"I think that today we solved the last issue that prevented Slovenia from ratifying the Croatian accession treaty. The initialling of the agreement was welcomed by the European Union too and this is a compromise whereby Slovenia has achieved its objective," Jansa said.
He said Slovenia's main goal was to return the issue of transferred foreign currency savings to the framework of succession to the former Yugoslavia, adding that Croatia had achieved its goal too because the Slovenian parliament would now ratify its EU accession treaty.
"The ratification (of the treaty) was completed or has at least begun in virtually every EU member state and I think there are now serious arguments to expect that Croatia will become a full member on July 1 this year," Jansa said.
"With Croatia's EU accession, all four Slovenian neighbours will be members, and with Croatia entering the single European economic zone the customs border will disappear, although the Schengen border will remain for a few more years."
The outgoing PM advocated a reform policy in Slovenia, saying Slovenia would thus set an example to the Western Balkan countries aspiring to EU membership.
Slovenia is interested in their EU accession all the more so because it expects that this will expedite the solving of the succession issues between the successors to the former Yugoslavia, said Jansa.
"One of the additional motives for Slovenia's interest in the European Union continuing to expand in the Western Balkan region is the fact that the states, when they join the EU or immediately before that, will be more interested in solving the succession issues."
He said it would then be easier to solve those issues and that this was why the 2001 succession treaty was important also in terms of EU enlargement.
