For Southwest China, the opening of the 134.2-kilometer Pinglu Canal represents a strategic leap forward, not merely an infrastructure addition. Officially opened to navigation on September 16, this is the first canal since the founding of New China to be constructed under national-level planning, directly connecting rivers to the sea. Its route links the Xijiang Golden Waterway in the north to the Beibu Gulf via Qinzhou, effectively straightening a previously circuitous connection between the country's southwestern hinterland and the ocean. This creates a shortest waterway for the region to reach the sea and establishes the most direct shipping channel for Southwest China to access ASEAN markets.
Even before the canal opened, Guangxi Tianyi Changlong Port Co., Ltd. (Tianyi Changlong) had already redefined its strategy, pivoting from a purely seaport terminal to a crucial node for river-sea intermodal transport. Operating nine berths and 700,000 square meters of storage yard in Qinzhou Port, the company previously relied on "North Coal South Transport" and imports, with virtually no exports. Now, traders along the Xijiang River are proactively seeking partnerships for overseas shipping. Li Huanan, acting deputy general manager, called this "a strategic upgrade"; however, the canal's economic impact extends far deeper than simply adding another shipping route.
Shorter Route by 560 Kilometers, Saving Over 5 Billion Yuan Annually
The first significant benefit is a reduction in logistics costs. Previously, cargo from the Southwest traveling by water had to follow the Xijiang-Pearl River route eastward, bypassing the Pearl River Delta. The inland voyage from Nanning to Guangzhou's Nansha Port exceeded 800 kilometers. Now, ships on the Xijiang can turn into the Pinglu Canal at Pingtang River Estuary, pass through Hengzhou, and head south to the Beibu Gulf and out to sea via Qinzhou Port, cutting the journey by roughly 560 kilometers. For vessels, this distance reduction translates directly into shorter transit times. For example, bulk cargo from Baise, Guangxi, now takes nearly half the time to reach the coast compared to the traditional route. Guangxi Rongxing Zhongke Development Co., Ltd., a paper company in Hengzhou, previously saw its goods take about seven days to reach Huangpu Port in Guangdong; via the canal, they now reach the estuary in about one day.
This time saving converts into significant financial gains. Zhang Zhiwen, Deputy Secretary-General of the Guangxi Zhuang Autonomous Region government, noted that shipping via the canal reduces comprehensive logistics costs by 18%-30% compared to traditional routes, saving society over 5 billion yuan annually in transport expenses. "Shortening the journey by hundreds of kilometers saves 5 billion yuan a year," he said, highlighting the tangible dividends for lowering business costs, boosting trade, and increasing incomes.
Beyond distance, water transport inherently offers advantages over road and rail for long-distance haulage of bulk goods and containers due to its larger capacity and lower cost. The average freight cost per ton-kilometer on inland waterways is about a quarter of rail and a fifteenth of road. Since the Pinglu Canal is built to Class I inland waterway standards, able to accommodate 5,000-ton vessels, unit transport costs are further reduced. Liu Yunzhong, a researcher at the Development Research Center of the State Council, noted that logistics costs typically account for 5%-10% of sales for general industrial goods. He estimates that using the canal could boost profit margins for industrial products by 1 to 3 percentage points, with an even greater impact in the Southwest where logistics costs are higher.
For specific companies, these savings are tangible. Zhang Zengtang, deputy general manager of Guangxi Guangtou Qiangqiang Carbon-Based New Materials Co., Ltd. (Guangtou Qiangqiang), calculated that his company's new carbon-based material project in Qinzhou purchases about 680,000 tons of raw materials annually. Previously reliant on long-distance road transport, the canal now enables river-sea intermodal shipping, saving 60 yuan per ton in materials logistics costs, totaling 40.8 million yuan annually. These savings are earmarked for R&D and market expansion to develop higher-value products and strengthen channels in the Southwest and ASEAN. Ding Jinxue, director of the Comprehensive Research Office at the National Development and Reform Commission's Institute of Comprehensive Transportation, stated that the Pinglu Canal effectively solves the problem of the Southwest's inland regions accessing the sea, opening a new, large-capacity, low-cost, and green river-rail-sea transport corridor.
Industrial Growth Flourishes Along the Waterway
While the logistics account saves on freight, the more subtle transformation is happening on the industrial side. The Qinzhou carbon-based new materials project by Guangtou Qiangqiang is the first industrial project from the Guangtou Group to participate in the Pinglu Canal Economic Belt. It is a key project to complete the group's coastal circular aluminum industry cluster in Beihai, Fangchenggang, and Qinzhou. Zhang Zengtang explained that while these coastal areas have concentrated aluminum production capacity, they lacked local supply of carbon-based pre-baked anode materials, a critical consumable. The Qinzhou project fills this gap, creating a closed-loop supply chain from raw materials entering the port, to local production, and supply to electrolytic aluminum plants. The canal was a decisive factor in choosing Qinzhou, given the city's advantages in raw material transport and access to Beibu Gulf policy incentives.
The canal is transforming entire industries and regions. Guangxi is now developing a "leaf-vein" industrial layout oriented towards the sea, with the Pinglu Canal Economic Belt as the main artery for large-volume, port-appropriate industries, and other areas as branches for specialized and emerging sectors. This core zone spans 33 counties across eight cities, including Nanning, Beihai, Fangchenggang, and Qinzhou. In Nanning, at the canal's starting point, industries like battery materials and high-end paper are clustering; the Liujing Industrial Park alone has attracted 280 enterprises. Guigang is building a "one corridor, multiple parks" pattern along the Xijiang. Chongzuo is focusing on a 100-billion-yuan non-ferrous metals cluster. From January to July this year, the 33 pilot areas along the economic belt signed 448 new projects, accounting for over a third of Guangxi's total investment. Port and supporting industries are also gearing up. Li Huanan predicts explosive growth in port shipping, logistics, warehousing, and trading, evolving from simple freight handling to a comprehensive "logistics + trade + industry" service system. COFCO Oils (Qinzhou) Co., Ltd., a major grain and oil processor, has signed a service agreement with the Beibu Gulf Port Qinzhou Terminal to improve efficiency and reduce energy costs through shared resources.
Wu Peng, chief designer of the Pinglu Canal project, explained that the canal was designed with provisions for future growth, capable of handling 5,000-ton vessels and planned for 2035 and 2050. The projected annual freight volume for 2050 is 120 million tons, which could potentially reach 180 million tons under optimistic scenarios. However, Wu emphasized that the canal's role is to stimulate economic development; the specific industrial layout is driven by market forces. The project focuses on setting reasonable transport forecasts and standards to provide the necessary infrastructure, while future economic growth will be guided by the market.
Greater Benefits from ASEAN Engagement
The most significant "big picture" calculation involves openness. At the Funing Port project in Wenshan Prefecture, Yunnan, a prominent sign reads: "Yunnan goes to the sea from here." Once projects like Funing Port and the Baise Hydraulic Complex are completed, goods from Yunnan can travel by water via the Youjiang-Xijiang-Pinglu Canal route to the Beibu Gulf and then to ASEAN markets, creating the most convenient golden waterway for Yunnan's exports. Guizhou's goods can also access the canal via the Nanpanjiang and Duliu rivers, and Sichuan and Chongqing can ship by rail to Guangxi before transferring to inland waterways. The canal provides the entire southwestern hinterland with its own gateway to the sea. Ding Jinxue noted that it will further optimize the national comprehensive transportation network, boost cross-border logistics, and improve transport convenience with ASEAN countries. On the canal's opening day, the first voyage on the "Nanning Port - Can Tho Port, Vietnam" river-sea direct route was launched, carrying goods like chemical fibers from Zigong and sodium sulfate from Chengdu. A total of thirty cargo ships used the canal on its first day.
Liu Yunzhong views the canal as a crucial complement to the New International Land-Sea Trade Corridor, transforming the Southwest from a hinterland into a frontline for ASEAN engagement. Based on the canal's low-cost water transport, Guangxi, Yunnan, and Guizhou can develop industries like phosphate chemicals, green new materials, paper, and grain processing, supplying processed minerals and agricultural resources to ASEAN manufacturers. The canal can also enhance cross-border park cooperation, facilitating a two-way industrial chain where ASEAN resources are processed in the Southwest, and Southwestern products are used in ASEAN manufacturing. Wu Peng suggested that trade relations could evolve into deeper industrial collaboration. Using the auto industry as an example, China's full industry chain advantage means ASEAN countries manufacturing cars will still require significant external supply. With the canal, this supply can come not just from China's coast but also from Guangxi and further inland, greatly promoting industrial synergy between China and ASEAN.
The canal is also expected to facilitate the implementation of RCEP and the China-ASEAN FTA 3.0. Liu Yunzhong points out that the zero-tariff benefits of RCEP require low-cost logistics to be fully realized. The canal lowers the threshold for cross-border bulk commodity trade, expands trade volumes, and will help refine the division of labor in industry chains and enhance supply chain resilience. At the canal's outlet, the China-Malaysia Qinzhou Industrial Park is adjusting its strategy towards ASEAN, aiming to upgrade cooperation with the Malaysia-China Kuantan Industrial Park through industrial linkage mechanisms, promoting bilateral investment in areas like auto parts, halal food, and palm oil processing. Seventeen Malaysian investment projects have already been established in the park.
With a total investment exceeding 72 billion yuan and three cascade shipping hubs, a simple calculation based on lockage fees (1 yuan per ton) suggests it would take over a century to recoup the investment. However, Wu Peng argues this is too narrow a view. The canal's purpose is to lower social logistics costs, saving an estimated 5 billion yuan annually through reduced freight. These savings are passed down through prices of raw materials, intermediate goods, and final products, ultimately benefiting consumers. Data indicates the project will directly drive approximately 180 billion yuan in GDP growth, create over 420,000 jobs during construction, and support 260,000 to 410,000 jobs during operation. The design team estimates annual GDP growth of 130 to 200 billion yuan along the route. "This isn't just about building a canal; it needs to drive other investments. It's a big and long-term calculation," Wu Peng concluded.
