22 U.S. Code § 8543 - Destinations of Diversion Concern
The President shall designate a country as a Destination of Diversion Concern if the President determines that the government of the country allows substantial diversion of goods, services, or technologies described in section 8542(b) of this title through the country to Iranian end-users or Iranian intermediaries.
Not later than 45 days after submitting a report required by subsection (b) with respect to a country designated as a Destination of Diversion Concern under subsection (a), the President shall require a license under the Export Administration Regulations or the International Traffic in Arms Regulations (whichever is applicable) to export to that country a good, service, or technology on the list required under subsection (b)(2), with the presumption that any application for such a license will be denied.
The designation of a country as a Destination of Diversion Concern under subsection (a) shall terminate on the date on which the President determines, and certifies to the appropriate congressional committees, that the country has adequately strengthened the export control system of the country to prevent the diversion of goods, services, and technologies described in section 8542(b) of this title to Iranian end-users or Iranian intermediaries.
For termination of section, see section 8551(a) of this title.
