"It would be good for Deputy Prime Minister and Croatian Democratic Union (HDZ) presidential candidate Jadranka Kosor to have obtained relevant information first and then make comments," the President's Office said in a statement released on Sunday.
The statement reads that President Mesic said that "Croatia was never at war with Montenegro and Serbia until the recent war, which was caused by Milosevic".
"The President made the statement in the context of European cooperation, saying that if in united Europe France and Germany were able to open borders and cooperate, and even lead the way in democracy and European integration, so are we," reads the statement, signed by the head of Mesic's public relations department, Danijela Barisic.
The statement reads that "Montenegrin politicians made apologies at meetings with President Mesic - Milo Djukanovic did so in Dubrovnik in 2000, and Serbia and Montenegro President Svetozar Marovic after a meeting with Mesic in Belgrade in 2003, which Deputy Prime Minister Kosor condemned on behalf of the HDZ."
"In that context, the latest statement by the politician who at the time did not understand the far-reaching effects of the apology is not surprising, just as today she obviously does not understand the process of European integration and the parallel which President Mesic drew by taking as an example France and Germany and Croatia and Serbia and Montenegro."
"Pretending to care for the dignity of war veterans is nothing but an attempt to score cheap political points in the election campaign," reads the statement.
Kosor today resolutely dismissed Mesic's statement that "Croatia and Montenegro were never at war", calling it an attempt to revise the Homeland War.
President Mesic stated that Croatia and Montenegro had never been at war while speaking about the benefits of European integration after a meeting with Montenegrin Foreign Minister Miodrag Vlahovic on Saturday.
"If after so many wars in their history the Germans and the French could open borders and cooperate, and now even lead the way in democracy and European integration, then we, who were never at war in this region, can do it too. We were never at war with Montenegro," Mesic told the press after meeting Vlahovic.
