The Black Cats will wear the name of the organisation on their shirts for at least the next two seasons.
They include Ghanaian trio Asamoah Gyan, John Mensah and Sulley Muntari.
Egypt international Ahmed Elmohamady and last season's club player of the year, Benin midfielder Stephane Sessegnon, are current members of the Black Cats squad.
The club also signed a partnership agreement with Ghanaian side Asante Kotoko last year, which saw them offer practical support and advice in youth coaching to the Kumasi-based club.
"It truly gives something back to both our own region and to a continent which has become a firm part of our club's success story over recent seasons."
"Both places are renowned for examples of how football can engage people and organisations to the extent where it changes lives."
