It has more high speed rail than the rest of the world combined.

They own us at literally all infrastructure projects. I visited China in 2023, I went to a small rural town with a small population by China standards (less than 50k) and in my 2 weeks there I saw major road work done that legit would have taken months in my home city in the states. One of the major streets needed work (large holes, uneven, breaking sidewalk, etc etc) it was torn down in one day and rebuilt in 2/3ish, this included the road, the sidewalks, multiple light/power poles.
