Transnistria War (1992)
After Moldova declared independence, its government fought Russian-backed separatists in Transnistria, a strip of land on the Dniester river. Russia's 14th Guards Army intervened on the separatist side. A July 1992 ceasefire froze the conflict and left Russian troops in place.
Moldova lost control of Transnistria, and Russian peacekeepers stayed.
The frozen conflict gave Moscow a permanent lever over Moldovan politics and energy, including the Cuciurgan power plant.
The plant still supplies much of Moldova's electricity, which is why the new Romanian line matters.
