The report was adopted at the committee's plenary session in Brussels on Thursday.
The committee called on Croatia to resolve the dispute regarding the sea border but not regarding the land border, which is why most Slovene members on the committee voted against the report, the Slovene members told STA.
The committee rejected for procedural reasons the Slovene proposal that the issue of both the sea and the land border be settled by neighbouring countries.
The committee said in a press release the final objective of the entry negotiations the EU launched with Croatia last week was the country's full EU membership.
The committee reiterated that Croatian authorities had repeated on a number of occasions that they were willing to cooperate fully with the UN war crimes tribunal in The Hague, and voiced hope this cooperation would soon yield tangible results.
