A continent-wide trade deal for Africa is a major step closer to being realised after 80 percent of African nations signed an agreement in the Rwanda capital Kigali on March 21. If ratified, the African Continental Free Trade Area (AfCFTA) will be the biggest free trade agreement since the creation of the World Trade Organization in 1995.Although regional economic powerhouses Nigeria and South Africa have so far withheld their signatures pending further domestic consultations, the margin of support for AfCFTA suggests the appetite for an Africa-wide trade bloc is at an all-time high.While there is pan-African support on paper, the challenges for making a trade deal work in practice are many. We'll examine who could win and who could lose under a continent-wide deal, and the prospects for a deal offering stability and security to all Africans.Subscribe to our channel http://bit.ly/AJSubscribeFollow us on Twitter https://twitter.com/AJEnglishFind us on Facebook https://www.facebook.com/aljazeeraCheck our website: http://www.aljazeera.com/
