During a long friendly conversation, the two officials exchanged opinions on the current situation in the region, the state of affairs in Serbia and Croatia, and on their relations.
Prince Aleksandar informed Mesic that according to opinion polls, 28 percent of Serbians support restoration of the monarchy, with 50 percent being in favour of the monarchy if they could be convinced that it is in the interest of their country.
Later in the day Mesic told the press that the Serbian crown prince expressed a wish to see "a relaxation of the relations" between Croatia and Serbia as well as a relaxation of overall relations in the region.
According to Mesic, Karadjordjevic would like to see capital from Europe and the world come to the region.
Asked by reporters what language they used in their communication, Mesic responded that they had talked in two languages.
"He (spoke) in Serbian and I in Croatian, and we understood each other very well," Mesic said.
Asked whether he was expecting negative reactions due to the role of the Karadjordjevic dynasty in the Croatian past, Mesic answered that "this one has not had any effect on what the Karadjordjevics used to do."
"What he is proposing are peace and tolerance among peoples and religions and it is quite acceptable," the Croatian President said.
Asked whether the prince perhaps made inquires about real estate in Croatia, Mesic answered that he thought the House of Karadjordjevic had no real estate in Croatia.
According to a press release issued by the Belgrade-based Office of Prince Aleksandar, during his stay in Zagreb the prince will also meet dignitaries of the Serb Orthodox Church and the Jewish and Muslim communities in Croatia.
His possible meeting with the primate of the Catholic Church in Croatia, Cardinal Josip Bozanic, could not be held owing to Bozanic's trip abroad.
The prince and his wife will also meet Croatian Serb representatives and Serbia's Ambassador to Zagreb, Radivoje Cveticanin, according to the press release.
