In contrast to territories that were to be acquired in Europe itself (specifically European Russia), these areas were not envisaged as targets for extensive German population settlement. The establishment of a vast colonial empire was to serve primarily economic purposes, for it would provide Germany with most natural resources that it would not be able to find in its continental possessions, as well as an additional nearly unlimited supply of labor. Racialist policies would nevertheless be strictly enforced on all inhabitants (meaning segregation of Europeans and blacks and punishing of interracial relationships) to maintain "Aryan" purity.
