As of my knowledge cutoff in September 2021, Achille Mbembe, a prominent Cameroonian philosopher, political theorist, and postcolonial scholar, has written extensively on postcolonialism, power, and the political economy of Africa. However, I don't have specific information regarding his comments on China's pervasive influence in Africa, as his views on this topic may have evolved or been expressed after my knowledge cutoff. It's always recommended to refer to the most recent sources or interviews to obtain the most accurate and up-to-date information on a particular scholar or individual's perspectives.
