China is able to pivot quickly on projects of enormous scale in part due to its political structure. I doubt many western countries would pivot so quickly and drastically for national interests in whatever you call this version of capitalism.
China can CLAIM to pivot quickly on projects, but it is always for show, and most of the funding ends up in pockets of corrupt officials.
The projects end up abandoned and swept under the rug, or end up in failure but reported as successful only to mysteriously never be heard about again.
It's funny how this image built of China to discredit anything they do leads a whole bunch of people online to just completely make stuff up on the spot against any positive news. When it comes to the point that a whole bunch of people are just making stuff up on the spot, we know how efficient the propaganda has been.
