Abstract: This document is a strategy document on development of sustainable e- Infrastructure in the Baltic States and Belarus. It is based on strategic policy documents of EU Commission, policy coordinating organizations and the best practice cases of other projects. Analysis of current situation in the Baltic States and Belarus is made and strategic development plans of each country are presented. Conclusion is made that e-Infrastructures in Baltic States and Belarus are in the different maturity stage compared to the rest of Europe. All BG-II partner countries do not have NGI organisations yet, but are planning to join EGI as eligible members and their representative organisations signed MoU to join this organization in future. This is taken into account in elaborating a long term strategy for a coherent e-Infrastructure development in Baltic States and Belarus for joining the European e-Infrastructure and ERA.
