Following the approval of Hitler of the Operation Barbarossa plan, Hitler instructed Göring to develop a plan for the future exploitation of conquered territory in the East. Under Göring's leadership, a plan known as Oldenburg was created to include the seizing for the service of the Reich all stocks of raw materials and large industrial enterprises in the territory between the Vistula and the Urals. According to this plan the most valuable manufacturing equipment was to be sent to the Reich and that which was not sent to Germany would be destroyed. The European part of the Soviet Union would be economically decentralized and be turned into an agricultural appendage of Germany.
