The euro is a world currency. It is the official currency of 19 European States, and according to the June 2018 report by the European Central Bank (ECB) on the international role of the euro, it is by far, ahead of the pound, the yen and the renminbi, the world's second most important currency. The euro turned twenty on January 1st 2019. The strengthening of the single currency will be achieved via its increased use by the EU's economic and trade partners. Promoting the internationalisation of the euro would also strengthen the influence and security of Europe. In virtue of this it must be a diplomatic goal of the institutions and the Member States.
