The "European Union" is an economic and political joining between 27 European countries. It ensures the free movement of people, goods, services, and capital in the internal market, as well as the maintenance of common policies. It's commonly referred to as the acronym "EU." Ex: The EU recently placed a ban on coal imports from Russia. Ex: Biometric passports are likely to be made compulsory by the European Union.
