International bodies, including the United Nations Office on Drugs and Crime (UNODC), have prepared model laws to assist countries to incorporate AML measures. Though countries concluded a treaty against terrorist financing in 1999, it was not until after the events of 11 September 2001 that anti-terrorism financing norms, as part of the panoply of AML measures, were diffused around the world by UNSC resolutions. While AML originally covered only property derived from crime, its measures were extended to property used to finance or carry out crimes, most notably for terrorist acts and the proliferation of weapons of mass destruction. The AML measures include the criminalization of money laundering, powers to freeze and confiscate the proceeds of crime, duties of the private sector to generate financial intelligence, the establishment of financial intelligence units (FIUs), and formal legal cooperation arrangements between states, necessary given the transnational dimension of money laundering. This was followed by AML measures against organized crime and corruption, respectively, in the 2000 UN Convention against Transnational Organized Crime (Palermo Convention), including its protocols and the 2003 UN Convention against Corruption (Merida Convention).

Beginning with the 1988 UN Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances (Vienna Convention), states agreed to establish anti-money laundering (AML) measures in their domestic law for drug-related offenses. Introduction:В The international law of money laundering is found in several United Nations (UN) crime suppression treaties, United Nations Security Council (UNSC) resolutions, and a body of soft law, some of which arguably has crystallized as customary norms.
