"In America, the lack of government support is one reason so many fusion researchers are joining start-ups, Dr. Liu said.
Chinese officials, by contrast, are putting significant resources into a possible “ultimate solution” to humankind’s energy needs"

Great @bradplumer.bsky.social @harrystevens.bsky.social piece on China's nuclear ambition. I'm biased but I think a good satellite comparison is worth 1000 words.
Incidentally, the score for aluminum smelters built since 1990 would be ~50-60 for China, 0 for the US.

A trick for fitting world maps on phones:
Stack two azimuthal equal-area projections, clipped at 90° longitude, each one rotated 180° from the other.
The bottom map covers the top's Antarctica, which reduces the total height and looks nice.
