In attendance were representatives of Croatia, Bosnia and Herzegovina, Albania, Macedonia, Montenegro, Serbia, Kosovo, and the European Commission.
The EC estimates that two billion euros should be invested in the region's rail infrastructure by 2020 so that it could meet minimum effectiveness standards.
A state secretary at the Croatian Transport and Development Ministry, Drazen Breglec, said Croatia would continue to set aside four per cent of GDP for the transport infrastructure. He added that investment would focus on railways after 85 per cent of highways were completed in 2008.
European Transport Commissioner Jacques Barrot said the development of an appropriate and reliable transport network was a prerequisite for economic progress in the region and social integration. He added the rail infrastructure would also help expand the European market and provide for a more harmonious development of the continent.
