After USSR breakdown, tensions between Moldova and the unrecognized state of Dniester river left bank escalated into a military conflict that started in March 1992 and was concluded by a ceasefire in July 1992. As part of that agreement, a three-party (Russia, Moldova, Transnistria) Joint Control Commission supervises the security arrangements in the demilitarized zone, comprising twenty localities on both sides of the river. Although the ceasefire has held, the territory's political status remains unresolved: Transnistria is an unrecognized but independent presidential republic with its own government, parliament, military, police, postal system, and currency. Its authorities have adopted a constitution, flag, national anthem, and coat of arms.
