United Nations (UN) Secretary General Antonio Guterres hailed Nairobi as a critical pillar of global multilateralism during the launch of a major expansion of its headquarters in Kenya.

• The expansion project, costing nearly USD 340 million (Ksh 44.2 billion), signifies a growing shift of global influence toward Africa.
• Key figures involved include UN Secretary General Antonio Guterres and the Kenyan government.
• The new office buildings are the UN's first net-zero facilities, powered entirely by on-site solar energy, with the goal of making the campus energy-neutral by 2030.
