Moldova declared independence on August 27, 1991 as part of the dissolution of the Soviet Union. The current Constitution of Moldova was adopted in 1994. A strip of Moldovan territory on the east bank of the river Dniester has been under the de facto control of the breakaway government of Transnistria since 1990.
Due to a decrease in industrial and agricultural output following the dissolution of the Soviet Union, the service sector has grown to dominate Moldova's economy and currently composes over 60% of the nation's GDP. However, Moldova remains the poorest country in Europe.
Moldova is a parliamentary republic with a president as head of state and a prime minister as head of government. It is a member state of the United Nations, the Council of Europe, the World Trade Organization (WTO), the Organization for Security and Cooperation in Europe (OSCE), the GUAM Organization for Democracy and Economic Development, the Commonwealth of Independent States (CIS) and the Organization of the Black Sea Economic Cooperation (BSEC) and aspires to join the European Union.
