Multilateral arms embargoes
UN arms embargoes are imposed by resolutions adopted under the authority of Chapter VII, Article 41, of the United Nations Charter by at least 9 of the 15 members of the United Nations Security Council (UNSC); with no vetoes by any of the five permanent members (P5). There are two types of UNSC arms embargo: voluntary and mandatory. UN members are legally obliged to enforce mandatory arms embargoes, having pledged in Chapter I, Article 2.5, of the UN Charter to 'refrain from giving assistance to any state against which the United Nations is taking preventive or enforcement action'.
European Union (EU) arms embargoes are imposed by Common Positions adopted unanimously by the Council of the EU in the framework of the EU Common Foreign and Security Policy (CFSP). Member States are legally bound to adapt their national policies at once to these Common Positions, without having to implement changes in national legislation. The Council has made it a habit to translate each mandatory UN embargo into a Common Position, making EU-wide implementation more systematic and timely. Other EU arms embargoes implement UN embargoes but with additional EU specific requirements. Finally the EU imposes arms embargoes that have no UN counterpart.
Other regional and sub-regional organisations, such as the OSCE or the Economic Community of West African States (ECOWAS), have imposed multilateral arms embargoes. Enter the SIPRI Arms Embargoes Database
