ATHENS, September 11, 2008 (AFP) - Serbia on Thursday said a stalled pact on its European Union aspirations should be kickstarted now as it had fully complied with a UN tribunal investigating war crimes in the former Yugoslavia.

'We believe the time to act is now. We believe this is the time for the (interim agreement) process to be unfrozen,' Serbian Foreign Minister Vuk Jeremic told reporters in Athens.

'There was one political condition for Serbian accession to the EU...and that was full cooperation with the Hague tribunal. Serbia is fully cooperating with the Hague tribunal.

'I hope that come the next meeting of European Union foreign ministers (next week) this is going to be a consensus,' he said after a meeting with Greek counterpart Dora Bakoyannis.

The agreement is part of the Stabilisation and Association Accord, a trade and aid pact seen as the first step toward European Union membership.

It has been signed by the 27 EU nations and endorsed by Serbia's parliament, but remains suspended until Belgrade demonstrates 'full cooperation' with the Hague tribunal.

The court is demanding the arrest of former Bosnian Serb military chief Ratko Mladic, who was believed to be in hiding in Serbia, and has been indicted for genocide.

Mladic -- along with the Bosnian Serb wartime political leader Radovan Karadzic, arrested in Belgrade in July -- was charged over the 1995 massacre of 8,000 Bosnian Muslims in the Bosnian town of Srebrenica.
