The office was created by unifying the existing European Commission Liaison Office and the Office of the EU Special Representative (EUSR), each of which had a different representative.
Söz konusu ofis, her biri farklı bir temsilciye sahip mevcut Avrupa Komisyonu İrtibat Bürosu ve AB Özel Temsilciler Dairesi (EUSR) birleştirilerek kuruldu.
