Sec. 104. Infrastructure.— (a) The President is authorized to make contributions to infrastructure programs of the North Atlantic Treaty Organization, in accordance with agreements already made between the member nations, out of funds made available pursuant to this section, or section 103, or chapter IX of the Supplemental Appropriation Act, 1953, of amounts totaling not more than $780,000,000, less amounts already contributed for such purpose. There is hereby authorized to be appropriated to the President for such purpose, in installments prior to June 30, 1958, not to exceed $321,000,000, to remain available until expended. Such contributions by the United States shall not exceed its proportionate share, as heretofore agreed upon, of the expenses of such programs. (b) When the President determines that it is in the interest of the security of the United States to participate in programs for the acquisition or construction of facilities in foreign nations for collective defense other than programs of the North Atlantic Treaty organization, he may use for such purpose funds made available under section 103 or local currencies made available under section 402 in amounts totaling not more than $50,000,000. (c) Notwithstanding section 501 of this Act, no funds other than those referred to in subsections (a) and (b) of this section may be expended for the purposes of this section. No funds shall be expended under this section for rental or purchase of land or for payment of taxes.
