In 1946, the Soviet Union stopped delivering agricultural products from their sector in Eastern Germany to the more industrial western sectors and zones. In return, the American military administrator, Lucius D. Clay, ceased transferring supplies and dismantled factories from the Ruhr area to the Soviet sector. As a result of this, the Soviet Union started a public relations campaign against American policy and began to obstruct the administrative work of all four sectors.
The USA and the UK united their zones, creating Bizone, in order to advance the development of a new political order in Western Germany. Nevertheless, this was the first step that would eventually lead to the separation of Germany into East Germany and West Germany.
