On the morning of September 16, the Pinglu Canal, a key project of China's New Western Land-Sea Corridor, officially opened to navigation. Many might view this as just a piece of local news, but when you stretch the timeline back a hundred years and widen the perspective to the global trade chessboard, it becomes clear this could be a landmark event that reshapes China's urban landscape. Because of this canal, the increasingly massive industrial hinterland of central and western China is being reconnected to the Beibu Gulf, and from there to ASEAN and the global market. More importantly, this canal, which has been awaited for over a century, has finally found what it truly needed — cargo.
Dr. Sun Yat-sen envisioned this canal in his "International Development of China." Over the past hundred years, numerous feasibility studies were conducted, yet why was it repeatedly delayed? Beyond costs and technology, the fundamental issue was that the numbers didn't add up. In the past, the central and western regions simply didn't have enough freight to justify the massive investment. If cargo volumes weren't large enough, shipping via the Pearl River Delta was sufficient—why spend a fortune to cut a straighter path? For a century, the Pinglu Canal awaited one thing: the economic rise of central and western China. Now, that moment has arrived.
Because China's foreign trade landscape has been completely reshuffled. The first signal: the country that earns the most from American consumers has changed. From 2000 to 2025, China was the United States' largest source of trade deficit. But by the first half of this year, Vietnam had taken the top spot. The latest data shows Vietnam's foreign trade scale hit a new high from January to August. However, Vietnam hasn't truly replaced China's status as the world's factory. A significant portion of Vietnam's trade surplus with the US comes from Chinese enterprises, or Japanese and Korean companies that previously invested in China and then relocated. The industrial chains of these companies remain largely rooted in China. This creates an interesting phenomenon: Vietnam runs a huge surplus with the US but an even larger deficit with China. According to Vietnamese official data, in the first eight months, Vietnam's surplus with the US reached $106.6 billion, while its deficit with China hit $107.7 billion. Vietnam's purchases from China exceed what it sells to the US.
The second signal: domestic urban dynamics are shifting. Shanghai and Shenzhen—one is the main gateway for trade with Europe and America, the other for ASEAN trade. Since 2015, Shanghai has consistently held the top spot in national foreign trade. But in the last two years, Shanghai's trade figures have clearly been overtaken by Shenzhen. Different industrial tracks play a role, but the key factor is that China's imports and exports with the US are declining, while trade with ASEAN is surging. The wind is truly blowing westward. The center of foreign trade gravity is moving from the eastern US market to the southwest ASEAN market. Who is the hinterland closest to ASEAN? It's the central and western regions. In recent years, discussions about shifting from sea power to land power have seen the China-Europe Railway Express transform Sichuan and Chongqing into a westward-facing gateway, with cities like Chengdu gaining visibly more prominence. But don't forget, the Hengduan Mountains and the Qinghai-Tibet Plateau are immovable obstacles. Railways can be built toward Europe, but for ASEAN, maritime transport remains indispensable. Thus, the Pinglu Canal, spanning a century, has finally come into its own.
Rather than saying the canal's completion is merely an opportunity for the west, it's more accurate to say this is a mutually reinforcing outcome. Because industries in the central and western regions have grown, and because freight volumes to ASEAN have increased, the Pinglu Canal has arrived. Its opening to navigation will inevitably bring tremendous opportunities to cities within its sphere of influence. Who will benefit? Guangxi, undoubtedly—but many underestimate the extent of the gains. Over the past century, China's first-tier cities that have risen, aside from the capital's special status, all owe their success to locational advantages. Shanghai is a sea outlet with the massive Yangtze River inland waterway, radiating to a vast hinterland; Guangzhou has the Xijiang River waterway and its hinterland support; Shenzhen, adjacent to Hong Kong's major seaport, started with processing trade. Why has Guangxi, bordering Guangdong, lagged so far behind? Because although the Beibu Gulf faces the sea, it doesn't truly reach the ocean. Its outlet lies at the Pearl River Delta, over a thousand kilometers away. Now, with the Pinglu Canal open, based on historical experience and geographic location, Guangxi has completely acquired the energy foundation to nurture a new first-tier city.
The Pinglu Canal cuts the curve, making the region coastal and sea-reaching simultaneously. The waterway, ports, and hinterland have been artificially elevated to the same level as Shanghai and Guangzhou. And note: its navigational capacity is 5,000 tons. What does 5,000 tons mean? China's domestic inland waterways are classified into 7 grades, with Grade 1 being the best, and its standard is only 3,000 tons. Nationwide, Grade 1 waterways span just over 2,000 kilometers, accounting for barely 2% of navigable inland waterways. Both the Yangtze and the Pearl River have only one section classified as Grade 1. Yet the Pinglu Canal, a national project, has directly provided Guangxi with a 5,000-ton standard. In some ways, the Pinglu Canal has also equipped the Beibu Gulf with conditions similar to what Shenzhen had back in the day. Just a short distance from the Beibu Gulf lies Hainan's Yangpu Port. A free trade island with globally competitive tax and policy advantages, paired with a major deep-water port, combined with a 5,000-ton inland waterway and the entire central-western hinterland—large vessels could essentially sail freely between Hainan, the Beibu Gulf, and the Pinglu Canal. So, the Beibu Gulf can be said to hold a royal flush of cards.
For other parts of western China, the cards that Shanghai once brought to Jiangsu, Zhejiang, and Shanghai are now somewhat mirrored for them. According to estimates, cargo shipped via the Pinglu Canal reduces costs in Guangxi by up to 70%, in Yunnan and Guizhou by 39%, and in Sichuan and Chongqing by 9%. The era of the west may genuinely be dawning. And the emergence of another first-tier city in the Beibu Gulf region is not entirely beyond imagination.
