Greece was a founding member of the Organisation for Economic Co-operation and Development (OECD) and the Organization of the Black Sea Economic Cooperation (BSEC). In 1979 the accession of the country in the European Communities and the single market was signed, and the process was completed in 1982. Greece was accepted into the Economic and Monetary Union of the European Union on 19 June 2000, and in January 2001 adopted the Euro as its currency, replacing the Greek drachma at an exchange rate of 340.75 drachma to the Euro. Greece is also a member of the International Monetary Fund and the World Trade Organization, and is ranked 24th on the KOF Globalization Index for 2013.

Transportation:
Since the 1980s, the road and rail network of Greece has been significantly modernised. Important works include the A2 (Egnatia Odos) motorway, that connects northwestern Greece (Igoumenitsa) with northern Greece (Thessaloniki) and northeastern Greece (Kipoi); the Rio–Antirrio bridge, the longest suspension cable bridge in Europe (2,250 m (7,382 ft) long), connecting the Peloponnese (Rio, 7 km (4 mi) from Patras) with Aetolia-Akarnania (Antirrio) in western Greece.
Also completed are the A5 (Ionia Odos) motorway that connects northwestern Greece (Ioannina) with western Greece (Antirrio); the last sections of the A1 motorway, connecting Athens to Thessaloniki and Evzonoi in northern Greece; as well as the A8 motorway (part of the Olympia Odos) in Peloponnese, connecting Athens to Patras. The remaining section of Olympia Odos, connecting Patras with Pyrgos, is under planning.
Other important projects that are currently underway, include the construction of the Thessaloniki Metro.
The Athens Metropolitan Area in particular is served by some of the most modern and efficient transport infrastructure in Europe, such as the Athens International Airport, the privately run A6 (Attiki Odos) motorway network and the expanded Athens Metro system.
Most of the Greek islands and many main cities of Greece are connected by air mainly from the two major Greek airlines, Olympic Air and Aegean Airlines. Maritime connections have been improved with modern high-speed craft, including hydrofoils and catamarans.
Railway connections play a somewhat lesser role in Greece than in many other European countries, but they too have also been expanded, with new suburban/commuter rail connections, serviced by Proastiakos around Athens, towards its airport, Kiato and Chalkida; around Thessaloniki, towards the cities of Larissa and Edessa; and around Patras. A modern intercity rail connection between Athens and Thessaloniki has also been established, while an upgrade to double lines in many parts of the 2,500 km (1,600 mi) network is underway; along with a new double track, standard gauge railway between Athens and Patras (replacing the old metre-gauge Piraeus–Patras railway) which is currently under construction and opening in stages. International railway lines connect Greek cities with the rest of Europe, the Balkans and Turkey.
Flag of Greece:
The national flag of Greece, popularly referred to as the “blue and white” or the “sky blue and white”, is officially recognized by Greece as one of its national symbols and has nine equal horizontal stripes of blue alternating with white. There is a blue canton in the upper hoist-side corner bearing a white cross; the cross symbolizes Eastern Orthodox Christianity, the established religion of the Greek people of Greece and Cyprus. The blazon of the flag is Azure, four bars Argent; on a canton of the field a Greek cross throughout of the second. The official flag ratio is 2:3. The shade of blue used in the flag has varied throughout its history, from light blue to dark blue, the latter being increasingly used since the late 1960s. It was officially adopted by the First National Assembly at Epidaurus on 13 January 1822.
