China's third world investment adventures are questionable at best. And it would take extraordinary evidence for me to believe in Nigeria's government being competent.
Agreed. Uganda has also received significant investment from China, but the lifespan of the infrastructure apparently leaves some to be desired. The new road to the airport in Kampala is a major improvement, but after a year or two of use is already cracking in some places so may not last as long as one would expect.
That invokes the ship of theseus. China could terraform Nigeria. Megabridges, super housing projects, surveillance, etc.
(Wait this is still the rodney brooks discussion!?)
