She was talking on Croatian Radio on Sunday after her first meeting with Serbia's new Foreign Minister, Ivan Mrkic, during the UN General Assembly session in New York earlier in the week, saying they "precisely defined" the topics.
"We have too much responsibility to today's and future generations to leave that outstanding as a mortgage on future relations, so we precisely defined what it's about."
Pusic said the first topic was the issue of missing persons and that when it was solved, it would leave room for the second most important issue, "European future and European reforms in our part of the world and cooperation between Croatia and Serbia."
Pusic said there was no point to talk about withdrawing the genocide suits both countries filed against each other and other topics related to the 1991-95 war before the issue of the war missing was discussed.
She said cooperation between the judicial systems was also important, saying they should have a standard procedure for war crimes trials. She said talks on the matter had begun and that the two countries should agree how to treat those cases.
Serbian President Tomislav Nikolic reiterated at the UN General Assembly that Serbia would never recognise Kosovo, with Pusic saying this was not an issue at present because the European Union did not insist on the recognition this early in Serbia's process of drawing closer to the EU.
She said mutual tolerance was necessary, "in which the recognition is not on the agenda but isn't absolutely ruled out either."
Pusic reiterated that the issue of Slovenian Ljubljanska Banka's debt to former Croatian depositors had nothing to do with Slovenia's ratification of Croatia's EU Accession Treaty. She reiterated Croatia wanted to discuss the debt issue, "but we don't want to mix that with the ratification issue," as well as that this was "obviously a bilateral matter" and that she would "like us to show enough seriousness and maturity" to solve it.
Regarding the proposal to ratify a Croatian-Bosnian border agreement, Pusic said the ratification was in Croatia's interest and that a consensus in the Croatian parliament was not in question.
