Over the past eighteen years, closely following the evolution of economic relations between Brazil and China, both in academia and in the financial sector, I have observed a subtle transformation that still receives far less attention than it deserves.
Much of the analysis surrounding Sino-Brazilian relations remains centred on traditional trade flows. The discussion typically revolves around soybeans, iron ore, beef exports, or successive records in bilateral trade volumes.
These elements remain fundamental. Yet they are no longer sufficient to explain the strategic depth that has come to characterise the relationship between the two economies.
My assessment today is that Brazil and China are entering a new phase of engagement. A phase in which food security will remain important, but will no longer constitute the sole pillar of the partnership. The strategic axis is gradually shifting towards infrastructure, energy, technology, logistics and critical minerals.
This transformation is not occurring by chance.
China understood, perhaps earlier than most Western economies, that the twenty-first century would be defined by technological innovation as well as by the ability to secure reliable access to food, energy, logistics and critical resources. In an international environment increasingly marked by geopolitical tensions, trade disputes and the restructuring of global supply chains, security has become an economic asset as valuable as efficiency itself.
Within this context, Brazil occupies a uniquely advantageous position.
Few nations combine continental scale, abundant natural resources, global agricultural leadership, a relatively clean energy matrix, geopolitical stability and substantial productive expansion potential. This combination grants Brazil a strategic relevance that extends far beyond its role as a commodity exporter.
The numbers help illustrate the scale of this reality.
Bilateral trade between Brazil and China reached approximately US$171 billion in 2025, consolidating China’s position as Brazil’s largest trading partner and accounting for more than a quarter of the country’s total foreign trade. More than a commercial statistic, this figure reflects a level of structural economic integration that can scarcely be regarded as temporary or circumstantial.
Yet it is beyond trade where I perceive the most significant transformation taking place.
China has steadily directed investment towards strategic sectors of the Brazilian economy. Renewable energy, logistics infrastructure, electric mobility, technology and mining have assumed a progressively larger role in the bilateral agenda.
In 2025, Brazil became the leading destination for Chinese outbound investment, attracting approximately US$6 billion in new projects. This is not merely capital seeking financial returns. It represents investment associated with long-term strategic interests.
It is at this point that copper emerges as a central protagonist.
Frequently treated as just another mineral commodity, copper has become one of the most strategic resources of the contemporary economy. The expansion of electric vehicles, energy storage systems, transmission networks, wind farms, solar installations and the data centres required to support the advancement of artificial intelligence is generating a structural increase in global demand for the metal.
I have consistently argued that copper may play, in the electrified economy of the twenty-first century, a role comparable to that played by oil in the industrial economy of the twentieth century.
This is not rhetorical exaggeration.
Without copper, large-scale electrification is impossible. Without copper, there can be no meaningful energy transition. Without copper, there is no dependable infrastructure capable of sustaining the expansion of artificial intelligence.
Brazil possesses significant copper reserves and considerable untapped potential when compared with other major mining economies. More importantly, however, the country benefits from a rare combination of strategic minerals.
According to data from the Geological Survey of Brazil and international institutions, Brazil holds approximately 23 per cent of the world’s rare earth reserves, placing it among the nations with the largest known deposits of these essential minerals. Rare earth elements are indispensable for semiconductors, batteries, electric motors, advanced defence systems and a wide range of high-technology applications.
There is, however, a paradox that deserves careful reflection.
Although Brazil possesses one of the largest rare earth endowments on the planet, it still plays only a modest role in global production and processing. In other words, the country has already become a geological power, yet it has not fully established itself as an industrial and technological power associated with these resources.
This may well constitute one of Brazil’s greatest economic challenges over the coming decades.
The opportunity lies not merely in extracting minerals.
The real opportunity lies in developing the technological, industrial and financial capabilities required to transform these resources into innovation, productivity gains, highly skilled employment and sustainable economic growth.
From China’s perspective, this agenda is of profound strategic importance.
China requires secure access to food, energy and critical minerals. Brazil requires investment, technology, infrastructure and greater productive sophistication.
There exists a structural complementarity between these needs that transcends governments, political cycles and temporary economic fluctuations.
For this reason, I believe it is a mistake to interpret the Brazil’China relationship exclusively through ideological lenses.
Enduring economic partnerships are built upon national interests, not transient political narratives.
The true challenge for Brazil is to recognise the magnitude of the opportunity before it.
No nation achieves sustainable prominence by limiting itself to the export of primary products. The next stage of the Sino-Brazilian partnership will require value-added production, technological innovation, legal certainty, regulatory stability and a genuine long-term strategic vision.
The central question is not whether the relationship between Brazil and China will continue to grow.
In my view, that trajectory is already firmly established.
The more relevant question is whether Brazil will be able to transform this relationship into a platform capable of accelerating its own economic and technological development.
For this reason, I believe that the evolution of the Brazil’China partnership can be symbolically represented by the transition from soybeans to copper.
Not because one replaces the other.
But because together they reveal something far more significant, the transformation of a predominantly commercial relationship into an increasingly strategic partnership, one that may help shape the emerging economic geography of the twenty-first century.
