(A) A sanction described in paragraph (4) or (5) of subsection (a) or in any of subparagraphs (A) through (D) of subsection (b)(2) shall not apply to any activity pursuant to any contract or international agreement entered into before the date of the presidential determination under section 5604(a)(1) of this title unless the President determines, on a case-by-case basis, that to apply such sanction to that activity would prevent the performance of a contract or agreement that would have the effect of assisting a country in using chemical or biological weapons in violation of international law or in using lethal chemical or biological weapons against its own nationals.

(B) The same restrictions of subsection (p) of section 4605 ¹ of title 50, as that subsection is so redesignated by section 304(b) of this title, which are applicable to exports prohibited under section 4605 ¹ of title 50, shall apply to exports prohibited under subsection (a)(5) or (b)(2)(C) of this section. For purposes of this subparagraph, any contract or agreement the performance of which (as determined by the President) would have the effect of assisting a foreign government in using chemical or biological weapons in violation of international law or in using lethal chemical or biological weapons against its own nationals shall be treated as constituting a breach of the peace that poses a serious and direct threat to the strategic interest of the United States, within the meaning of subparagraph (A) of section 4605(p) ¹ of title 50.

(2) Sanctions applied to existing contracts
The sanctions described in paragraphs (1), (2), and (3) of subsection (a) shall apply to contracts, agreements, and licenses without regard to the date the contract or agreement was entered into or the license was issued (as the case may be), except that such sanctions shall not apply to any contract or agreement entered into or license issued before the date of the presidential determination under section 5604(a)(1) of this title if the President determines that the application of such sanction would be detrimental to the national security interests of the United States.
