The Ukrainian crisis has entrapped the German government into a diplomatic dilemma over the issue of European security. On the one hand，Germany still regards the NATO as the guarantee of European security and the most powerful support to its policies on security and defense. On the other hand，through historical and practical experience，Germany realizes that it is unlikely to achieve a real security in Europe without proper handling of Russia. Currently，the Ukrainian crisis is being escalated even further as the Ukraine’s parliament passed an act to renounce its previous non-aligned status. This paper elaborates the efforts made by the German government to defuse the Ukrainian crisis with focus of analysis on the following points：the principled stand of the German government in handling the Ukrainian crisis，Germany’s domestic divergences on the crisis as well as the Germany’s policy towards Russia，the causes of these divergences，and the relevance between the framework of negotiation for the Minsk Peace Deal and the Charter of Paris for a new Europe. <<
