If the West ever entered Africa the way China has the politicians leading it would destroyed at home. It’s more domestic politics and history than geopolitics.
Any economic program set forth by the West and any decisive intervention to stabilize a country is promptly accused of being neocolonialism.
I recall a few years ago there was a military coup in Guinea Bissau and the West stepped in to stabilize the country by getting the Community of Portuguese-speaking countries (Portuguese acronym CPLP) involved and send ground troops. Even so, it was decided that the ground troops needed to be from Angola and leave Portugal to handle logistics because having Portuguese troops on the ground would help the narrative that the former colonizer was controlling the fallen democratic government as a sockpuppet.
