The SECI Network includes the regional cooperation mechanisms emerged by its own activity, its immediate strategic partners and supporting institutions as much as its cooperation and coordination partners of regional, European and global entities.

In the first instance SECI has an intrinsic relation with already self-statutory bodies such as the Business Advisory Council for SEE, SECI PRO and the SECI Regional Centre for Combating Transborder Crime. Further on, its network includes its partner and supporting institutions such as the UN ECE, the OSCE and the Stability Pact for SEE, i.e. today's Regional Cooperation Council. From a wider cooperation perspective SECI can be proud of a close cooperation with a wide range of regional, European and global policy making actors such as CEI, BSEC, AII, SEECP, Regional and National Chambers of Commerce and Industry and International finance institutions and Banks such as the EBRD, EIB, the World Bank and others. More information on these and other members of the SECI network are available within the SECI Affiliates, SECI Partners and SECI Collaborators sub-sections.
