The Tower of Babel quickly comes to my mind.
My second thought is such a conspicuously large building in a country with millions of starving people just may stir somebody to a point of rage, where they want to bring that ‘useless’ building down to the ground, to stop the wasted government monies. It’s one of the biggest Man Made targets the world has ever seen.
China doesn’t have millions of starving people. It’s not 1948 anymore.
They have rapidly developing obesity problem.
