dexinwin In an era of high-speed rail and extensive expressway networks, why would China spend more than 70 billion yuan building a 134.2-kilometer canal in Guangxi?
That question has attracted renewed attention following the opening of the Pinglu Canal in September.
The Pinglu Canal officially opened to navigation on September 16, 2026. The project cost approximately 72.7 billion yuan and stretches 134.2 kilometers. Built to China's Class I inland waterway standards, it can accommodate vessels of up to 5,000 tonnes. It is the first canal project since the founding of the People's Republic of China to be planned and coordinated at the national level specifically to connect inland waterways with the sea.
For many people, spending more than 70 billion yuan on a canal may appear difficult to understand.
After all, high-speed trains can move people between major cities in just a few hours, while China's highways have become increasingly comprehensive.
So why build a waterway that appears much slower?
The answer lies in a fundamental distinction:
High-speed rail is designed to move people quickly. Canals are designed to move large volumes of goods at relatively low cost.
High-Speed Rail Is Fast, But It Cannot Replace Water Freight
Modern transportation is not simply a competition over speed.
High-speed rail is highly efficient for passenger travel. Roads provide flexibility. Railways are well suited to stable, large-scale freight transportation. Inland waterways, meanwhile, have a major advantage when it comes to moving large quantities of bulk cargo at relatively low unit costs.
Coal, ore, grain, steel, construction materials and containers do not necessarily need to arrive as quickly as passengers.
For these commodities, transportation cost, capacity and efficiency can matter more than speed.
That is why a waterway connecting an inland economic region with a seaport can have significant economic value even in an era dominated by high-speed rail.
The Pinglu Canal Addresses a Longstanding Problem
Guangxi faces the Beibu Gulf and has access to major coastal ports, but southwestern China's inland regions have historically lacked a direct high-capacity waterway linking them with the gulf.
Before the Pinglu Canal, some cargo from southwestern China had to travel eastward through the Xijiang water system before reaching ports in the Pearl River Delta.
Another option was to move cargo by road or rail to coastal ports.
Both approaches have limitations, particularly when dealing with large volumes of bulk goods.
The Pinglu Canal changes that geography by connecting the Xijiang shipping system directly with the Beibu Gulf.
In simple terms, it creates a new route allowing cargo from southwestern China to move southward toward the sea.
Chinese public information on the project says the canal will allow inland vessels to reach the Beibu Gulf directly and significantly shorten shipping distances for cargo from southwestern regions.
What Can More Than 70 Billion Yuan Actually Buy?
The investment should not be evaluated simply by asking how much the canal cost to build.
The more important question is how much economic friction the new waterway can remove over decades of operation.
According to publicly reported figures, the canal can shorten inland shipping distances for southwestern cargo by more than 560 kilometers. Overall logistics costs are expected to fall by around 18% to 30%, while annual transportation savings for society could exceed 5 billion yuan.
These figures illustrate why the project's value goes beyond the canal itself.
A major transportation project can alter how goods move, where companies locate and how easily inland economies connect with international markets.
Lower Logistics Costs Could Change Industrial Geography
For a manufacturer, producing a competitive product is only part of the challenge.
The cost of delivering that product to customers also affects competitiveness.
If a factory has to rely on expensive land transportation and multiple transfers, logistics expenses can weaken its position in distant markets.
A more efficient waterway can reduce those costs and potentially expand the effective market radius of inland businesses.
This is why the Pinglu Canal is more than a transportation project.
It can become an economic corridor connecting production areas with ports and overseas markets.
Why the Beibu Gulf Matters
One of the most important aspects of the project is its connection to the Beibu Gulf.
The Pinglu Canal begins at Pingtang River in Hengzhou, Guangxi, passes through Lingshan County in Qinzhou and eventually reaches the Beibu Gulf through the Qinjiang River.
The gulf is strategically positioned for trade with Southeast Asia.
That means the canal is not simply designed to improve transportation inside Guangxi. It is intended to connect inland southwestern China more efficiently with coastal ports and international markets, particularly the ASEAN region.
On the day the canal opened, direct river-sea freight routes connecting Nanning Port with Can Tho, Vietnam, and Nanning Port with Yangpu Port were launched.
This illustrates the broader goal: creating a more integrated logistics chain from inland waterways to the canal, then to seaports and international shipping routes.
The Bigger Question Is Regional Development
A 72.7-billion-yuan project is undeniably a major investment.
But the long-term assessment cannot be based only on construction costs.
The real test will be whether the canal can sustainably reduce logistics costs, increase cargo flows, support port development and attract new economic activity along the corridor.
That is how major infrastructure projects create value.
A railway is not valuable simply because trains run on it.
A highway is not valuable simply because cars can drive on it.
And a canal is not valuable simply because ships can sail through it.
The real question is whether the infrastructure makes economic activity more efficient.
Why Build Canals in the Modern Era?
The Pinglu Canal is also part of a broader effort to improve China's integrated transportation network.
Projects involving connections between the Beijing-Hangzhou Grand Canal and the Xiaoqing River, as well as proposals involving the Zhejiang-Jiangxi, Jiangxi-Guangdong and Hunan-Guangxi waterways, are part of a wider discussion about expanding the country's high-level inland waterway network. By 2035, China plans to basically establish about 25,000 kilometers of national high-level waterways under its comprehensive transportation strategy.
This does not mean waterways are replacing high-speed rail or highways.
Instead, the goal is for different transportation systems to perform the tasks for which they are most efficient.
People generally value speed.
Freight operators often value capacity, cost and reliability.
That distinction explains why waterways remain economically relevant.
Is Spending More Than 70 Billion Yuan Worth It?
There is no immediate answer.
The long-term value of the Pinglu Canal will need to be measured through cargo volumes, port activity, logistics costs, industrial investment and regional economic growth over many years.
But the project clearly addresses a structural problem that has existed for decades:
Southwestern China has enormous economic and freight activity, but historically lacked a high-capacity direct waterway connecting its inland regions with the Beibu Gulf.
That connection now exists.
The more than 70 billion yuan therefore did not simply buy 134.2 kilometers of artificial waterway.
It created a new logistics route, a new connection between southwestern China and the sea, and potentially a new foundation for reshaping the region's economic geography.
From the perspective of passenger transportation, canals may look slow.
From the perspective of bulk freight, however, speed is only one part of the equation.
The more important questions are:
Can a tonne of goods travel farther at a lower cost? Can inland regions reach international markets more efficiently?
Those questions help explain why, even in the age of high-speed rail, China is still investing heavily in canals.
