Borrell was speaking at a joint press conference after talks with Croatian Prime Minister Ivo Sanader, who arrived in Strasbourg on Tuesday for a two-day visit to the European Parliament.
Borrell said the Parliament acknowledged everything Croatia had done to meet all demands and hoped it would settle the remaining problem, the situation concerning General Ante Gotovina, so as to eliminate the last hurdle on the road to the EU.
Sanader reiterated to the press Croatia was doing everything to demonstrate full cooperation with the Hague war crimes tribunal because it wanted to remove the last obstacle on its the road to EU membership.
The Croatian PM said that according to information at his disposal, the task force evaluating Croatia's cooperation with the Hague tribunal would meet on Sunday. He added he had discussed this with Borrell.
Sanader said Croatia was resolute regarding cooperation with the UN court not only because it was an international commitment, but also because it was bound to do so by its constitutional law.
He recalled that by the European Commission's assessment, Croatia had met all admission conditions, and said that Croatia was ready to start the entry negotiations the minute the task force evaluating Croatia and the Council of Ministers adopted a positive decision.
A member of the press asked for a comment on claims from Slovene deputies that Croatia was further and further from EU entry negotiations and that Gotovina posters were still being displayed in Croatia.
Sanader said Gotovina posters were no longer displayed in public areas in Croatia and that those claims might refer to posters displayed on private property, which he added was something the executive authority could not interfere in.
Sanader went on to say that despite a possible public perception to that effect, Croatia and Turkey were in no way connected because all EU admission candidates were evaluated individually.
He said Croatia did not have or want influence on the start of Turkey's EU entry negotiations. He said Croatia was going along its own way and hoped for a positive decision from the Council of Ministers' task force.
Borrell underlined that there was no connection at all between Croatia and Turkey on their way to EU membership.
Sanader once again confirmed that Croatia had no information, either from its own or foreign intelligence services, or from the Hague tribunal's Office of the Prosecutor, which might lead to the conclusion that General Gotovina is in Croatia.
Tonight the Croatian PM is scheduled to attend a meeting of the club of deputies of the largest faction in the European Parliament, the European People's Party, of which his Croatian Democratic Union (HDZ), the ruling party in Croatia, is a member.
On Wednesday he is due to meet the leaders of the other strongest factions, the European Social Democrats and the Greens, as well as Council of Europe Secretary-General Terry Davis.
