UN Security Council Resolution 1373 establishes measures to prevent and suppress the financing of terrorism. The Financial Action Task Force (FATF) endorses this resolution and oversees its implementation. A document of best practices, supported by GIZ and CTED, has been developed to assist countries in implementing these measures. Data were collected from various sources, including surveys of GAFILAT members. The document focuses on key aspects such as national designation procedures and international cooperation, offering best practices for their implementation.
