The Parliamentary Assembly of the Black Sea Economic Cooperation meets in ordinary session twice a year, usually in the last decade of June and in the first decade of December, by rotation in each member country.

The spring and autumn sessions are the main activity of the PABSEC. Each Plenary Session of the General Assembly provides a forum for vigorous discussion and debate as well as assessment of BSEC activities and votes on the adoption of reports and specific recommendations, declarations and decisions by absolute majority of the votes cast. These documents are transmitted to the BSEC Meetings of the Ministers of Foreign Affairs, the national parliaments and governments of the member countries and international organizations. Traditionally, the President of the host country, the Speakers of the eleven National Parliaments and the Chairman-in-Office of the BSEC are invited to address the PABSEC General Assembly.
