Yunnan has been establishing itself as a gateway linking China, South Asia and Southeast Asia. 

The China-Vietnam Railway traversing Yunnan had been operational since 2014. The China sections of another four international railways are also under accelerated construction. Among them, the 330-km Dali-Ruili line will pass by a number of key towns in the region with a design speed of 140 km/h.

“The railway will make its way through the Gaoligong Mountains with extremely complex geographic terrains and geological conditions. So it takes more time,” introduced a local official.

The latest news show that the roughest tunnel project of the railway construction has seen surprising advancement, and the railway is expected to be commissioned as of 2021 based on the current construction speed.
