Remember, Moldova is former Romanian territory with a larger ethnic Romanian population and there have been recent (as of late last year) talks about reunification.
Romania has stated on several occasions they will defend it if nessecary.
If the ole memory chipset is working right, they claimed Bessarabia in 39 or 40 as part of the Ribbentrop Pact. That's most of modern Moldova. I don't doubt that if they succeed in Ukraine now, Moldova is next on the menu, in a few years.
