"That would be unnecessary and harmful to good neighbourly relations," Tadic said at a press conference in the central Adriatic town of Zadar.
Tadic said that February 10 was the day when "Italy commemorates the loss of the territory it had grabbed" and that "all Italy is interested in is to dismantle the Osimo Accords."
"Italy is bound by the accords not to make any new claims, and to speak about the return of property today means forcing the Croatian government to pay for the failure by the Italian government to indemnify Italian WWII refugees," he said.
The HSP vice-president said that Croatia should never agree to it, and that the Croats and the Italians should overcome the present situation the way the Germans and the Czechs had. "This historical chapter must be closed," he said.
"If Italy wants to reopen this issue, then Croatia must open the issue of compensation for victims of Italian camps in Croatia," Tadic concluded.
Meanwhile, the head of the Italian Union and member of the Croatian Parliament, Furio Radin, suggested that Mesic and Italian President Giorgio Napolitano should meet as soon as possible, and that Slovene President Janez Drnovsek should also join them in efforts to bring about reconciliation among all sides.
Speaking to reporters in the northern Adriatic town of Pula, Radin expressed concern on the part of the Italian national community in Croatia and Slovenia about developments following an exchange of barbs between the Italian and Croatian presidents.
"We believe that this whole debate is not in the spirit of tolerance and co-existence we have been building all these years in Istria and Rijeka," Radin said.
"All of us people of goodwill must put a stop to this debate, and we should tell the presidents of the two countries and Croatian and Italian politicians that in future talks they should focus on their own sins because so far everyone has mostly been talking about other people's sins," he said.
"Since problems between Italy and Croatia, and previously between Italy and Yugoslavia, always had negative consequences for the Italian national minority and Istria County, I propose closing this debate as soon as possible," Radin said.
Radin said he was pleased with the positive tone of the Croatian government, praising Foreign Minister Kolinda Grabar Kitarovic's attempts to alleviate the tension.
