The European Commission and the European Central Bank are working together to protect euro notes and coins in close cooperation with Europol and Interpol. See the 2015 Commission annual report on the Pericles 2020' programme for the protection of the euro against counterfeiting. For general formation on how the EU is working together to protect euro banknotes and coins from being counterfeited, see this video.
The EU works to establish a close economic and political dialogue with its neighbouring countries and also offers emergency loans and grants in difficult times. This new video episode of "European Economy Explained" shows how macro-financial assistance is arranged.
