China’s Pinglu Canal Opens New Trade Route to Vietnam: What Businesses Should Know

China’s new Pinglu Canal has established a direct river-sea freight connection with Vietnam’s Mekong Delta. With the first Nanning–Can Tho container service now completed, businesses trading between Vietnam and southwestern China have a new logistics option to assess for sourcing, exports, distribution, and investment planning.

The first container vessel travelling from China’s Nanning Port through the newly opened Pinglu Canal arrived at Can Tho’s Cai Cui Port on 24 September 2026, marking the launch of a new maritime connection between southwestern China and Vietnam’s Mekong Delta.

The vessel departed Nanning on 16 September, travelling through the Pinglu Canal to the Gulf of Tonkin before continuing by sea and entering Vietnam through the Hau River.

The new service is initially expected to operate twice a month, with a voyage of around seven days. River-sea vessels operating the route can carry approximately 500 twenty-foot equivalent units (TEUs), with refrigerated containers expected to account for around 25 percent of capacity.

For exporters, manufacturers, and logistics companies, the development raises a practical question: could the new corridor reduce the cost or complexity of moving goods between China’s southwestern industrial regions and southern Vietnam?

What does the Pinglu Canal change for Vietnam–China trade?

China officially opened the Pinglu Canal on 16 September 2026. The RMB 72.7 billion (US$10.75 billion), 134.2-kilometre waterway connects Guangxi’s inland waterways with the Beibu Gulf, internationally known as the Gulf of Tonkin.

Designed for vessels of up to 5,000 tonnes, it provides inland areas of southwestern China with a more direct route to the sea. Previously, cargo using the inland waterway network could travel east through the Xijiang River system towards Guangdong. The new route shortens the inland waterway journey to the sea by more than 560 kilometres for relevant cargo originating in southwestern China.

For Vietnam, however, the most significant development is not the canal itself but the new transport connections it enables.

The Nanning–Can Tho service provides a direct river-sea connection between Guangxi and the Mekong Delta. Can Tho Port JSC and China’s Beibu Gulf Port Group are developing the service alongside logistics companies, shippers, and other supply-chain partners.

A shorter route does not automatically mean lower costs for every business. The commercial case will depend on freight rates, cargo origin, destination, shipment volumes, sailing frequency, port handling, customs procedures, and onward transportation.

Why Can Tho and the Mekong Delta matter

The route could be particularly relevant to Vietnam’s agricultural and food-processing industries.

The Mekong Delta produces significant volumes of rice, seafood, fruit, and processed agricultural goods. The planned allocation of around one-quarter of vessel capacity to refrigerated containers indicates that cold-chain cargo is expected to form an important part of the service.

This could give exporters another option for reaching China, including markets beyond its coastal regions.

China’s southwestern hinterland includes major population and industrial centres in Guangxi and neighbouring provinces and municipalities. The Pinglu Canal is also intended to attract cargo from locations including Yunnan, Guizhou, Sichuan, and Chongqing into the Beibu Gulf transport network.

Vietnamese companies are already examining this opportunity.

Vietnamese coffee producer Trung Nguyen Legend, which is expanding its retail presence in China, told the South China Morning Post that logistics had become a constraint as its Chinese operations grew. Its coffee beans are sourced from Vietnam, while existing road and maritime arrangements can involve circuitous routes and delays. The company is consequently assessing whether the Pinglu Canal could provide a more efficient connection with the Chinese market.

The opportunity extends beyond agriculture. Exporters of processed foods and other consumer products could examine whether the corridor improves access to inland Chinese distribution networks, while logistics companies may find new demand for consolidation, warehousing, customs support, and cold-chain services.

The opportunity also works in the opposite direction

The new corridor is a two-way trade route.

Southwestern China is a major manufacturing base, and improved access to the Gulf of Tonkin could make it easier to transport machinery, automotive components, chemicals, construction materials, and intermediate goods into ASEAN markets.

That has implications for manufacturers operating in Vietnam.

Businesses sourcing equipment, components, or raw materials from China should examine whether suppliers located in areas served by the new corridor could gain a more efficient route to southern Vietnam.

For companies considering new production or distribution facilities in the Mekong Delta, this could also become one factor in site-selection decisions alongside labour availability, industrial infrastructure, customer proximity, utilities, and access to domestic and international transport networks.

However, the benefits will depend on establishing sufficient cargo volumes in both directions.

Can Tho authorities have highlighted balanced two-way cargo flows as important to maintaining stable sailing schedules and creating scope for lower transport costs. With only two sailings per month planned initially, service frequency will be an important consideration for businesses with time-sensitive inventory requirements.

Could cheaper logistics also increase competitive pressure?

Businesses should also consider the competitive implications.

The Pinglu Canal is intended to facilitate two-way China–ASEAN trade, but lower transport costs could also make Chinese manufactured products more competitive in Southeast Asian markets.

This issue is already being discussed elsewhere in ASEAN. Businesses in the region have welcomed the prospect of improved access to Chinese consumers but also raise concerns that the canal could facilitate greater flows of competitively priced Chinese manufactured goods into Southeast Asia.

For Vietnam, the implications will differ by sector.

Manufacturers reliant on Chinese machinery and intermediate goods could benefit from more efficient sourcing. At the same time, Vietnamese producers competing directly with imported Chinese products may face additional pricing pressure if the corridor lowers transport costs and improves delivery times.

Companies should therefore assess the canal from both sides of their operating model: what could it do to input costs, and what could it do to competition in their end market?

Pinglu Canal–Can Tho Route: Key Considerations for Businesses
Business profile	Potential impact	What to assess
Mekong Delta agricultural exporter	Alternative route into Chinese markets	Freight rates, cold-chain capacity, customs, and market access
Food and seafood processor	Refrigerated container capacity	Sailing frequency, consolidation volumes, and delivery times
Vietnam manufacturer	Alternative sourcing channel from southwestern China	Total landed cost, supplier location, and inventory requirements
Chinese investor in Vietnam	Improved connection between Chinese suppliers and southern Vietnam	Production location, sourcing model, and distribution network
Logistics or warehouse operator	Potential new freight and consolidation demand	Cargo volumes, port connectivity, warehousing, and cold-chain requirements

What should businesses assess before changing their supply chains?

The arrival of the first Nanning–Can Tho vessel establishes that the corridor is operational, but businesses should avoid restructuring supply chains based on headline distance or projected cost savings alone.

Companies should compare the new route with existing road, rail, and maritime arrangements using total landed cost, transit time, sailing frequency, reliability, inventory requirements, customs procedures, and last-mile transport.

Exporters should also review product-specific Chinese market-access requirements. For agricultural and food products, improved transport does not remove requirements relating to customs registration, food safety, phytosanitary controls, labelling, or cold-chain management.

Manufacturers sourcing from China should map supplier locations against the new corridor to determine whether the route genuinely improves their logistics economics.

Finally, investors considering manufacturing, processing, warehousing, or distribution facilities in southern Vietnam should incorporate emerging connectivity into location analysis without assuming that current service levels will immediately support high-volume or time-sensitive operations.
