Palkovics said representatives of the four countries discussed what infrastructure would be necessary to build. He added that the importance of the quality of rolling stock must be acknowledged.

He noted that goods need 45 days to reach Europe from China by sea, but just twelve days by rail. He also pointed to the goal of raising the share of freight transported by rail in the European Union from 20% to 50% by 2050.

The working group participants also agreed to review the possibility of making developments in the passenger segment, Palkovics said.

The working group will next meet in October, on a train on the Budapest-Belgrade line, he added.
