China’s growing role in South America can be seen most clearly in the way it is reshaping the continent’s basic geography of trade and transport. Instead of relying on old, often inefficient routes that pass through third-party ports or require long detours, China is building and controlling new pathways that connect mines, farms, and industrial zones directly to the global market. These are not scattered projects but pieces of a carefully designed system: railways cut through soybean heartlands in Brazil, highways extend across mountain passes in Peru, and ports along both coasts are expanded or constructed to handle growing volumes of trade.
The centerpiece of this system is the deep-water port at Chancay, Peru. Unlike traditional ports that grew gradually over decades, Chancay was designed from the beginning to serve as a direct link between South America and China. Its infrastructure (specialized terminals, new access roads, and even tunnels that bypass urban bottlenecks) was built with one purpose: to reduce the time and cost of shipping goods across the Pacific. By eliminating the need for extra stops or transshipment through U.S. or European ports, Chancay strengthens China’s ability to secure a reliable, fast, and cost-effective flow of commodities.
The significance of these projects lies in what they create: path dependency. Once trade begins flowing through Chinese-built routes, it becomes difficult for countries to switch back to older ones. Infrastructure ties economies to specific corridors, and over time, these corridors shape both economic decisions and political choices. In short, China is reorganizing the map of South American trade in ways that lock in its influence for decades.
Securing Critical Resources via Targeted Investment
At the heart of China’s strategy is the need to guarantee access to the critical materials that feed its industries and energy transition. South America is home to some of the world’s most valuable reserves: copper from Chile and Peru, lithium from the “lithium triangle” of Argentina, Bolivia, and Chile, soybeans from Brazil, and hydrocarbons from Venezuela and Brazil. These are essential to China’s manufacturing base and its plans to dominate renewable energy and electric vehicle markets.
China’s method is not simply to buy these resources on global markets. Instead, it invests directly in mines, farms, and energy projects, often taking partial ownership or long-term contracts that guarantee a steady supply. For example, Chinese companies hold major stakes in lithium extraction firms and have invested heavily in copper mining.
The approach creates a relationship that is beneficial in the short term for South American states, which gain jobs, infrastructure, and tax revenue. But it also entrenches an element of asymmetry. South American economies become increasingly tied to Chinese demand, while China, in spreading its investments across multiple countries and commodities, insulates itself from local disruptions. If one supplier faces political instability, China can shift to another. The opposite is true of host countries, however, where dependence on Chinese demand and financing reduces their flexibility to diversify their economies or shift trade to alternative partners.
