Zbog njegovih kritika vlade Kosorove i tvrdnji da je on prije šest mjeseci napustio funkciju jer nije bio voljan trgovati hrvatskom teritorijom, slovenski mediji naglasili su da bi Sanaderov povratak na vlast mogao ugroziti arbitražni sporazum po pitanju graničnog spora između Hrvatske i Slovenije, koji je potpisan početkom novembra.
Because of his criticism of Kosor's government and claims that he left office six months ago because he was unwilling to trade Croatian territory, Slovenian media emphasised that Sanader's return to power could imperil the arbitration agreement regarding the border dispute between Croatia and Slovenia, which was signed in early November.
