Botswana has signed a series of agreements with Oman covering energy, mining, and infrastructure, as the Southern African nation accelerates efforts to reduce its heavy dependence on diamonds, which account for roughly a third of GDP. Key deals include a 500-megawatt solar photovoltaic plant with battery storage, a joint mineral exploration agreement covering copper, gold, graphite, and iron ore, and infrastructure improvements including fuel storage facilities at Namibia's port of Walvis Bay. The agreements, formalised by President Duma Boko and Omani Sultan Haitham bin Tariq, come amid falling diamond prices and growing competition from lab-grown stones, which have strained Botswana's public finances and prompted a recent downgrade of its sovereign credit rating.
