The German industrial war potential was to be destroyed by the destruction or control of all industries with military potential. To that end, all civilian shipyards and aircraft factories were to be dismantled or otherwise destroyed. All production capacity associated with war potential, such as metal, chemicals, or machinery factories, were to be reduced to a minimum level, which would later be determined by the Allied Control Commission. The manufacturing capacity thus made "surplus" was to be dismantled as reparations or otherwise destroyed. All research and international trade were to be controlled. The economy was to be decentralised by decartelisation and reorganised, with the primary emphasis on agriculture and peaceful domestic industries. In early 1946, an agreement was reached on the details of the latter in which Germany was to be converted into having an agricultural and light industrial economy. German exports were to be coal, beer, toys, textiles, etc., which would take the place of the heavy industrial products that had been most of Germany's prewar exports. France, having been excluded from the conference, resisted implementing the Potsdam agreements within its occupation zone. In particular, the French refused to resettle any Germans expelled from the east. Moreover, the French did not accept any obligation to abide by the Potsdam agreements in the proceedings of the Allied Control Council. In particular, it reserved the right to block any proposals to establish common policies and institutions across Germany as a whole and anything that could lead to the eventual emergence of a unified German government. Austria The Soviet Union proposed for the authority of Karl Renner's provisional government to be extended to all of Austria. The Allies agreed to examine the proposal after British and American forces entered Vienna. Poland A Provisional Government of National Unity, created by the Soviets and known as the Lublin Poles, was to be recognized by all three powers. The Big Three's recognition of the Soviet-controlled government effectively meant the end of recognition of the London-based Polish government-in-exile. The British and the Americans governments took measures for the Polish Provisional Government to own property in the territories of Poland and to have all the legal rights to the property so that no other government could have it. Poles serving in the British Army would be free to return to Communist Poland but with no guarantee of their security upon their return. All Poles who returned to
