On March 8, 2019, FinCEN released an advisory on the FATF-identified jurisdictions with AML/CFT deficiencies. This advisory, known as FIN-2019-A001, relays information to US financial institutions regarding countries the Financial Action Task Force (FATF) has identified as having deficiencies.
FATF is an intergovernmental body comprised of 37 nations that work together to create uniform anti-money laundering standards. When countries don’t meet their standards, FATF communicates deficient countries to the FinCEN, who then provides communication to financial institutions.
This current advisory added Cambodia to the sanctions II list due to identified deficiencies. All other countries currently on the list - such as Sanction I countries of Iran (requiring enhanced due diligence) and the Democratic People’s Republic of Korea (which requires countermeasures) and Sanction II countries The Bahamas, Botswana, Ethiopia, Ghana, Pakistan, Serbia, Sri Lanka, Syria, Trinidad & Tobago, Tunisia, and Yemen - were unchanged.
