The Chang Jiang, known in English as the Yangtze River, is the economic backbone of China and the most heavily used inland waterway on Earth. Stretching 6,300 kilometers from the Tibetan Plateau to the East China Sea, it drains an area covering nearly 19% of China’s land while supporting roughly a third of the country’s population and generating about 40% of its GDP. Few rivers anywhere carry that concentration of economic, ecological, and cultural weight.
Economic Engine of Modern China
The Yangtze River Basin is home to some of China’s largest and most productive cities, including Shanghai, Wuhan, Chongqing, and Nanjing. As of 2010, the basin’s total population stood at 441 million people, about a third of China’s total, and the region produced 12.3 trillion yuan in economic output. Those numbers have only grown since. The corridor linking these cities along the river is sometimes called the Yangtze River Economic Belt, and it functions as the industrial and commercial core of the country.
Agriculture in the basin is equally significant. The warm, wet climate of the middle and lower Yangtze has sustained rice cultivation for thousands of years, making the region one of the most productive farming zones in Asia. The river also irrigates vast stretches of farmland and supplies drinking water to hundreds of millions of people.
The World’s Busiest Inland Waterway
The Yangtze handles more cargo than any other river system in the world. In 2024, ports along the main channel processed a record 4.02 billion tonnes of freight, the first time throughput crossed that threshold. That included 850 million tonnes of coal, 130 million tonnes of oil and gas, 110 million tonnes of grain, and over 26 million shipping container units. The 3.9% year-on-year growth in 2024 reinforced the river’s nickname as China’s “golden shipping route.”
Ocean-going vessels can navigate upstream as far as Wuhan, roughly 1,000 kilometers from the coast, while smaller barges push goods deep into China’s interior all the way to Chongqing. More than 160 bridges have been built or are under construction across the river, with 132 spanning the main channel as of late 2019. That infrastructure connects north and south China across what was historically one of the country’s biggest geographic divides.
Hydropower and Energy Production
The steep elevation drops along the upper Yangtze make it one of the most powerful sources of hydroelectric energy in the world. The Three Gorges Dam, completed in 2006, is the largest hydropower facility ever built. Over its lifetime, the project has generated more than 1.7 trillion kilowatt-hours of electricity, enough to power a mid-sized country for years. The dam also plays a role in flood control, moderating the seasonal surges that historically devastated downstream cities.
Several other major dams operate along the Yangtze and its tributaries, collectively forming a network that supplies clean energy to eastern China’s industrial centers. The tradeoff, however, has been significant: dam construction altered water flow, blocked fish migration routes, and reshaped the river’s ecology in ways that are still being measured.
Water Supply for Northern China
The Yangtze is the source river for one of the most ambitious infrastructure projects in history: the South-to-North Water Diversion Project. Northern China, including the Beijing region, faces chronic water shortages, and this system transfers Yangtze water northward through a network of canals and pipelines. Annual transfer volume has grown from about 2 billion cubic meters to 10 billion cubic meters, now serving 45 large and mid-sized cities and benefiting over 185 million people. Without the Yangtze’s surplus, large parts of northern China would face severe water crises.
Biodiversity Under Pressure
The Yangtze Basin supports roughly 4,300 known aquatic species, many of them found nowhere else on Earth. That richness is now under serious threat. An increasing proportion of those species is highly depleted or at risk of extinction, and several have already been lost. The baiji, or Yangtze River dolphin, is now considered probably extinct, making the Yangtze finless porpoise the last remaining cetacean in the river system. A 2017 population survey estimated just 1,012 finless porpoises surviving in the wild, split between the main river channel and two connected lakes: Poyang and Dongting. The species is classified as critically endangered.
Other iconic species face similar declines. The Chinese paddlefish, once one of the largest freshwater fish in the world, was declared extinct in 2022. Overfishing, pollution, shipping traffic, and dam construction have all contributed to the collapse of fish populations across the basin.
The 10-Year Fishing Ban
In January 2021, China launched an unprecedented conservation measure: a complete ban on fishing across the Yangtze’s main channel and key tributaries, set to last a full decade. The goal is to give depleted fish stocks and broader aquatic ecosystems time to recover. It’s one of the largest freshwater conservation efforts ever attempted, affecting hundreds of thousands of commercial fishers who were relocated to other jobs.
Early assessments are cautiously optimistic but realistic. Researchers estimate that the ban could lead to a recovery of about 30% of aquatic animal resources by the time it ends in 2031, potentially yielding fish catches of around 160,000 tonnes. The limitation is that overfishing was only one of several stressors. Pollution, habitat loss from dam construction, and sand mining continue to degrade the river, meaning the fishing ban alone won’t fully restore what’s been lost.
Cradle of Chinese Civilization
The Yangtze’s cultural importance runs as deep as its economic role. Archaeological evidence places organized rice farming along the river’s middle and lower reaches as far back as 7,000 years ago, making the Yangtze valley one of the earliest cradles of agriculture in human history. While the Yellow River to the north is traditionally called the “Mother River” of Chinese civilization, the Yangtze basin developed its own distinct cultures in parallel, contributing foundational advances in farming, pottery, and settlement.
The river has shaped Chinese literature, art, and philosophy for millennia. The Three Gorges region, with its dramatic cliffs and mist-shrouded passages, inspired some of the most celebrated poetry in the Chinese literary tradition. Cities along the Yangtze served as imperial capitals, trade hubs, and battlegrounds during pivotal moments in Chinese history. Even today, the river carries a symbolic weight in Chinese identity that goes well beyond its practical uses, often described simply as the “artery of China’s wealth.”
