Jansa presented his position on the matter at a regional meeting of the Visegrad Four consisting of Hungary, the Czech Republic, Poland and Slovakia plus Slovenia and Austria.
The meeting in the Hungarian capital of Budapest, in which also European Commission President Jose Manuel Barroso took part, focused on EU expenditure between 2007 and 2013 and the situation in Belarus, as well as on the opening of entry talks with aspirants for EU membership, namely Turkey and Croatia.
According to a press release issued by the office of the Slovene Prime Minister, Jansa and many other participants in the informal meeting cautioned that the possible launching of entry talks only with Turkey and not with Croatia would lead to "a very peculiar situation".
"This was more or less a unanimous position. Slovenia as well as most countries-participants supported the start of the negotiations with Croatia," Jansa said in Budapest.
EU foreign ministers, who are scheduled to hold an informal meeting this week in Great Britain, the current EU chair, are expected to discuss this matter among other things.
