Serbia must achieve full cooperation with the Hague tribunal, there is no doubt about that or any privileges, although practical assistance on our part is possible, Plassnik said after talks with Serbian President Boris Tadic.
Tadic said he expected Serbia's government to "launch the initiative" and implement the action plan with the assistance of EU institutions.
"Serbia's first strategic goal is to become an EU member, and all obstacles on that road will be eliminated," said Tadic.
He told Plassnik that his tour of the region's countries this week was aimed at sending out a message of peace, stability and cooperation after Serbia became a member of the UN.
Plassnik also held talks with Foreign Minister Vuk Draskovic, who told the press "the EU's position is clear -- negotiations with Serbia on a Stabilisation and Association Agreement will not resume unless war crimes indictees are extradited to the Hague tribunal".
Draskovic said Serbia must swiftly adopt and apply the "European action plan, which would be stronger than the anti-European plan which has been conceived and is being implemented by two parties of the former regime that are against Serbia's European integration".
"The action plan of democratic forces in Serbia envisages that former President Slobodan Milosevic's people be removed from secret services, the judiciary, the police and the media," said Draskovic.
The EU will continue to help and support Serbia, but it is up to you whether you will take that road, said Plassnik.
She also met Prime Minister Vojislav Kostunica. The two officials were agreed it was of outstanding importance that Serbia continue the SAA negotiations, a statement said.
Plassnik also met Deputy PM Ivana Dulic-Markovic. They agreed that democratic forces in Serbia must cooperate among themselves and with the international community so that reforms in Serbia could be successfully completed.
