Speaking at a press conference in Parliament, Djapic said that in compensating the so-called Danubian Germans now living in Austria and Germany, Croatia should not go beyond the level of compensation carried out by Poland, the Czech Republic and Slovenia.
The HSP leader said that he believed the initialled agreement would not win the necessary two-thirds majority in the Croatian Parliament and that the Government would withdraw it.
Djapic warned that the public conflict between the President of the Republic and the Government over the agreement was harming the country's international reputation.
Commenting on the initiative by Slovene Foreign Minister Dimitrij Rupel, that European Foreign Policy Commissioner Xavier Solana should arbitrate in the border dispute between Croatia and Slovenia, Djapic said he was sorry about the absence of Croatia's response to the proposal.
"We in the HSP respect Solana and believe that he can be a good mediator, but not an arbiter in this dispute," he said, adding that it was unacceptable for the border dispute to be treated as a political issue.
Djapic said that Croatia should insist on the border dispute with Slovenia to be resolved before an international judicial institution, preferably the International Court of Justice in The Hague.
Djapic also urged a new analysis of the border agreement with Bosnia-Herzegovina to determine whether two disputed islets, Veliki Skolj i Mali Skolj, and the Klek peninsula belonged to Croatia.
