The purpose of the present chapter is to examine UN Security Council and EU financial targeted sanctions against suspected terrorists and, secondarily, the role of intelligence cooperation in implementing these. The term “targeted sanctions” is commonly used for coercive measures directed against an individual or a corporate entity (such as a firm or political party).1 Targeted financial sanctions have evolved out of trade and economic embargoes which in turn have been either complements to military means in conflicts or as alternatives to these. Targeted sanctions take different forms, the most common being the freezing of financial assets, the suspension of credits and aid, the denial and limitation of access to foreign financial markets, trade embargoes on arms and luxury goods, flight bans, and the denial of international travel, visas and educational opportunities. When sanctions are targeted on individuals, this is primarily done by means of a “blacklist”. This entails identifying a target and then creating an obligation not to deal with the target in some way depending on the modality chosen for the sanction (trading with the target in general or in specific goods and services, making available or holding economic assets for the target etc.).2
