China-Guinea Trade Is a Story of Bauxite and Iron

In China’s trade with Guinea, almost everything comes down to two minerals: bauxite and iron. From January to July 2026, bilateral trade reached $12.1 billion, but the balance was overwhelmingly shaped by Chinese demand for Guinean raw materials. China exported $4 billion worth of goods to Guinea during the period, while importing $8.1 billion from Guinea, most of it bauxite.

In this sense, China’s relationship with Guinea is similar to its relationship with the Democratic Republic of Congo, where DRC exports of copper and cobalt dominate trade. In Guinea, bauxite and iron play the same role, but the concentration is even more extreme. Guinea’s exports to China are not just mineral-heavy; they are almost entirely built around bauxite, with iron ore now rising fast as the Simandou project enters production.

The top 10 Guinean exports to China show just how concentrated the relationship is. The first item, bauxite, accounts for almost all export value, while the next three lines are different customs categories of iron ore:

1. Aluminum ore, bauxite: $7.38 billion
2. Iron ore, non-agglomerated: $512.4 million
3. Iron ore, non-agglomerated, second subcategory: $122.1 million
4. Iron ore, non-agglomerated, third subcategory: $70.8 million
5. Refined copper-based products, unwrought, n.e.s.: $13.8 million
6. Copper-zinc alloys, brass, unwrought: $1.08 million
7. Granite, roughly cut into blocks or slabs: $552,623
8. Copper anodes, for electrolytic refining: $323,925
9. Aluminum, unwrought, alloyed: $76,164
10. Nickel ores and concentrates: $22,533

Even more than the DRC, Guinea is almost a single-product exporter. Bauxite, the ore used to produce aluminum, accounts for virtually all of its trade with China. On its own, it represents about $7.38 billion, or more than 90% of the top 10.

If the three iron ore categories are added, worth about $705 million in total, bauxite and iron ore together account for almost 100% of Chinese imports from Guinea. Everything else is essentially a rounding error, ranging from a few hundred thousand dollars to a few million — negligible in the bigger picture.

The difference with the DRC is not only the level of concentration, but also the level of processing. The DRC exports much of its copper to China as copper cathode, a refined product that is 99.99% pure metal. Guinea, by contrast, still exports bauxite largely as raw ore, despite the government’s push to develop more processing capacity at home.

Comparison Between the DRC and Guinea

This partly explains the Guinean government’s decision to introduce quotas on bauxite exports. Export volumes will depend on whether mining companies comply with their commitments to build alumina processing plants inside the country. In May 2026, Chinese company Chalco announced plans to invest $1 billion in the construction of an aluminum refining plant.

Guinea wants to reach domestic aluminum refining capacity of about 6 million tonnes by 2030, rather than simply continue exporting raw ore.

The quota measure, announced for April 2026, still had not entered into force by August 2026. The decree that would formalize it is still pending.

The monthly data for bauxite exports show a sharp spike in May, when China’s imports from Guinea reached 19.6 million tonnes, before falling back to 15.89 million tonnes in June and 14.9 million tonnes in July, roughly where they had been in January. The May spike likely reflects front-loading ahead of Guinea’s expected export quota policy.

The decline in June and July do not reflect a collapse in demand, but rather a return to more normal shipment levels, shaped by policy uncertainty, higher freight costs, and seasonal disruptions. Even with the dip, the January-July total still shows how central Guinean bauxite remains to China’s aluminum supply chain.

The delay in implementing the quota underscores the tension in Guinea’s mining policy. Conakry wants to push companies toward local processing, but it also benefits from the continued growth of raw bauxite exports.

As long as demand from China remains strong, exports will keep rising. The question is whether Guinea can move from announcing industrial ambitions to enforcing them in a sector where Chinese demand is already driving record trade.

As for iron, Guinea’s second-largest export to China, the trend has been upward throughout the year. This increase is explained by the start of production at the Simandou mine, which has already made several deliveries to China, including its largest shipment, of 2 million tonnes, in May 2026. Iron exports increased almost ninefold between January and July 2026. These figures can be expected to continue rising throughout 2026.

The rise of iron ore exports could gradually change the structure of China-Guinea trade. For now, bauxite still dominates almost everything, but Simandou gives Guinea a second major export pillar and could make the relationship less dependent on a single mineral. If that happens, China-Guinea trade may become less of a one-mineral story, even if it remains overwhelmingly extractive.
