The two sides agreed on cooperation in the exchange of information on integration and functioning in the EU, and Kokalj welcomed Croatia's proposal to introduce regular meetings on the EU and integration processes between the two committees.
"The future joint membership in the EU will strengthen our neighbourly relations," Mimica said after the meeting, adding that the talks focused on cooperation between the committees, integration process and problems with the ratification of the EU Constitution.
The Croatian official reiterated that his country was grateful for the support the Slovene government and parliament continued to give Croatia in its efforts to start membership talks with the EU as soon as possible.
Kokalj said his country believed that the situation regarding the EU Constitution would not stop but perhaps slow down the process of EU enlargement.
Slovene reporters asked the two officials to comment on Slovene press reports saying that the nationalist wing of the Slovene People's Party (SLS), led by Josko Joras and Marjan Podobnik, was considering calling a referendum at which Slovene citizens would decide if they supported Croatia's integration with the EU.
Kokalj first would not comment on the question, but pressed by reporters said that one should be cautious with such issues and that referendums could also have negative consequences. "That would be possible only if a decision was adopted at the highest political level," he said.
The National Alliance of the SLS, which does not abide by the disciplinary rules of the party, that is a member of the ruling centre-right coalition led by Prime Minister Janez Jansa, has put forward a proposal for such a referendum.
The National Alliance issued a statement on Wednesday saying that it could start collecting signatures for the referendum if Croatia continued with "territorial aspirations towards Slovenia".
Asked to comment on the speculation about the referendum, Mimica said that the two countries' relations could not be threatened by any issue and that their future common European environment would provide better prospects for the settlement of outstanding issues.
