Moldova–Transnistria relations are the political and economic relations between the Republic of Moldova and Transnistria (officially the Pridnestrovian Moldavian Republic), an unrecognized state between the Dniester River and Ukraine. During the dissolution of the Soviet Union, political tensions in the Moldavian Soviet Socialist Republic led to Transnistria declaring independence from Moldova, culminating in the Transnistrian War of 1992. As part of the ceasefire agreement ending the war, a Joint Control Commission composed of Moldovan, Transnistrian, and Russian forces was established to supervise the demilitarized zone which was located in the Transnistrian region. The Joint Control Commission still supervises the zone, and negotiations to resolve the dispute are ongoing. The negotiations are supported by the Russian Federation, Ukraine, the United States, the European Union, and the Organization for Security and Co-operation in Europe (OSCE).
