It's not about following accords and procedures. If it were, Romania and Bulgaria would have taken this to court and clarified it a long time ago.

I don't know what Bulgaria's deal is with Austria but in Romania's case there are unfinished backroom deals regarding OMV and petrol concessions in Romania.

This latest round of hurdles was raised by Austria in response to Romania being unwilling to cut OMV priority access to the Black Sea oil extraction rigs currently under development.

It has nothing to do with immigrants and all the other jazz, that's just official posturing for public benefit. Both parties claim one inflammatory issue out in the open while negotiating the real deals in the background.
