摘要
The euro is an important achievement of European integration and the construction of the European Union(EU) single market. As a primary international currency second only to the US dollar, the euro faces severe challenges in its internationalization process today. Since the second half of 2018, the EU has demonstrated an increased desire to enhance the international influence of the euro, with more expansionary actions toward this end. This is due to economic benefits and strategic interests in the transformative global context. In the future, the internationalization of the euro may reap some practical results in certain areas, but will hardly make marked progress due to realistic constraints.
