While the US certainly lost business because of this, it’s hard to say that they lost Africa when there’s still huge FDI in Africa [0] even compared to China the US had $50B in 2014-the last year I found both country data- vs China’s $32B. FCPA is 40 years old.
China will surpass the US in Africa, but they’ll surpass the US in everything economic, eventually.
That's how US lost Africa, and China acquired it.
