Additionally, the Group works to help allocate seats on United Nations bodies by nominating candidates from the region.

[3][4] Prior to the creation of the Regional Groups in 1964, the United Nations Security Council had an Eastern European and Asian Seat, that was occupied between 1946 and 1964 by countries from Eastern Europe (including Greece and Turkey), as well as by members of the modern Western European and Others and Asia-Pacific Groups.

Since its creation, the Group has changed significantly due to the dissolution of various members: the Soviet Union in 1991, Yugoslavia between 1991-2006 and Czechoslovakia in 1993.

It is also eligible for having its nationals elected as President of the United Nations General Assembly in years ending with 2 and 7; most recently, Miroslav Lajčák of Slovakia was elected to this position in 2017 and was the office holder of the Sixty-seventh session.

The Eastern European Group holds two seats on the Security Council, 1 non-permanent and 1 permanent.
