The international environment has changed dramatically during the last few years, and many events have influenced the military, economic, social and political dimensions of the entire world. The wars in Syria and Ukraine, the refugee crisis, the rise of terrorist organizations in Europe, Brexit, Russia's interference in US domestic elections and, last but not least, Donald Trump's election in USA are some of the events that have shaped the new international stage. The economy is the main pillar of the EU's development and the economic security is one aspect that needs immediate attention from the EU's leadership. The challenges to the EU's economic security are more present than ever and they are not only external but also internal. The paper aims to analyze the relationship between the recent changes of the international environment and EU's economic security and the perspectives of EU's economic security facing the new challenges and opportunities.
