The amounts sovereign wealth funds invest in the poorest countries is tiny compared to their overall portfolio. In 2008 the head of the World Bank Robert Zollick was attempting to persuade sovereign wealth funds to invest just 1% of their assets in Africa. [1] Investment by SWFs in Africa is not all good. Sovereign wealth funds are guilty of bad behaviour in the developing world. Some government-backed firms from China and the Arab world (not all of the SWFs) have provided capital to maintain some of Africa’s worst rulers in power, in exchange for the opportunity to gain access to the natural resources of their misruled states. Sudan for example has sold 400,000 hectares to the United Arab Emirates. [2] This has allowed dictators to ignore the conditions (e.g. for political freedoms and economic reforms) attached to funding offered by western aid donors and international institutions such as the World Bank. It also contrasts sharply with the behaviour of western companies, who are led to act more responsibly by pressures from their own governments, investors and media.
