Moldova's top negotiator in resolving the three-decade-old dispute with its pro-Russian Transdniester separatist enclave on January 28 ruled out any role for Moscow in finding a solution as long as it was engaged in its war in Ukraine. Deputy Prime Minister Oleg Serebrian made his comments on national radio as Moldova's pro-European government pressed ahead with its drive to secure EU membership. Serebrian said the 5+2 Transdniester negotiating process in place for 20 years -- which included Russia and Ukraine as well as the United States and EU as observers -- could serve no purpose as long as Moscow pursued its invasion.
