US cereal giant Kellogg announced earlier this week it has entered into a joint venture agreement to step up its presence in Africa. Kellogg has partnered with Tolaram Africa, the local arm of Singapore-based conglomerate Tolaram Group. While the deal will not provide an immediate lift for Kellogg's struggling sales, it positions the company for long-term growth in a region of increasing importance for consumer goods companies.
