The charity has shortlisted four agencies and says it plans to make a decision imminently.
A spokeswoman said: 'Comic Relief would like to work with an agency to promote our grants programme for UK-based diaspora organisations working in development in Africa.
'Meetings have already taken place with potential agencies and we are now at the decision-making stage.'
Diaspora organisations are run by people who define themselves as being of a certain heritage that they retain emotional, financial and cultural links with.
Examples of UK-based diaspora organisations currently funded by Comic Relief include the Promote Mifumi Project, Widows and Orphans International, and Africare.
Comic Relief has been speaking to agencies that specialise in dealing with the black and ethnic minority media.
The project will run for six months and Comic Relief describes it as having a 'very limited budget' to deliver a targeted campaign.
Comic Relief was recently the official partner of Africa United, a film that told the story of three Rwandan children and their bid to achieve their dream of taking part in the opening ceremony of the 2010 Football World Cup in Johannesburg.
