The only info I am getting is that an African Diplomat said it but nothing else. I want to use it for the Xi Jingping section of my research paper for Political Science, I think it would add a nice bit of “flavour” for introducing the topic of Chinese relations with African states.
A little web searching suggests it’s usually attributed to “a Kenyan official,” but no one has managed to place it, and consensus has resigned to calling it apocryphal.
