During much of the interwar period, Italians held most of the technical jobs in the Albanian economy. Albania had four ports: Durrës, Shëngjin, Vlorë, and Sarandë. Albania's main exports were petroleum, animal skins, cheese, livestock, and eggs. Primary imports were grain and other foodstuffs, metal products, and machinery. In 1939, the value of Albania's imports was four times that of its exports. About seventy percent of Albania's exports went to Italy. Italian factories furnished about forty percent of Albania's imports, and the Italian government paid for the rest.
