In line with a report by Bloomberg, Okonjo-Iweala, who is running for the office of the director-general of the World Trade Organisation (WTO), took US citizenship in 2019.
Most of the candidates running for the office of the DG at WTO boast of dual citizenship, which experts say may boost their chances at getting the much-coveted job.
Jesús Seade Kuri is Mexican and Lebanese; Amina Mohamed serves as a minister in Kenya, but has Somali roots; Abdel-Hamid Mamdouh is both Swiss and Egyptian.
Okonjo-Iweala arrived in the US 47 years ago and worked there for more than 25 years without taking up the country’s citizenship.
