The Washington Post Monkey Cage published on 18 August 2021 an analysis titled "A Chinese Airport Project in Zanzibar Floundered. Here's What the New G-7 Infrastructure Plan Can Learn" by Veda Vaidyanathan.
The analysis looks at 5 Chinese-built infrastructure projects in Tanzania and Kenya--4 financed by the China Export Import Bank and 1 by the World Bank. The advantages of Chinese projects were high speed, enormous scale, and low costs, although the Zanzibar international airport project experienced major delays and was well over budget.
