European Foreign Policy Components
The Council of the European Union sets the Common Foreign and Security Policy (CFSP), which is overseen by the High Representative for the Common Foreign and Security Policy, Javier Solana, who is also the Secretary General of the Council of the European Union. The European Security and Defense Policy (ESDP) is developed "within the context of the CFSP." The ESDP saw the creation of the European Defense Agency (EDA) in 2004. Who heads it? Javier Solana is the "Head of EDA".
Do not confuse the work of the European Council* with the work of the European Commission. The Commissioner of External Relations, Benita Ferrero-Waldner, oversees the work of the Directorate-General for External Relations. Ferrero-Waldner oversees the European Neighborhood Policy, which covers these countries. For links to EU policies on Enlargement, External Trade, Development Policy, and Humanitarian Aid, see this portal.
Think of the Council and the CSFP as setting the broader policy and the Commission officials as implementing it.
* The official name is the "Council of the European Union". When the heads of states and governments meet with the president of the Council of the EU, those meetings are referred to as meetings of "the European Council," but it has no powers except as exercised through "the Council" of the EU.
