Vietnam’s Ministry of Construction has confirmed that the planned Haiphong–Ha Long–Mong Cai railway line, spanning approximately 187 km, will be developed after 2030 under the national railway master plan for 2021–2030 with a vision to 2050. The line, starting from Nam Dinh Vu station in Haiphong and ending in Mong Cai (Quang Ninh), will use a 1,435-mm standard gauge and be fully electrified.

Once developed, the line is expected to strengthen trade connectivity with Dongxing in China, boost regional logistics efficiency, and facilitate stable, sustainable export channels for agricultural, forestry, and seafood products from Vietnam to China.

Currently, the Haiphong–Ha Long–Mong Cai corridor is served mainly by waterways and roads. Waterway transport remains dominant due to its low cost, while road connectivity has improved significantly with the opening of the Ha Long–Mong Cai expressway. Under the master plan, the corridor will eventually integrate all three transport modes—sea, road, and rail—to enhance multimodal capacity. The ministry noted that the railway’s investment will proceed once international intermodal transport demand increases substantially.

As part of the preparatory phase, the Ministry of Construction has assigned the Vietnam Railway Authority to work with Chinese authorities to develop a detailed alignment plan for the cross-border section. This collaboration aims to ensure seamless integration with China’s railway network and strengthen trade corridors between the two countries.
