To the extent that the United States has jurisdiction to prohibit such activity by such person, no United States person and no foreign person may engage in any prohibited activity.

Neither the Board of Governors of the Federal Reserve System nor the Federal Reserve Bank of New York may designate, or permit the continuation of any prior designation of, the person as a primary dealer in United States Government debt instruments.
If the President makes a determination under subsection (c) with respect to a foreign person, the Congress urges the President to initiate consultations immediately with any appropriate foreign government with respect to the imposition of any sanction pursuant to this section.
In order to pursue consultations described in paragraph (1) with any government referred to in such paragraph, the President may delay, for up to 90 days, the effective date of an order under subsection (c) imposing any sanction.
Following consultations described in paragraph (1), the order issued by the President under subsection (c) imposing any sanction on a foreign person shall take effect unless the President determines, and certifies in writing to the Congress, that the government referred to in paragraph (1) has taken specific and effective actions, including the imposition of appropriate penalties, to terminate the involvement of the foreign person in any prohibited activity.
After the end of the period described in subparagraph (A), the President may delay, for up to an additional 90 days, the effective date of an order issued under subsection (b) imposing any sanction on a foreign person if the President determines, and certifies in writing to the Congress, that the appropriate foreign government is in the process of taking actions described in subparagraph (B).
The President may waive the continued application of any sanction imposed on any person pursuant to an order issued under subsection (c) if the President determines, and certifies in writing to the Congress, that the continued imposition of the sanction would have a serious adverse effect on the safety and soundness of the domestic or international financial system or on domestic or international payments systems.
If knowledge of the existence of a particular circumstance is required for an offense, such knowledge is established if a person is aware of a high probability of the existence of such circumstance, unless the person actually believes that such circumstance does not exist.
