World Bank calls on Botswana to make large mining contracts public

The World Bank on Thursday called on Botswana to make details of its large mining contracts with companies public to improve transparency in the diamond rich country's business dealings. Botswana earns 89% of its foreign exchange income and 30% of national revenues from mining, predominantly diamonds. It has various large-scale mining, sales and marketing contracts with Anglo American's diamond unit, De Beers.
