The United Arab Emirates (UAE) has become one of the most aggressive external actors in African conflicts, from Ethiopia, Libya and Somalia to Sudan. The leadership in Abu Dhabi obstinately denies its support for belligerents, yet it has maintained it even during the US-Israeli war against Iran – despite the serious repercussions for the UAE. Its role impedes efforts at conflict resolution and exacerbates humanitarian crises and regional instability. It undermines Europe’s interest in reliable trade routes, the prevention of forced displacement and regional integration. Germany and its European partners should accord much greater weight to the UAE’s destabilising actions in their bilateral relations, criticise them more explicitly and consider sanctions. The context of the war with Iran, as well as tensions between the UAE and Saudi Arabia, offers an opening for a change in policy in Abu Dhabi.
