Nigerian leaders continue to make their mark on the international stage, with key figures steering major diplomacy and development agendas across the globe. Prominent among them are Amina Mohammed and Ahunna Eziakonwa, two seasoned diplomats holding major offices within the United Nations, according to a report by Punch.
Amina Mohammed serves as the Deputy Secretary-General of the United Nations and chairs the UN Sustainable Development Group. UN Secretary-General António Guterres first named her to the post in December 2016, and she took office in February 2017. Her appointment made her the fifth person and the second African woman to hold the prestigious office, coming after Tanzania’s Asha-Rose Migiro. Guterres later renewed her mandate for a second term in January 2022.
In her position, Mohammed guides development coordination across 162 countries and territories. She joined the global body earlier in 2012 as Special Adviser to former UN Secretary-General Ban Ki-moon on post-2015 development planning. That assignment placed her at the forefront of consultations that produced the 2030 Agenda and the 17 Sustainable Development Goals adopted in 2015.
Before moving into international service, Mohammed served three Nigerian heads of state, Olusegun Obasanjo, Umaru Musa Yar’Adua, and Goodluck Jonathan, between 2000 and 2014. During this period, she coordinated debt-relief funding of roughly $1 billion per year targeted at Millennium Development Goals projects. She also served as Nigeria’s Minister of Environment from November 2015 to December 2016 under former President Muhammadu Buhari.
On the other hand, Ahunna Eziakonwa has dedicated nearly thirty years of service to the United Nations system. Guterres appointed her Under-Secretary-General and Special Adviser on Africa on June 12, 2026, and she took office on August 1, 2026, taking over from Cabo Verde's Cristina Duarte. In this capacity, Eziakonwa counsels the Secretary-General on African matters and strengthens ties between the UN and the African Union.
Her elevation followed her work as Assistant Secretary-General and Director of the UN Development Programme’s Regional Bureau for Africa, a position she assumed in August 2018. In that post, she managed development portfolios spanning 46 African nations, with earlier field postings taking her to Lesotho, Uganda, and Ethiopia.
