The European Union is the abbreviation of the European Union, which is the same body of politics and economy. At first, there were only six founding members, namely Germany, France, Italy, the Netherlands, Belgium and Luxembourg. Now it has 27 member countries and 24 official languages, and its headquarters is in Brussels, Belgium. At present, the European Union is one of the most economically developed regions in the world, and the gradual deepening of economic integration has promoted the further economic prosperity of this region.

Among the 27 member States of the European Union, Luxembourg (Germany, France, etc. ), Belgium (Netherlands, France, etc. ), Austria (German) and Cyprus (Greek) do not have their own independent languages, but English is still retained as one of the official languages of the European Union. Moreover, all official documents, publications, important conferences and official websites of the European Union must use these 24 languages at the same time.

The birth of the European Union realized the free circulation of goods, services, people and capital in Europe and accelerated the economic growth in Europe. In foreign trade, the United States, China, Russian and Swiss are the main trading partners. Of course, the EU is also the largest export market and aid provider for the least developed countries in the world, and an advocate and main leading force of the multilateral trading system.

Generally speaking, the EU is a large international organization for regional economic cooperation in Europe. Member States also handed over some national sovereignty (mainly economic aspects, such as currency, financial policy, internal market and foreign trade) to the organization.
