China–DRC Trade: How China Pays for Congo's Cobalt and Copper ($25.9B)

China pays for Congo's cobalt and copper two different ways at once, and that split is the answer almost no source gives. Some of the trade — $25.9 billion in 2024, with Chinese firms controlling roughly 80% of Congo's cobalt output — never touches a bank wire: it settles in roads, dams, and loans under a barter-style "resource-for-infrastructure" model. The rest is ordinary spot trade that still needs US dollars, cleared on the same slow, expensive correspondent-banking rails that strain across the rest of Sub-Saharan Africa.

The headline figures above are well documented. What gets skipped is the part that matters to anyone moving money: how the trade is actually paid. As of June 2026, this page answers exactly that — separating the infrastructure-for-minerals barter from the dollar-settled cash leg, with every figure dated and sourced below.

How much do China and the DRC trade?

China–DRC trade reached about $25.9 billion in 2024, up roughly 38% year-on-year, making the DRC one of China's largest commodity suppliers in Africa, per SAIS-CARI's China–Africa trade dataset and Chinese customs (GACC) figures. The trade is overwhelmingly one metal-heavy direction: copper dominates, with cobalt a smaller but strategically critical share.

On the most-cited breakdown, refined copper accounts for roughly $19.5 billion of Congo's exports to China and cobalt for about $3.05 billion (Observatory of Economic Complexity, 2024 trade data). The relationship is lopsided: the DRC ships far more to China than it buys back. The OEC puts Congo's exports to China near $21.6 billion for 2024; against that, directional estimates of Chinese goods flowing the other way sit around $4.33 billion — we flag the import leg as less firm than the headline total, since source estimates of it vary. The numbers to anchor on are the $25.9B total (+38%) and the copper/cobalt breakdown.

China has been Africa's largest trading partner for 16 straight years, and across the continent that trade hit a record $348.05 billion in 2025, up 17.7%, according to GACC figures reported via Ecofin Agency. The DRC sits firmly inside the commodity-supplier half of that corridor — the countries where China runs a trade deficit because it buys raw materials it can't source at home.

How much of the world's cobalt does China control through the DRC?

Chinese firms control roughly 80% of the DRC's cobalt output — the metal at the heart of lithium-ion EV batteries — owning the mines, refining the metal, and selling it on, according to the US Army War College's Strategic Studies Institute (October 2024). The DRC supplies the majority of the world's mined cobalt, so control of Congo's output translates into control of a large share of the global supply chain for battery materials.

That concentration is why the trade matters far beyond bilateral statistics. Chinese firms own or hold major stakes in many of the DRC's largest copper-cobalt operations, and the refined metal feeds China's dominant position in battery and EV manufacturing. For Congo, it means a single buyer accounts for an enormous slice of mineral revenue — and that revenue depends on how those sales are structured and settled.

What is the Sicomines resource-for-infrastructure deal?

Sicomines is a resource-for-infrastructure (RFI) arrangement: a barter-style model in which Chinese state-linked firms build infrastructure — roads, dams, hospitals — in exchange for mining rights and a share of future mineral output, rather than paying cash up front. The framework agreement was signed in 2008 (following a 2007 protocol) and has been revised since, and it is the canonical example of how China finances access to Congo's copper and cobalt without a conventional purchase-and-pay transaction. The mechanism and its terms are documented in detail by AidData, which tracks Chinese development finance.

Resource-for-infrastructure (RFI): a financing model where a lender (typically a Chinese policy bank or state-owned enterprise) funds and builds infrastructure, and is repaid in mineral output or mining revenues rather than cash. The "payment" for the resource is the infrastructure itself — settlement happens in assets, not bank transfers.

The point that gets lost is what this does to the money trail. In a pure RFI deal, large volumes of copper and cobalt change hands with very little cross-border cash settlement, because the value is offset against construction costs and loans. That is genuinely different from a normal commodity export, and it shapes how the rest of the trade has to be paid.

How does China actually pay for Congo's cobalt and copper?

It runs on a split model. Resource-for-infrastructure deals like Sicomines settle in built assets and loans — barter, not bank wires — while spot sales of copper and cobalt outside those deals still settle in US dollars through correspondent banks. This RFI-versus-cash distinction is the part every academic and policy source skips, and it is the whole answer to "how does China pay for Congo cobalt."

Two payment worlds run in parallel:

• The RFI / barter leg. Under Sicomines and similar arrangements, Chinese firms recoup their investment by taking mineral output or mining profits. Little cross-border cash moves; the "payment" is the infrastructure already on the ground and the loans being amortised against production, as AidData's financing records describe. This insulates a chunk of the trade from currency markets entirely.
• The dollar-settled spot leg. Mineral sales that fall outside RFI structures — and the many smaller traders, processors, and service suppliers in the supply chain — still price and settle in US dollars. Like the rest of African commodity trade, that cash leg clears through correspondent banks, with all the friction that implies.

So the honest answer is not "China pays in infrastructure" or "China pays in dollars" — it is both, depending on the deal. The barter model handles the marquee, state-to-state portion. The dollar still does the everyday work, and it is the dollar leg that hits the bottleneck.

Why does the cash portion of DRC trade hit the dollar bottleneck?

Because the spot, dollar-settled leg depends on correspondent banking — and those rails into Central Africa are thinning, slow, and expensive. Sub-Saharan Africa is the costliest region in the world to move money: it costs 8.4–8.78% to send $200, versus a 6.49% global average and the G20's 3% target, per the World Bank's Remittance Prices Worldwide data. For a continent whose exports are priced in dollars, that is a structural tax on every cash transaction.

The plumbing is also disappearing. Global banks cut 127 African correspondent-banking relationships in 2024–25, and the stock of USD correspondent relationships in Africa has fallen more than 25% since 2011, according to Financial Stability Board data. When a correspondent relationship is severed, payments don't just get pricier — they reroute through more intermediaries, each adding a day and a fee. Correspondent settlement typically runs 3–5, and up to 7, business days, and only about 24.7% of Sub-Saharan African payments clear within an hour — among the slowest in the world, per the FSB's cross-border payment KPIs.

For a Congolese trader or a supplier into the mining economy, that means working capital sits in transit while ore waits. The RFI deals sidestep this; the cash economy can't.

What does the DRC import from China in return?

Mining vehicles, trucks, and heavy machinery — the manufactured inputs that keep the copper and cobalt operations producing. China's exports to the DRC, estimated near $4.33 billion in 2024 (directional estimate; treat the import-leg split as less firm than the $25.9B total), are concentrated in capital equipment rather than consumer goods, which fits a trade relationship built around extraction.

This is the import leg that most needs functioning dollar payments. A mine operator buying excavators or haul trucks from a Chinese supplier has to source USD and remit it through the same correspondent rails described above — and a multi-day, multi-percent settlement on big-ticket capital goods is exactly where the friction bites. It is also where the parallel between Congo and other resource exporters is clearest: the headline barter deals get the attention, but the day-to-day machinery trade runs on ordinary, dollar-hungry banking.

How could faster settlement change resource-trade payments?

Within the $25.9 billion China–DRC trade, the resource-for-infrastructure barter leg settles in roads and dams and never touches a bank wire — but the spot-and-machinery cash leg still needs dollars, and that part can now settle in seconds at up to roughly 90% lower cost using Treasury-backed stablecoins: digital dollars pegged 1:1 to the US dollar and backed by US Treasuries and cash held in reserve. This is settlement infrastructure, not speculative crypto; it moves a dollar from A to B without the multi-day correspondent chain.

The shift is already large. B2B stablecoin payments reached $226 billion globally in 2025, up 733% year-on-year, according to McKinsey's analysis with Artemis — the signal that this is corporate settlement, not speculation. None of this touches the RFI / barter portion of Congo's trade — that settles in infrastructure regardless. What changes is the spot-and-machinery leg, where a supplier waiting 3–5 days for a dollar payment can instead be paid the same day.

For the renminbi question on resource trade specifically — whether yuan, not dollars, is starting to settle these flows — the disciplined verdict lives in our CIPS reality check on whether the renminbi settles China–Africa trade: RMB flows are rising fast, but the dollar still settles the majority.

How Artoh helps when the dollar leg of resource trade stalls

The barter half of Congo's mineral trade takes care of itself. The dollar half — spot sales, machinery imports, the long tail of suppliers into the mining economy — is where money gets stuck: 8%-plus to move it, 3–5 days to clear it, and a shrinking set of correspondent banks willing to carry it.

Artoh is built for that leg. We give businesses across Africa and Latin America access to USD liquidity and Treasury-backed stablecoin settlement — digital dollars backed 1:1 by US Treasuries and cash, moved through licensed, compliant channels with a full audit trail. That lets a supplier or importer settle the dollar side of a trade in seconds rather than days, without waiting on a correspondent chain, and without the multi-percent cost stacked into every transfer. It is settlement infrastructure for real trade, not speculation.

If your business moves money into or out of a dollar-short market and the wait is costing you working capital, let's talk.
