Mo Farah was among those attending a summit at Downing Street on Sunday afternoon.
Members of the UN and other international aid organisations, the European Union and the private sector met at what was called the "hunger summit".
The aim was to raise the profile of tackling hunger and malnutrition. The Mo Farah Foundation has been supporting initiatives in the Horn of Africa for a number of years.
David Cameron hopes the event will be part of the legacy of the London Olympics.
During a photo opportunity, Mo performed his signature move, 'the Mobot'.
