Relations with the EU/Representation at EU level
 

Estonia has been a full member of the European Committee of the Regions (CoR) since 2004. The Estonian delegation to the CoR consists of 7 full members and 7 alternate members.

The Association of Estonian Cities and Municipalities (AECM) is consulted in the nomination process of national members to the Committee of the Regions and the Congress of Local and Regional Authorities of the Council of Europe (CLRAE). This clause is written in the nomination procedures that are approved by the Minister of Public Administration.

The predecessors of AECM (the Association of Rural Municipalities of Estonia (AME) and the Association of Estonian Cities (AEC)) had a joint Brussels Office since 2005, which after the merger of the two associations in 2017 became Permanent Representation of the Association of Estonian Cities and Municipalities in Brussels.

The AECM is a member of the United Cities and Local Governments (UGCL), the Council of European Municipalities and Regions (CEMR), the Baltic Sea States Sub-Regional Cooperation (BSSSC), the Conference of Peripheral Maritime Regions (CPMR) and the Congress of Local and Regional Authorities of the Council of Europe (CLRAE).

The Association co-operates with many international organisations, networks and movements such as the Union of the Baltic Cities (UBC), the International Council for Local Environmental Initiatives (ICLEI), the Baltic Local Agenda 21 Forum (BLA21F), and the World Health Organisation's (WHO) Healthy Cities Project.
