And, oddly, Croatia suggests that Greece enter into arbitration as Croatia agreed to with Slovenia. Maybe Croatia is much better protected than Cyprus was in arbitration in 2004, but since Croatia is outside the EU and Slovenia is in, I expect that the Croatian PM will be eating his words as the arbitrators (I assume the arbitration is binding) tilt heavily toward the Slovenian side.

From what I can tell, international arbitrators are not wholesome and fair all the time. Croatia may be in for a rude awakening.
