The draft resolution, written by the refugees' representatives, has already already been sent to parliamentary parties, the Serbian Beta news agency reported.
Refugee leader Miodrag Linta was quoted as saying that they demanded that all relevant institutions stopped Croatia's integration into the European Union until all issues related to Serb refugees were solved.
The draft resolution urges the Serbian parliament to ask the government to define a basis for negotiations with the Croatian government with a view to finding lasting and comprehensive solutions to refugee issues, according to refugee leaders.
A copy of the petition with signatures has already been forwarded to President Boris Tadic.
Representatives of Croatian Serb refugees started collecting signatures on December 15, demanding the settlement of 12 outstanding issues, including the restitution of moveables and real estate, the reconstruction of property destroyed in "terrorist actions" during the 1991-95 war, compensation for damaged and missing real estate and moveables, the restitution of tenancy rights or equitable compensation without conditions or restrictions, the payment of back pensions and recognition of years of service, a review of war crimes sentences passed in absentia, "the fair and balanced prosecution of war crimes and putting an end to ethnically-motivated trials."
In mid-February Linta said copies of the petition with 45,000 collected signatures would be forwarded to the Serbian government and parliament, the highest European bodies, the US, Russian and Chinese embassies, and to Serbian President Boris Tadic.
Commenting on this action of Croatian Serb refugees in Serbia, Croatian President Ivo Josipovic said on Tuesday morning that "there are people who perhaps have reason to be dissatisfied, but I think that Croatia is showing good progress in solving those problems and there is no need to throw spanners into the wheels."
