There are currently 24 routes in use for China-Europe freight trains via the three ports, transporting daily necessities, general merchandise, mechanical equipment, metals, agricultural products and timber between more than 60 Chinese cities and European cities in 14 countries.

In the second quarter, renovation projects are expected to begin on rail segments from Suifenhe to the national border. The Binsui Railway and the Xilingkou to Boketu section of the Binzhou Railway will be upgraded.

The group said these projects aim to address issues such as steep gradients, tight curves and low train speeds on existing lines. The goal is to improve the efficiency of train movement.

These projects will be important in helping to guarantee the shipping performance of China-Europe freight trains, the group said.
