There a great documentary called Empire of Dust from 2011 that follows Chinese engineers building roads in the Democratic Republic of the Congo.

https://m.imdb.com/title/tt2148945/

When it gets mentioned online it mostly seems to be racists suggesting Africans are inferior, partly based on the Chinese engineer's frustration with local customs and graft and labour market.

But I found it quite humanising of both the African and Chinese people featured. The director is Belgian, which controlled the region up until independence 50 years before filming.
