Following the terrorist attacks of 11 September 2001, an Extraordinary European Council session is held on 21 September. The main aims of this meeting are to examine the international situation and provide impetus for EU action in the fight against terrorism. The European Council stresses the need for ‘global coordination’ and promotes an ‘interdisciplinary approach’. It approves a plan of action which includes enhancing police and judicial cooperation, developing international legal instruments, putting an end to the funding of terrorism and strengthening air security. Moreover, it insists on the need to further the common foreign and security policy (CFSP) and to swiftly implement the European security and defence policy (ESDP). The European Council highlights the negative effects that the terrorist attacks are having on the economy but envisages the forthcoming introduction of the euro as a source of stability.
