That aerial from 2018 is not a true representation of actual deformation of the dam - there is significant visual distortion of that particular satellite view. June 2020 is latest on Google Earth and does not show the distortion.
I concur - just looked at Google Earth, no distortion.
June, 2020 date on the image.

Now who knows how much is propaganda but the video claims that western experts were hired to inspect the dam while it was under construction after quality issues were reported as there was no independent quality function. According to this report their criticism was dismissed as “racial discriminaton”.
The only thing that is certain is “time will tell”.
