The conference aims at analysing the perspective by which both national and Community laws are dealing with the monitoring of cash flows and business activities as the key domains to develop an efficient way to combat the criminal and terrorist organisations operating in their territory. Indeed, it will be necessary to pay particular attention both to the phenomena that underlie the use of capital to conceal the illegal nature of a flow of funds and to the phenomena where wealth is directed to illegal businesses in order to support them. Moreover, as recommended by international organisations (FATF, IMF), the enhanced review procedures of Politically exposed persons’ cash flows will be discussed. The study will involve not only scholars but agents of financial institutions and of the supervisory authorities on which, usually, national governments rely for the monitoring of transactions and activities of economic operator and notify anomalies, if present.
