He is the vice president of the Independent Democratic Serb Party and chairman of the Croatian parliamentary Foreign Affairs Committee.
"We are waiting with great interest for the takeover of the presidential duty to be completed and for the formation of the government so that all possible doubts, as to whether those relations can continue to develop as until now, can be eliminated," Pupovac told Belgrade's Blic daily of Thursday when asked if Tomislav Nikolic's election as Serbia's president and his contentious statements were a brake on Croatian-Serbian relations.
Pupovac said he had still not received an invitation to Nikolic's inauguration on June 11, adding that if he received it, out of respect for the institution of Serbia's president, he would "find a way to make the best decision."
He said Croatian President Ivo Josipovic and former Serbian President Boris Tadic had done a lot to improve relations between the two countries, and that he expected this would not be undermined by Nikolic's statements.
Pupovac said it was especially important to maintain the confidence, which included the relationship towards the war, the victims and the suffering, and that it was essential not to compromise all that with statements that did not sufficiently take into account the sensitivity of real human suffering.
Asked if he could imagine Nikolic's first visit to Croatia, Pupovac said Nikolic should come to Zagreb and that what would happen between Croatia and Serbia depended a lot on his political moves.
The Croatian public and political leaders have recently condemned an interview which Nikolic gave to Frankfurter Allgemeine Zeitung daily before the May 20 presidential runoff, in which he said that the project of a Great Serbia was his "unrealised dream" but that he respected Croatia's internationally recognised borders, and that Croats had no reason to return to Vukovar, eastern Croatia "because it was a Serbian town".
