Nigeria has received more than $300m (£241m) that were stolen by the former military ruler, Sani Abacha.
The money was returned from the US and the British dependency of Jersey.
Under a repatriation agreement it is to be spent on infrastructure projects.
Gen Abacha ruled Nigeria from 1993 until his death in 1998.
The anti-corruption agency Transparency International estimates he stole as much as $5bn during his time in office.
Switzerland is believed to have returned around $1bn over the last decade.
