Pinglu Canal: 560 kilometres less to reach the sea

WEDNESDAY, 23 SEPTEMBER 2026

A 72.7 billion yuan investment and four years of works. But the vessels are river-sea craft: at the Gulf of Tonkin goods are transhipped as before.

The Pinglu Canal in Guangxi has been open to navigation since 16 September, after four years of construction: 134.2 kilometres connecting the river system around Nanning to the Gulf of Tonkin and cutting more than 560 kilometres off the route to the sea for goods from south-western China. It is the first river-to-sea waterway built in China since the founding of the People's Republic, and it concerns companies buying in that part of the country far more than it may seem.

The figures behind the project

The project was delivered with a declared investment of 72.7 billion yuan, about 10.8 billion dollars, and is sized for vessels of up to 5,000 tonnes. The projections circulated at the opening speak of logistics costs falling by 18 to 30% and annual savings above 5 billion yuan along the corridor: these are expected figures, not measured results, and should be treated as such.

• 134.2 kilometres long, from the Pingtang river at Hengzhou, in the Nanning area, to the Gulf of Tonkin.
• More than 560 kilometres saved compared with the previous route to the sea.
• Vessels up to 5,000 tonnes, with a design envelope of around 90 metres in length, 15.8 in beam and 5 metres of draught.
• 72.7 billion yuan of investment, about 10.8 billion dollars, and four years of works.
• Logistics costs projected to fall by 18 to 30%, with announced savings above 5 billion yuan a year: projections, not final accounts.

What the Pinglu Canal is for

Guangxi is a coastal region that nonetheless had no direct link between its river network and the sea: goods from the south-west followed the eastward export model, running down the Pearl River or the Yangtze to the deltas, with the familiar bottlenecks at the Changzhou and Three Gorges locks. The new canal opens a southern outlet and takes pressure off those routes.

In the Chinese design the canal is one piece of the Han-Xiang-Gui corridor, part of the national plan for high-grade waterways. The announced developments concern the Xiang-Gui canal towards Hunan and better sea access for Yunnan and Guizhou. These are projects, not existing infrastructure: the distinction matters when reading a promotional map.

What changes for importers from China

The practical point is the port of loading. Companies buying from suppliers in Guangxi, Yunnan or Guizhou today often see goods leave from Shenzhen or Guangzhou, after a long and expensive inland road leg. With the canal, the Gulf of Tonkin ports, Qinzhou first among them, become a more credible alternative because the inland leg moves onto water rather than trucks.

It is worth keeping in mind what the canal does not do. Vessels of 5,000 tonnes are river-sea craft, not ocean container ships: goods reach the Gulf of Tonkin port and are transhipped there, exactly as before. The ocean leg, the freight rates and the transit times towards Europe remain the ones set by liner services, and an inland canal does not touch those.

What it means for importers

The useful question to put to a supplier over the coming months is whether the port of loading changes and with what effect on the delivered price. Shifting the inland leg from road to water can reduce cost per tonne, but it often lengthens inland transit time: these are two different variables and it is worth having both quantified, rather than accepting the first as if it implied the second.

The second check concerns the actual liner services from Qinzhou and the other Gulf of Tonkin ports towards the Mediterranean. A port closer to the factory is worth nothing if sailings are few or if they require an extra transhipment: before rewriting a routing, look at the sailing schedule, not at the map of the canal.

What the 560 kilometres do not say

They state a distance, not a cost and not a time. How much of that distance turns into savings depends on inland navigation tariffs, on the number of transhipments and on the capacity the Gulf of Tonkin ports manage to bring into service: the canal opened days ago and there is still no traffic series to reason on.

The signal worth taking is one of direction, not of size. China is shifting shares of inland transport from road and rail onto water, and it is doing so where suppliers that many European buyers already use are located. Over the next two years it is worth asking rather than assuming.

With La Merce the port of loading of a south-western Chinese supplier is checked before signing, together with the delivered cost and the actual number of days: the Pinglu Canal may change both, but only the invoice proves it.
