On September 16, the Pinglu Canal was officially opened to navigation. This strategic waterway, stretching 134.2 kilometers with a total investment of approximately 72.7 billion yuan, begins at the Pingtang River estuary in the Xijin Reservoir area of Hengzhou, Nanning, flows south through Luwu Town in Lingshan County, Qinzhou, and follows the Qin River to the Beibu Gulf, accommodating vessels up to 5,000 tons.

With this development, the critical shortfall of Guangxi's inland waterways connecting directly to seaports has been addressed, freeing Nanning from its longstanding predicament of being "near the sea but unable to reach it" and transforming it into a bona fide coastal city. Some commentators suggest this long-overlooked western city has finally secured an opportunity to step into the spotlight. The benefits, however, extend far beyond Guangxi alone.

For years, the resource-rich and industrially robust hinterlands of southwest and south-central China have been constrained by a geographic bottleneck, where inland river shipping to the sea required detours of hundreds of kilometers through the Greater Bay Area, stifling the region's opening-up potential. The canal's commissioning fundamentally rewrites this scenario, slashing inland navigation distances for southwestern cargo by over 560 kilometers, with comprehensive logistics costs projected to drop by 18% to 30%, saving more than 5 billion yuan annually in social transport expenses. Beyond the southwest, provinces including Guangdong, Jiangsu, and Hainan are already sensing fresh opportunities for collaboration and competition, re-evaluating their own channel, port, and industrial layouts to seek points of integration.

As the provincial capital and the canal's starting point, Nanning stands as a direct beneficiary of this historic shift. Days before the canal's launch, Nanning Port welcomed its first international voyage vessel, marking a milestone where外贸 ships sailed directly from Beibu Gulf seaports to inland Nanning via the river. The leap from an inland city to a river-sea hub, as local media describe it, alters not merely logistics routes but also the city's centuries-old inland-oriented mindset. For a long time, Nanning was saddled with the label of a "weak capital"—less renowned than Guilin within Guangxi, less industrialized than Liuzhou, and lagging in national economic ranking. Now, favorable conditions to reshape its economic and industrial competitiveness are emerging. Estimates indicate that local enterprises shipping via the Pinglu Canal could reduce comprehensive logistics costs by 30% to 40%. For example, BYD's Nanning project, which currently imports hundreds of thousands of tons of spodumene annually, could save over 10 million yuan each year on freight alone if the cargo shifts entirely to the canal after arriving at Qinzhou Port, alongside savings of over 30 yuan per ton for bauxite and roughly 20% for grain containerization costs. As logistics connectivity expands across the southwest and broader hinterland, Nanning is poised to accelerate its role as a core hub in the New Western Land-Sea Corridor.

Industrial clustering effects are already visible. From January to July this year, the key implementation zones along the Pinglu Canal Economic Belt in Nanning signed 148 projects each exceeding 50 million yuan, spanning new energy and batteries, high-end equipment manufacturing like shipbuilding, forest product processing, and artificial intelligence. To precisely capitalize on these advantages, Nanning is rapidly building a canal-adapted industrial system with fresh objectives. It is promoting the "4+3+N" advanced manufacturing clusters toward sea-oriented development: cultivating four 100-billion-yuan clusters in new energy, AI and next-generation IT, non-ferrous metal deep processing and critical metal materials, and food processing; developing three 50-billion-yuan clusters in machinery and high-end equipment manufacturing, modern green chemicals, and forest product processing and papermaking; and fostering emerging and future industries such as low-altitude economy and biomanufacturing. The focus is on deep processing and export-oriented industries, integrating manufacturing with port logistics and cross-border trade to establish a key advanced manufacturing hub linking the Greater Bay Area and ASEAN.

In the national water transport landscape, the Pinglu Canal is a pivotal corridor capable of reshaping regional logistics frameworks. Beyond Guangxi, the most immediate beneficiaries are the southwest provinces. For instance, Sichuan's cargo previously had two main routes to sea: eastward along the Yangtze River for over 2,000 kilometers to Shanghai, or via rail-sea intermodal transport south to Beibu Gulf ports, both involving multiple transshipments, extended transit times, and high costs. With the canal operational, southwestern cargo can cut inland navigation distances by over 560 kilometers compared to traditional routes, significantly shortening voyages to major ASEAN ports—effectively granting the entire southwest a closer maritime gateway. Industrial products highly sensitive to logistics costs, such as chemical new materials and equipment manufacturing from Sichuan and Chongqing, green aluminum from Yunnan, photovoltaic products from Guizhou, and construction machinery from Hunan, can all leverage the canal to substantially reduce export shipping expenses. Tangible data supports this: Zhang Zhiwen, Deputy Secretary-General of the Guangxi Zhuang Autonomous Region government and its spokesperson, recently stated that comprehensive logistics costs for southwestern cargo via the Pinglu Canal would drop by 18% to 30%, saving society over 5 billion yuan annually.

Economist Zhang Yansheng told our publication that China's past opening-up was predominantly westward-facing, centered on the eastern coastal regions of the Pearl River Delta, Yangtze River Delta, and Beijing-Tianjin-Hebei. The relatively lagging openness of the west stems largely from persistently blocked sea access. As a key component of the New Western Land-Sea Corridor, the Pinglu Canal holds immense significance for the opening-up and development of the southwest, south-central, and northwest regions along its route. When viewed alongside the proposed Xianggui Canal and Zhe-Gan-Yue Canal, a water transport network featuring east-west complementarity and north-south connectivity is taking shape. Economist Pan Helin noted that this transforms the national waterway system from a pattern of "strong east-west, weak north-south" into a three-dimensional "interconnected network," prompting a redefinition of port functions nationwide. More regions are joining this collaborative wave. In Jiangsu, for example, local media envision that once the Pinglu and Xianggui canals are both operational, southwestern cargo could flow from Beibu Gulf through the Pinglu Canal into the Xijiang, then via the Xianggui Canal across watersheds into the Yangtze River system, reaching Jiangsu and radiating northward through the Beijing-Hangzhou Grand Canal—positioning Jiangsu as an unavoidable hub along this grand water artery. Meanwhile, Hainan, as an island economy with limited local cargo volumes and hinterland depth, could gain added economic reach if Yangpu's international shipping network and the Hainan Free Trade Port's institutional advantages are effectively linked with the southwest's industrial demands. Collaborative steps are already underway; in April this year, Hainan and Guangxi signed an agreement to build a "Yangpu Port–Beibu Gulf Port–Pinglu Canal" logistics corridor, jointly forging a frontier for opening-up cooperation with ASEAN.

The Pinglu Canal does more than establish a domestic north-south water logistics route; it serves as a fresh bond for deepening China's foreign trade and economic cooperation. Data shows that in 2025, China-ASEAN bilateral trade surpassed the $1 trillion milestone for the first time, reaching $1.05 trillion, a 7.4% year-on-year increase. Lei Xiaohua, Deputy Director of the Southeast Asia Research Institute at the Guangxi Academy of Social Sciences, previously noted that after crossing this threshold, bilateral trade would see another growth spurt, driven by the global economic center of gravity shifting eastward. Southeast Asia, riding an economic upswing, presents strong import demand from its growth, infrastructure, and consumer market expansion, naturally complementing China's production capacity. As the nearest maritime gateway from western China to ASEAN and a crucial hub port for the New Western Land-Sea Corridor, Beibu Gulf Port accelerated its development following the 2019 approval of the corridor's master plan. From 2020 to 2025, its container throughput maintained double-digit growth, ranking among the fastest-growing major coastal ports nationwide. Yet, compared to mature gateways, Beibu Gulf Port still lags in foreign trade scale. In 2025, its annual container throughput surpassed 10 million TEUs, but Shenzhen Port alone handled 33.156 million TEUs of foreign trade containers that same year. Now, leveraging the Pinglu Canal, Guangxi's freight sector is poised for another upgrade. Lei Xiaohua suggests the canal will reshape China-ASEAN trade transport organization models. Once liner routes mature, enterprises can expand procurement scales, generating stable trade orders, with bulk cargo benefiting first. Vietnam, Thailand, Malaysia, and Indonesia hold substantial cargo growth potential—commodities like Vietnamese wood chips, Thai rubber, and Malaysian palm oil could only form effective cargo flows by accessing the canal through Beibu Gulf Port. However, as Zhang Yansheng analyzed, compared to neighboring major ports, Beibu Gulf Port still faces significant gaps in logistics, transport, and warehousing that require gradual improvement. Furthermore, some experts point out that a core challenge post-launch is breaking path dependency in logistics; the traditional Pearl River Delta route via the Xijiang has entrenched interest structures and cost inertia. To attract ocean-going cargo back from Beibu Gulf Port, the Pinglu Canal must offer absolute advantages in comprehensive logistics costs, including transshipment and time losses. But this doesn't imply Beibu Gulf should vie for the same pie as major ports. In terms of port coordination, the cargo flows generated by the Pinglu Canal should be about diversion rather than substitution. Greater Bay Area ports, with mature ocean liner networks, refined port services, and a robust foreign trade ecosystem, remain China's core hubs for far-sea trade with Europe and America. Beibu Gulf Port, focusing on ASEAN near-sea trade, bulk cargo from the southwest hinterland, and river-sea intermodal operations, will form a differentiated, complementary development pattern with Greater Bay Area ports. As Zhang Yansheng puts it, connecting Guangxi's Beibu Gulf Port, Guangdong's Zhanjiang Port, and Hainan's Yangpu Port via the Pinglu Canal creates an interconnected port cluster, yielding greater collective benefits.
