Sanader said Croatia had achieved democratic standards and was now a state nurturing tolerance without any discrimination.
Croatia wants democratic dialogue and the application of all European values, he said, underlining that over the past 11 years the OSCE Mission had played a positive role in Croatia, helping it achieve progress in all areas, as well as in the region.
Speaking of outstanding issues, Sanader said the government was ready to close them by the end of the year through stronger cooperation with the OSCE Mission, thus bringing its mandate to a close.
Sanader reiterated that Croatia expected to be extended an invitation in Bucharest next year to join NATO, underlining that Croatia's goal was the permanent stabilisation of Southeast Europe.
Speaking to the press afterwards, Sanader said he was pleased with the reaction of the OSCE countries which took part in a debate after his speech - the US, Canada, Bosnia and Herzegovina, Serbia, Russia and EU president Portugal.
Croatia is a mature state which has overcome all the difficulties from the war years in the first half of the 1990s, a mature member of the international community drawing closer to NATO and EU membership, he said.
From a country which received assistance, Croatia has become a country providing aid to countries in need, he said, recalling that several Croatian diplomats are engaged in OSCE and other peace missions around the world, whereby Croatia is making its contribution to world peace and stability.
Sanader said the participants in the debate commended Croatia's progress and democratic maturity, and that no one pushed for extending the OSCE Mission's mandate in Croatia.
He also commented on two outstanding issues the Mission would tackle in the coming months, the first being the trial against generals Rahim Ademi and Mirko Norac, referred from the Hague war crimes tribunal, and possibly other cases to be referred from the UN court.
Sanader said there was no reason against having OSCE experts observing the trials, adding that if the national judiciary had not demonstrated its maturity and efficiency, the Hague tribunal would not have referred the case.
The second issue is the completion of refugee return and full integration of minorities in Croatian society, Sanader said.
His address to the OSCE Permanent Council was the first by a Croatian prime minister. Sanader said it was an honour, that the address was excellently received, and that "our friends, as well as those others who disagree, will have reason for optimism".
