Now Moldova.
Not all Moldavia but Transnistria wich is East side wich is under Russian ocupation, maybe.
I still don't understand. What are these regions? Has Russia done anything other than building troops on the border?
Moldavia was a region of Romania untill 1942, whem USSR occupiaed that region untill 1991 ,when Modavia became an independent country. .In 1992 Russian minority population from Transnistria East Moldavia- proclaimed independence of Transnistria .There was a "war" fighs between Moldavian army and Russian people ,in that moment 1992 Russia sent troups there and occupied Transnitria (as peace troops), today they are still there . Only Russia recognized Trasnistria independence.
