"The Marshall Plan enabled the economies of Western Europe to overcome their dollar shortage and thus to finance trade and investment. This ensured that American-style technologies could be adopted and also that free trade would benefit at the expense of protectionism. The greater integration of the Western economy was an important consequence, and the Marshall Plan led to the European Payments Union, which encouraged the ready convertibility of currency, and looked toward the establishment of the European Economic Community. Marshall Plan Aid was rejected by the Soviet Union as a form of economic imperialism. This aid certainly represented a demonstration of American strength that could serve to create links. This rejection created a new boundary line: between the areas that received such aid and those that did not."
