I watched the video. It shows a Chinese site manager having a confusing interaction with several African workers. He then expresses somewhat racist views to the camera, eg: all Africans are well built because it is a survival of the fittest environment. But I could not follow what you meant by the Chinese perspective. Could you elaborate?
I do recommend watching the documentary in its entirety but there's also an interview with the director that addresses some of the themes in this thread.
