The President may, whenever he determines such action appropriate, negotiate with representatives of foreign governments in an effort to obtain agreements limiting the export from such countries and the importation into the United States of any agricultural commodity or product manufactured therefrom or textiles or textile products, and the President is authorized to issue regulations governing the entry or withdrawal from warehouse of any such commodity, product, textiles, or textile products to carry out any such agreement. In addition, if a multilateral agreement, including but not limited to the Agreement on Textiles and Clothing referred to in section 3511(d)(4) of title 19, has been or is concluded under the authority of this section among countries accounting for a significant part of world trade in the articles with respect to which the agreement was concluded, the President may also issue, in order to carry out such agreement, regulations governing the entry or withdrawal from warehouse of the same articles which are the products of countries not parties to the agreement, or countries to which the United States does not apply the agreement. Nothing herein shall affect the authority provided under section 624 of this title.

There is hereby authorized to be appropriated for each fiscal year, beginning with the fiscal year ending June 30, 1957, the sum of $500,000,000 to enable the Secretary of Agriculture to further carry out the provisions of section 612c of this title, subject to all provisions of law relating to the expenditure of funds appropriated by such section, except that up to 50 per centum of such $500,000,000 may be devoted during any fiscal year to any one agricultural commodity or the products thereof.

Notwithstanding any other limitations as to the disposal of surplus commodities acquired through price support operations, the Commodity Credit Corporation is authorized on such terms and under such regulations as the Secretary of Agriculture may deem in the public interest, and upon application, to donate food commodities acquired through price support operations to Federal penal and correctional institutions, and to State correctional institutions for minors, other than those in which food service is provided for inmates on a fee, contract, or concession basis.
