"By 2012, US oil imports from sub-Saharan Africa had declined by 59% from peaks only a few years earlier, compared to a less drastic 23% decline in overall US oil imports. Nowhere is this rapid shift felt more acutely than in Nigeria. In three years alone US crude oil imports from Nigeria have decreased by 75%, from nearly 359m barrels in 2010 to 87m in 2013. Based on the US
Energy Information Agency’s figures for the first quarter of 2014, US imports will drop by another 75% this year alone to about 22m barrels. Edward Morse, head of commodities research at Citigroup Global Markets, predicts that the US and Canada will completely cease importing crude oil from West Africa some time this year."

So by your logic, are there sanctions on all of West and Central Africa now?
