Whenever the President determines it to be in furtherance of the purposes of this chapter, the head of any agency of the United States Government is authorized to detail or assign any officer or employee of his agency to any office or position with any foreign government or foreign government agency, where acceptance of such office or position does not involve the taking of an oath of allegiance to another government or the acceptance of compensation or other benefits from any foreign country by such officer or employee.

Whenever the President determines it to be consistent with and in furtherance of the purposes of this chapter, the head of any agency of the United States Government is authorized to detail, assign, or otherwise make available to any international organization any officer or employee of his agency to serve with, or as a member of, the international staff of such organization, or to render any technical, scientific, or professional advice or service to, or in cooperation with, such organization.

None of the funds made available pursuant to the provisions of this chapter shall be used to carry out any provision of this chapter in any country or with respect to any project or activity, after the expiration of the thirty-five-day period which begins on the date the Government Accountability Office or any committee of the Congress charged with considering legislation, appropriations or expenditures under this chapter, has delivered to the office of the head of any agency carrying out such provision, a written request that it be furnished any document, paper, communication, audit, review, finding, recommendation, report, or other material in its custody or control relating to the administration of such provision in such country or with respect to such project or activity, unless and until there has been furnished to the Government Accountability Office, or to such committee, as the case may be, (1) the document, paper, communication, audit, review, finding, recommendation, report, or other material so requested, or (2) a certification by the President that he has forbidden the furnishing thereof pursuant to request and his reason for so doing.

All information contained in any report transmitted under this chapter shall be public information. However, in the case of any item of information to be included in any such report that the President, on an extraordinary basis, determines is clearly detrimental to the security of the United States, he shall explain in a supplemental report why publication of each specific item would be detrimental to the security of the United States. A supplemental report shall be transmitted to the Congress at the time the report is transmitted.

Within 60 days after receiving information which substantiates that officials of a foreign country receiving international security assistance have (1) received illegal or otherwise improper payments from a United States corporation in return for a contract to purchase defense articles or services from such corporation, or (2) extorted, or attempted to extort, money or other things of value in return for actions by officials of that country that permit a United States citizen or corporation to conduct business in that country, the President shall submit to Congress a report outlining the circumstances of such payment or extortion. The report shall contain a recommendation from the President as to whether the United States should continue a security assistance program for that country.

For the purpose of facilitating implementation of section 55305 of title 46, funds made available for the purposes of part I of subchapter I of this chapter or for purposes of part IV of subchapter II of this chapter may be used to make grants to recipients to pay all or any portion of such differential as is determined by the Secretary of Commerce to exist between United States and foreign-flag vessel charter or freight rates. Grants made under this section shall be paid with United States-owned foreign currencies wherever feasible.
