In Mohan, a small town in Yunnan province bordering Laos, construction of the Friendship Tunnel is making brisk headway seven days a week.

The 9.68-kilometer railway tunnel will connect both sides of the border, with 7.17 km in China and 2.51 km in Laos.

Boring the tunnel began in June 2016. Running slightly behind schedule due to challenging geological conditions, the project is scheduled for completion in July 2019.
