The Serb National Council has been continuously working on the return of the exiled refugees and growth of under-developed regions since its foundation. The Council has participated in realization of projects regarding the fulfillment of necessary conditions for the return of refugees, reconstruction of housing units, repair and development of necessary infrastructure, and more recently on economic growth and sustainability of regions where members of Serbian community live (with special emphasis on Areas of Special State Concern - ASSC).

Returnees face devastated infrastructure (roads, water supply and sewage systems), lack of expert help, insufficient insight in the work of institutions which encourage and develop agricultural and economic activities and lack of funds for the development of current and new programs.

The Center for development and investitions works to stimulate economic development and create an entrepreneurial climate and promote the potential of local self-government units in returnee environments and in other areas where Serbs live.
