Chile is preparing to spend the next decade changing the balance of power in one of the world’s most important commodity markets.

The South American nation wants to attract approximately $100 billion in mining investment, increase its ability to refine copper at home, and build a broader international customer base. The plan is expensive, technically difficult, and likely to face aggressive competition from China.

It may also be one of the most consequential moves yet in the global struggle over critical minerals.

Chile is not trying to stop selling copper to China. Beijing is too large, too important, and too deeply connected to Chile’s economy for that. Instead, Chile wants to reduce the risk created by allowing one country to dominate both the buying and processing of its most valuable natural resource.

“The market is highly concentrated and we need to broaden the number of places that buy our copper,” Chilean Foreign Minister Francisco Pérez Mackenna said.

That is diplomatic language for a strategic problem. Chile produces an enormous share of the world’s copper, but China controls much of what happens to that copper after it leaves the ground.

Chile Produces the Metal, China Controls the Bottleneck

Chile produced 5.3 million tonnes of copper in 2025, approximately one quarter of global output. It is the world’s largest producer and a supplier that no major industrial economy can quickly replace.

China, however, consumes roughly 58 percent of the world’s copper and buys more than half of Chile’s copper exports. It has also built a massive smelting and refining industry that converts copper concentrate into usable refined metal.

That distinction is central to Chile’s plan.

During the period covered by Chilean central bank figures, the country exported $19.05 billion in copper concentrate. Of that amount, $11.63 billion went to China. Chile also exported $9.29 billion in refined copper, but the customer base was very different. The United States was the largest buyer, purchasing $5.25 billion, while China bought $1.16 billion.

Chile is therefore heavily dependent on China for sales of raw concentrate, while the United States is already its leading customer for higher-value refined copper.

This gives China influence over more than purchases. By controlling enormous refining capacity, Chinese companies occupy the critical middle section of the supply chain. They buy raw material, process it, and then help determine where the refined metal goes and how it is priced.

China’s power does not come from owning all the copper deposits. It comes from controlling the industrial system that turns ore into metal.

The $100 Billion Countermove

Chile wants to change that arrangement by refining more copper inside its own borders.

The proposed investment would support new mining capacity, processing infrastructure, smelters, refineries, and the supporting systems needed to ship more finished copper to buyers around the world.

“To do that, Chile needs to invest heavily so it can move away from exporting concentrate and instead start shipping refined copper,” Pérez Mackenna said.

The goal is not merely to produce more. It is to capture more of the value chain.

If Chile can process more of its own concentrate, it will no longer have to rely as heavily on Chinese smelters. It could sell refined copper directly to the United States, India, Europe, Japan, neighboring Latin American countries, and fast-growing Asian economies.

Chile has already begun negotiating a free trade agreement with India and is seeking stronger arrangements with regional partners. It is also exploring deeper relationships with Gulf states and Southeast Asian economies.

China would remain a major customer. Pérez Mackenna acknowledged that reality, saying, “Probably China will continue to be a very significant client for our copper because of the industrial footprint they have.”

The difference is that China would become one important customer among several, rather than the dominant gatekeeper.

Why the United States Needs Chilean Copper

For Washington, Chile’s proposal arrives at a critical moment.

Copper is essential to electrical grids, electric vehicles, data centers, artificial intelligence infrastructure, batteries, communications equipment, and modern weapons systems. The expansion of AI alone requires immense amounts of wiring, power transmission, cooling systems, and electrical equipment.

The United States wants more copper, but it faces a supply chain dominated by a strategic competitor. China controls more than half of global copper smelting capacity and operates four of the world’s five largest refining facilities.

Washington is attempting to rebuild domestic production through tariffs, public investment, faster permitting, and partnerships with foreign producers. Mitsubishi’s nearly $600 million investment in Arizona’s Copper World project shows how allied capital is already being directed toward new North American supply.

Chile offers something even larger: an established producer with massive reserves, functioning mines, significant refined exports, and a long history of commercial ties with the United States.

The United States is already the largest source of foreign direct investment in Chile, with a cumulative portfolio of $12.5 billion, compared with $4.6 billion from China. Much of the Chinese investment is concentrated in mining, but America has the deeper overall investment position.

A major expansion of Chilean refining could connect Chile’s mineral wealth with American capital, technology, energy demand, and industrial policy.

Copper Enters the Great Game

Chile’s proposal is part of a larger geopolitical contest spreading across Latin America, Africa, Asia, and the Middle East.

China has spent years financing mines, smelters, infrastructure, ports, and processing facilities. It has built influence not only by purchasing minerals but by controlling the systems that move, refine, and price them.

The United States and its allies are now responding. Washington is investing directly in mining companies, seeking mineral agreements with African governments, supporting domestic projects, and pressuring partners to limit Chinese involvement in sensitive infrastructure.

Chile has already felt that pressure. Disputes involving a proposed fibre-optic cable to Hong Kong, a Chinese-linked observatory, and other infrastructure projects have shown that commercial decisions can quickly become national security issues.

This places Chile in the position of a geopolitical swing state. It sells 37 percent of all its goods to China, including copper, lithium, lemons, and cherries. China also buys 70 percent of Chile’s lithium. At the same time, Chile considers the United States its most important strategic partner.

Chile cannot simply choose one side without accepting major economic costs.

Its best move is to create competition.

An Expensive Path Toward Strategic Freedom

The $100 billion program will not be cheap, easy, or guaranteed to succeed. Chinese smelters have enormous scale, established supply relationships, and the ability to compete aggressively on price.

Building new refining capacity also requires reliable energy, environmental approvals, skilled labor, infrastructure, and patient investment. Chile will need clear regulations and a national security screening system that protects strategic assets without frightening away foreign capital.

Yet the alternative is to remain dependent on a market in which China buys most of Chile’s concentrate and controls much of the processing capacity that gives the metal its final value.

Chile’s plan will not end Chinese influence over copper. China is too large a buyer and processor for that. It could, however, weaken China’s grip by creating a second major refining center tied to Western, Indian, and other Asian markets.

That would give Chile more customers, the United States a more secure source of refined copper, and the global market an alternative to Chinese processing.

In the new geopolitical great game, power belongs not only to the nations that possess valuable resources, but also to those that control how those resources are processed and sold.

Chile already has the copper. Its $100 billion gamble is an attempt to gain control over what happens next.
