Cumulative freight volume on China's New Western Land-Sea Corridor rail services has passed six million twenty-foot equivalent units, it was reported on Sept. 11. The figure is cumulative since the corridor began operating.

The corridor is a multimodal route running from inland provinces such as Chongqing and Sichuan through the Beibu Gulf ports in Guangxi to Southeast Asia. Its design links rail and sea legs to shorten the distance compared with routing back to eastern coastal ports.

For inland regions the corridor is about time and cost. Routing via eastern ports lengthens the haul and adds inland freight charges; a direct southern exit reduces that burden.

Cargo has broadened to include auto parts, chemicals, agricultural goods and electronic components. Concentrated on a few categories at the outset, the shipper mix has diversified as service frequency rose.

On the Southeast Asian side, connections to Vietnamese, Thai and Singaporean services are seen as decisive, since port handling capacity and customs processing speed govern total transit time.

There is indirect relevance for Korean traders. When the route by which components made in inland Chinese plants reach Southeast Asian assembly hubs changes, third-country logistics firms carrying volume on that flow adjust their plans too.
