Benin has appointed renowned American filmmaker Spike Lee and his wife, Tonya Lewis Lee, a seasoned producer and author, as its ambassadors for African-Americans in the US.

The couple are expected to serve as "thematic" ambassadors, raising awareness and supporting initiatives to promote Benin's ties with people of African descent.

The agreement was finalised during their visit to Cotonou, Benin's capital, last week, French public broadcaster RFI reports.

The government says it will help reconnect "people of African descent around the world to their historical, cultural, and spiritual roots".

The West African country also hopes the move will promote cultural tourism. It has come up with several initiatives encouraging people of African descent to reclaim their heritage and pursue citizenship where eligible.
