Nigeria will consider the interests of its industries in deciding whether to sign up to a $3-trillion Africa free-trade agreement, President Muhammadu Buhari said in a meeting with local manufacturers on Wednesday. The African Continental Free Trade Agreement (AfCFTA) encompasses 1.2-billion people. Fifty-two of the 55 countries that make up the African Union (AU) have now signed. Aside from Nigeria, only Benin and Eritrea have opted not to sign up to the agreement.
