In the four and a half years ending December 31, 1958, the United States exported close to $6 billion of surplus agricultural commodities under various foreign disposal programs, the most important being the Agricultural Trade Development and Assistance Act, known commonly as P. L. 480. These P. L. 480 exports included the barter of American surpluses for imports of strategic materials, foreign relief shipments and donations and, most significantly, sales for the local currency of importers. This last type of transaction, which is without precedent in world trade, has enabled the United States to dispose of some 3.3 billion dollars' worth of surpluses in agreements made with 28 nations, and the major part of the foreign currencies generated—that is, some $2.1 billion—has been earmarked for economic development purposes in the receiving countries. Surplus disposal thus not only has become a primary means of promoting United States agricultural exports, but has acquired a major role in our foreign aid programs as well.
