of Ministers of Abkhazia and as head of the Abkhazian People's Front, a leading opposition movement around the time of the Georgian-Abkhaz war.

Shamba became Minister for Foreign Affairs on 7 May 1997, succeeding Konstantin Ozgan.Throughout his time as foreign minister, it has often fell to Shamba to defend Abkhazia's separation from Georgia in the international media. He has been a strong supporter of Abkhazian independence, and has flatly opposed any attempts at reunification with Georgia. Though he has headed several Abkhaz delegations to United Nations-sponsored talks with Georgia, Abkhazia has failed to receive any international recognition.
