If the President makes the determinations described in subsection (a)(1) with respect to a foreign person, the Congress urges the President to initiate consultations immediately with the government with primary jurisdiction over that foreign person with respect to the imposition of sanctions pursuant to this section.
In order to pursue such consultations with that government, the President may delay imposition of sanctions pursuant to this section for a period of up to 90 days. Following these consultations, the President shall impose sanctions unless the President determines and certifies to the Congress that that government has taken specific and effective actions, including appropriate penalties, to terminate the involvement of the foreign person in the activities described in subsection (a)(1). The President may delay imposition of sanctions for an additional period of up to 90 days if the President determines and certifies to the Congress that that government is in the process of taking the actions described in the preceding sentence.
The President shall report to the Congress, not later than 90 days after making a determination under subsection (a)(1), on the status of consultations with the appropriate government under this subsection, and the basis for any determination under paragraph (2) of this subsection that such government has taken specific corrective actions.
The United States Government shall not procure, or enter into any contract for the procurement of, any goods or services from any person described in subsection (a)(3).
The sanctions imposed pursuant to this section shall apply for a period of at least 12 months following the imposition of sanctions and shall cease to apply thereafter only if the President determines and certifies to the Congress that reliable information indicates that the foreign person with respect to which the determination was made under subsection (a)(1) has ceased to aid or abet any foreign government, project, or entity in its efforts to acquire chemical or biological weapons capability as described in that subsection.
The President may waive the application of any sanction imposed on any person pursuant to this section, after the end of the 12-month period beginning on the date on which that sanction was imposed on that person, if the President determines and certifies to the Congress that such waiver is important to the national security interests of the United States.
If the President decides to exercise the waiver authority provided in paragraph (1), the President shall so notify the Congress not less than 20 days before the waiver takes effect. Such notification shall include a report fully articulating the rationale and circumstances which led the President to exercise the waiver authority.
