The Office of Foreign Assets Control (OFAC) of
the US Department of the Treasury administers and enforces economic
and trade sanctions based on US foreign policy and national
security goals against foreign countries, regimes, terrorists, and
similar forces that are engaged in activities related to the
proliferation of weapons of mass destruction and other acts that
may be considered as threats to the national security, foreign
policy or economy of the United States of America
(US).
The nature of sanctions imposed by the US is two pronged, i.e.
Primary and Secondary. Primary sanctions are in the nature of asset
freezing, trade embargos, and a prohibition on US citizens and
companies from engaging with Iran. Secondary sanctions place an
embargo on third-party countries, its citizens and companies with
no nexus to the US, for dealing with sanctioned countries.
Secondary sanctions are invariably extra-territorial in nature and
raise important questions about legitimacy,
