Ankara: Serbia's leader Wednesday called on the European Union to openly tell his country "without making any excuses" whether it wants Serbia to join the 27-nation bloc or not.

Turkey's president Abdullah Gul also urged the EU to refrain from delaying membership process.

The criticism by Serbian President Boris Tadic comes despite assurances by the EU earlier this month that the door remains open to Croatia, Serbia, Bosnia, Albania, Kosovo, Macedonia and Montenegro if they meet its criteria for joining.

The EU's conditions for membership include strengthening of the rule of law, fighting against corruption and organised crime, guaranteeing media freedom and regional cooperation. So far, no nation in the region has qualified, with Croatia the closest to join probably in 2012. The Balkan states are concerned EU members may not want to expand given the current financial crisis. The Balkan officials argue that EU enlargement did not cause the crisis and should not be delayed.
