Zambia's economy showed resilience in recent years, with strong GDP growth driven primarily by mining, particularly copper, which is Zambia's key export. Growing demand for minerals and Zambia's young, fast growing population are expected to support the country's medium term growth, although poverty remains very high. The government has focused on economic diversification, investing in agriculture and renewable energy. Recent progress on debt restructuring with internatinoal lenders is positive, but longer term debt sustainability remains a significant issue for the country.
