Serbia's new bridge links nations as well as parts of Belgrade

It was an absolutely grand sight when tens of thousands of local people stood along the Zemun-Borca bridge, waving Chinese and Serbian flags and cheering.

That was how they showed their enthusiasm about Premier Li Keqiang's visit to the city's first new link over the Danube in 70 years.

As Li and his Serbian counterpart, Aleksandar Vucic, cut the ribbon and announced that the bridge was officially complete, the huge crowd, from youngsters to senior citizens, responded with warm applause.
