Pinglu Canal Opens for Navigation, Rewiring Southwest China’s Trade Routes

The Pinglu Canal officially opened for navigation on September 16, 2026, completing a 134.2-kilometer waterway that gives China’s southwestern interior a direct river route to the sea for the first time. The canal, the backbone project of the New Western Land-Sea Corridor, was announced by Xinhua News, which confirmed the inauguration ceremony was held at the Madao hub in Qinzhou, Guangxi Zhuang Autonomous Region.

Built to Inland Waterway Grade I standard — the highest navigable classification in China — the canal can accommodate 5,000-ton-class vessels. It is the first canal constructed under national-level coordination to connect inland rivers to the sea since the founding of the People’s Republic in 1949.

Context: Solving a Geographic Mismatch

The canal answers a long-standing geographic problem. Southern China’s terrain slopes from northwest to southeast, and several major rivers cross Guangxi only to empty into the South China Sea through neighboring Guangdong. Despite being a coastal province, Guangxi lacked a direct navigable river-to-sea route — meaning, as one analysis put it, “Guangxi goods didn’t go through Guangxi ports.”

The Pinglu Canal starts at the Pingtang River mouth at the Xijin Reservoir area in Hengzhou City, Nanning, runs south through Luwu Town in Lingshan County, Qinzhou, and follows the Qin River into the Beibu Gulf. Construction began on August 28, 2022, and cost approximately 72.7 billion yuan (about RMB 540 million per kilometer), according to China News Service.

The Engineering Challenge

The canal’s defining difficulty was a roughly 65-meter difference between the water level at its starting point and the sea outlet. Engineers addressed this with three cascade ship-lock hubs — Madao, Qishi, and Qingnian — that operate like a series of “water elevators,” lifting or lowering vessels step by step.

A detailed CCTV feature published via Guangming Online outlined the technical milestones. The Madao hub, the upstream step with the largest drop — up to 29.6 meters — uses the world’s first three-tier stacked water-saving ship lock, described as the world’s largest inland water-saving lock, with a water-saving rate above 60 percent. The Qingnian hub, nearest the Beibu Gulf, employs China’s largest mutual-fill and discharge water-saving lock, at roughly 50 percent efficiency, and is the only hub directly handling the river-sea junction and anti-silt, anti-salt tasks.

According to China News Service, the project moved 315 million cubic meters of earth and stone — about three times the volume of the Three Gorges project — and involved 104 bridges, tens of thousands of construction workers, more than 160 research institutes, and over 800 academicians and experts. At the Madao hub, individual working valves weighing 70 tons each open in about one minute and close in 30 seconds, the report said.

Economic Impact and First Cargo

The canal is projected to shorten the inland waterway voyage for southwestern cargo by more than 560 kilometers compared with the traditional route through Guangzhou Port, cutting comprehensive logistics costs by 18 to 30 percent and saving society over RMB 5 billion in transport costs annually.

“The Pinglu Canal has opened a two-way ‘economic artery,’” said Wu Siyi, an associate professor at the Party School of the CPC Guangxi Committee, as quoted by China News Service. “The transport distance between China’s Southwest hinterland and ASEAN countries is shortened by more than 560 km, and logistics costs are reduced by 18 to 30 percent.”

The economic case has drawn industry attention. Nanning’s new-energy battery industry alone produces over RMB 130 billion in output value and requires large imports of spodumene, with canal-route shipping savings estimated at more than RMB 10 million per year. “Finished products such as batteries and copper foil produced in Nanning can also go directly through the canal to Qinzhou Port for export, and logistics costs for the ASEAN market will be significantly lower than the previous model,” Zeng Fanjun, general manager of the Guangxi Free Trade Zone Qinzhou Port Area Development and Investment Group, told China News Service.

Preparations for commercial service have been extensive. According to the CCTV feature, 570 vessels have obtained Pinglu Canal navigation qualification, and 681 crew members have received route endorsements. Ship lock passage fees have been temporarily waived from the opening date until the end of 2026. The first batch of foreign-trade cargo cleared customs by September 12 and departed September 16 aboard the first river-sea direct foreign-trade vessel, “Beigang Nanning Borun,” sailing from Nanning Port to Can Tho Port in Vietnam.

At Qinzhou Port, 13 river-sea intermodal berths have been adapted, adding roughly 32 million tons of intermodal capacity, including 800,000 TEU of container capacity.

Beyond Guangxi: A Regional and ASEAN Gateway

The benefits extend well past Guangxi. Yunnan’s agricultural products and green aluminum, Guizhou’s tea and solar products, Hunan’s engineering machinery and vehicle parts, and manufactures from Sichuan and Chongqing are all positioned to use the new route. On September 4, 2026, Sichuan’s first rail-river-sea train departed to send goods toward Vietnam via the canal.

Regional analysts estimate the annual transport savings for southwestern cargo routed to ASEAN could reach about RMB 5.2 billion. The canal’s designers frame it as establishing a new dual-direction sea-access pattern for Southwest China — “the East has the Yangtze, the South has the Canal.”

International observers see a connectivity opportunity. “The opening of the Pinglu Canal can create new opportunities for China-ASEAN connectivity,” Peng Somani, deputy head of the network television department at Cambodia’s national news agency, told the CCTV feature, expressing hope that Cambodian rice, fruits, and agricultural products can reach the Chinese market more efficiently. Zhang Aizhe, a host and reporter for Thailand’s PPTV, said Thai enterprises would take “a strong interest” in shipping goods to China via the canal.

Environmental and Tourism Dimensions

The project also incorporates ecological measures. At the Qingnian hub, engineers built a dual fishway with AI identification and sonar monitoring systems that has already recorded more than 200,000 fish passing through. A 240-meter-long, 20-meter-wide wildlife bridge — described as China’s first dedicated over-canal crossing for terrestrial animals — was completed upstream of the Madao hub to help local squirrels, wild boars, and leopard cats migrate. Near the Beibu Gulf outlet, mangrove restoration and migratory bird habitat protection have been carried out in parallel.

The canal is also being developed as a tourism route, with four sightseeing lines planned to showcase the project’s engineering, ecological, and cultural features — a line that its promoters say will let visitors travel “by boat from the inland river to see the sea.”

What’s Next

With navigation now open, attention turns to whether the projected cost savings and cargo volumes materialize. Ship lock fees are waived only through the end of 2026, and the canal’s longer-term value will depend on how quickly southwestern manufacturers reorient their supply chains toward the new route and how much ASEAN trade flows through Qinzhou Port. For a project four years and RMB 72.7 billion in the making, the opening is less an endpoint than the start of a test of whether a canal can genuinely reshape a region’s economic geography.
