In the wake of ever-increasing violence and atrocities in South Sudan, President Obama signed Executive Order 13664 (EO) on April 3, 2014 enabling the United States to target those responsible for the conflict in the almost three year-old country.
After South Sudan declared independence, the United States clarified that the existing U.S. embargo on Sudan did not apply to the new country. The new EO does not alter this policy as the U.S. Office of Foreign Assets Control (OFAC) has clarified that the new EO does not target the country of South Sudan.
Instead, the EO provides OFAC with new authority to designate certain persons that it determines to be "threaten[ing] the peace, stability, or security of South Sudan; commit[ing] human rights abuses against persons in South Sudan; expand[ing] or extend[ing] the conflict in South Sudan or obstruct[ing] reconciliation or peace talks or processes; or undermin[ing] democratic processes or institutions in South Sudan."
To date, OFAC has not yet sanctioned any persons under this new authority.
