Why it matters

Forced the Simandou iron ore deal through: $20bn mine, 650km railway, Morebaya deep-water port; first shipment of 200,000 tonnes to China in early 2026.
Simandou: $20bn mine, 650km trans-Guinean railway, Morebaya port, 120Mt/yr capacity; sovereign wealth fund created; $200bn Simandou 2040 plan.
UN documented intimidation, politically-motivated enforced disappearances, and a climate of fear ahead of the 2025 vote; opposition figures exiled or jailed.
Positions Guinea as the resource-sovereignty success story — a junta that delivered the world's biggest mining project.
