1. Moldova has received 300 mln USD developmental aid per year (net ODA2008 - 299 mln USD, 2007 - 267 mln USD), what constitutes 4,5 % its GNI (2007 - 5,5% GNI). 2. Foreign aid is not only an effect of international solidarity of states and people or an effect of international business strategies. Foreign aid transfer results also from the need of strengthening an international security and stability. 3. Moldova is perceived as one of fragile states (FSI Index 2009: rank 54, the second category of states), not only because of the macroeconomic, social and political indica¬ tors, but also because of unresolved conflict about Pridniestrovie. 4. Strengthening Moldova's stability is included in an EU interests. (Moldova belongs to union close foreign countries; he is a member of the EU Eastern Partnership). 5. Strengthening Moldova's stability and development through transferring devel¬ opmental aid is less costly then by conducting stabilisation and peacekeeping missions or resolution escalated conflicts. 6. Such politic is characteristic of EU's policy of (wide understanding) security. Even though it is motivated by the safety of EU member states, it is called the EU solidarity policy (in Germany it is called policy for peace). 7. EC is the main donator of development assistance for Moldova (Germany is the 7th). Paper evaluates the global developmental aid (mostly EU: European Commission's and EU member states) in the context of international security and stability; it analyses the aid impact on the stabilisation of fragile states (on the example of Moldova) and tries to find out the consequences of developmental aid understood as security policy.
