(b) Information Eligible for Exemption.—For the purposes of this section, information is sensitive information of a foreign government only if the national security official concerned makes each of the following determinations with respect to the information:

(1) That the information was provided by, otherwise made available by, or produced in cooperation with, a foreign government or international organization.

(2) That the foreign government or international organization is withholding the information from public disclosure (relying for that determination on the written representation of the foreign government or international organization to that effect).

(c) Information of Other Agencies.—If the national security official concerned provides to the head of another agency sensitive information of a foreign government, as determined by that national security official under subsection (b), and informs the head of the other agency of that determination, then the head of the other agency shall withhold the information from any public disclosure unless that national security official specifically authorizes the disclosure.

(d) Limitations.—(1) If a request for disclosure covers any sensitive information of a foreign government (as described in subsection (b)) that came into the possession or under the control of the United States Government before October 30, 2000, and more than 25 years before the request is received by an agency, the information may be withheld only as set forth in paragraph (3).

(ii) if there are more than one such foreign governments or international organizations, the latest date so specified by any of them.

(C) If no date is applicable under subparagraph (B) to a request referred to in subparagraph (A) and the information referred to in that subparagraph came into possession or under the control of the United States more than 10 years before the date on which the request is received by an agency, the information may be withheld under this section only as set forth in paragraph (3).

(3) Information referred to in paragraph (1) or (2)(C) may be withheld under this section in the case of a request for disclosure only if, upon the notification of each foreign government and international organization concerned in accordance with the regulations prescribed under subsection (g)(2), any such government or organization requests in writing that the information not be disclosed for an additional period stated in the request of that government or organization. After the national security official concerned considers the request of the foreign government or international organization, the official shall designate a later date as the date after which the information is not to be withheld under this section. The later date may be extended in accordance with a later request of any such foreign government or international organization under this paragraph.

(e) Information Protected Under Other Authority.—This section does not apply to information or matters that are specifically required in the interest of national defense or foreign policy to be protected against unauthorized disclosure under criteria established by an Executive order and are classified, properly, at the confidential, secret, or top secret level pursuant to such Executive order.
