Signed on March 25, 1957, the Treaties of Rome marked the beginning of Europe’s role as a major economic force. Today, 50 years later, the European Union (EU) –with its 27 member states – is the world’s biggest economic zone. As one of the EU’s major economic sectors, the retail industry plays a key role. The METRO Group, with its strong European roots, regards the continent of Europe as the most important market worldwide.
