All eyes on Africa? I don't think some theoretical trade proposal will have huge impact on declining Africa. I am not dismissing the hope... I am just saying don't expect sudden economical miracle and improvement of Africa' standard of living. Like malizai pointed out, corruption is among thousands of factors that could ultimately lead to failure. If the world was serious about bringing peace and prosperity to Africa, they might have funded education, food supplies, agricultural improvement, and maintaining military presence all over Africa.
US spends billions of dollars in Iraq, Chinese "peacekeeping" forces in Africa' oil fields, allowing African warlords to trade diamond industries, spending billions of dollars to explore space when they could use those money to reform food supplies... and quite frankly, I don't think the world cares about Africa... as long as raw materials are coming to Western world.
So until this miracle happens, I rather have my eyes on starcraft II trailers instead...
