China’s US$10 billion Pinglu Canal will open in September and give southwest China a shorter water route to ASEAN
15 May 20264 min read
Summary
- Guangxi has brought forward the opening of the Pinglu Canal to the China-ASEAN Expo in September 2026, ahead of the original end-2026 completion date. It is China’s first river-to-sea canal built under national coordination since 1949.
- The 134.2-kilometre canal cuts the inland waterway route from southwest China to the sea by more than 560 kilometres, with official estimates of more than RMB 5 billion (about US$700 million) a year in transport savings.
- Yunnan and Guizhou already reach the Beibu Gulf by rail; the canal adds a southbound waterway for bulk cargo, giving ASEAN buyers who priced around Guangdong ports a second corridor.
Guangxi has brought forward the opening of the Pinglu Canal to the China-ASEAN Expo in Nanning in September 2026, ahead of the original end-2026 completion date, after Regional Chairman Wei Tao set the target at a site meeting on 25 February. The 134.2-kilometre canal links the Xijiang river system directly to the Beibu Gulf, the body of water bounded by China’s southern coast to the north and Vietnam to the west, and cuts the inland waterway route from southwest China to the sea by more than 560 kilometres compared with routing through Guangzhou.
The Pinglu Canal is the first river-to-sea canal built under national coordination since the founding of the People’s Republic in 1949. It runs from the Pingtang river mouth in the Xijin Reservoir on the Yu River in Hengzhou, Nanning, through Luwu in Lingshan county, and down the Qin River to the Beibu Gulf at Qinzhou, bypassing the Pearl River estuary and the Guangdong port corridor that has historically handled the bulk of southern China’s export cargo. Built to China’s Class I inland waterway standard, the highest in the country, it is designed for 5,000-tonne vessels. Three hubs at Madao, Qishi and Qingnian manage a total water-level difference of about 65 metres.
The project cost RMB 72.7 billion (about US$10.2 billion) and is one of the flagship investments under China’s strategy to develop Guangxi and Yunnan as gateways to ASEAN. Construction began in August 2022 on an approved 52-month schedule.
Guangxi government figures put the saving at more than RMB 5 billion (about US$700 million) a year in transport costs, with composite logistics costs 18 to 30 per cent lower than existing routes. The canal’s locks are designed for one-way throughput of 89 million tonnes a year. Official forecasts expect actual freight to reach 95.5 million tonnes by 2035 and 120 million tonnes by 2050.
Southwest China already reaches the Beibu Gulf by rail. Rail-sea services under the New Western Land-Sea Corridor cover 18 provinces and carried more than 500,000 twenty-foot equivalent units (TEU, the standard container measure) in 2025. What the canal adds is a southbound waterway, which matters most for low-value bulk where water freight undercuts rail. Guizhou holds some of China’s largest phosphate ore and bauxite reserves, and goods from southwest China have historically travelled more than 560 kilometres further by inland waterway to reach the sea through ports in Guangdong.
The September opening will be a ceremonial milestone rather than a commercial one. Volumes are likely to build gradually as shippers redirect existing flows, and the first meaningful throughput data should appear in 2027. Beibu Gulf Port, which covers Qinzhou, Fangchenggang and Beihai, passed 10 million TEU on 30 December 2025, up from 2.28 million in 2017, and now has annual container capacity of about 11 million TEU.
For supply chain operators in Vietnam, Malaysia and across the Gulf of Tonkin, the canal changes the freight options available to them. Commodities that previously moved via Guangdong, adding days and cost, gain a shorter sea corridor to ASEAN buyers, which affects landed costs for phosphate fertiliser, aluminium and agricultural products priced with a Guangdong premium. In the reverse direction, ASEAN exporters of rubber, rice and processed food gain a lower-cost route into China’s interior. Freight rates, port relationships and supplier pricing built around the Guangdong corridor are now open to renegotiation, a process that will run for years.

Correction, 23 September 2026: An earlier version of this article stated that the canal’s gravity wharf topped out on 30 April 2026; a wharf at the Qinzhou water service area topped out on 30 April 2025. It also misstated the vessel standard (5,000 tonnes, not 10,000), the source river (the Yu River, not the Qianjiang), the basis of the 89 million tonne figure, and said Yunnan and Guizhou would gain sea access for the first time. These have been corrected.
Correction, 24 September 2026: An earlier version of this article listed Yunnan and Guizhou commodities that no source supports. This has been corrected.
Update, 23 September 2026: The Pinglu Canal opened to navigation on 16 September 2026.
