A significant element in the EU co-operation with Eastern Africa relates to the EU’s aspirations to support democracy worldwide. The Treaty of Nice of the EU (2001) explicitly stipulated that promoting human rights and freedoms should be part of all EU development and other co-operation with developing countries. This principle gained prominence and an explicit codification in the Cotonou Agreement between the EU and the African, Caribbean and Pacific states (ACP) between 2000 and 2022. The year 2022, when a new agreement is to be signed, is a good time to look back at the application of these principles. Has the EU been able to support democracy in Eastern Africa? To this end, this chapter pays attention to both positive and negative democratisation instruments. The positive instruments like the election observation missions (EOM) appear to be the public image of EU democracy support before everything else. Economic sanctions, particularly smart sanctions and suspension of development aid, are the most important negative instruments. Together, these instruments have become an increasingly important part of the AU and EU’s attempts to prevent the erosion of democratic institutions in its Eastern African partner countries.
