Nigerian President Goodluck Jonathan appointed outgoing finance minister and former Goldman Sachs executive Olusegun Aganga as the new trade and investment minister on Monday, according to Reuters. Jonathan was sworn in for his first full term on May 29 following an election and his ministerial choices are being closely watched by Nigerians and foreign investors keen for a team capable of driving badly needed reforms. Ngozi Okonjo-Iweala resigned on Friday as managing director of the World Bank in order to become Nigeria's new finance minister, spurring hopes of reform in sub-Saharan Africa's second biggest economy.
