The North-South Economic Corridor (NSEC) – linking Kunming to Bangkok, Kunming to Hanoi, and Hanoi to Nanning –is the main route of GMS Economic Corridors will focus on connecting southern China (Yunnan) to the region through the streets in the north - south. The beginning of the road in the north - south is the city of Kunming and end points are separated into two lines, Thailand and Vietnam.
The NSEC will play a critical role in providing Yunnan Province and northern Lao PDR access to important sea ports. Potential market coverage is extensive, given the existing road network from Singapore via Malaysia to Chiang Rai, and from Kunming to Beijing. The corridor is virtually complete, except for a bridge between Lao PDR and Thailand, which is to be constructed soon.
