Passage: The ECA's official mission statement was to give a boost to the European economy: to promote European production, to bolster European currency, and to facilitate international trade, especially with the United States, whose economic interest required Europe to become wealthy enough to import US goods. Another unofficial goal of ECA (and of the Marshall Plan) was the containment of growing Soviet influence in Europe, evident especially in the growing strength of communist parties in Czechoslovakia, France, and Italy.
