Interesting that the U.S. isn't listed as a country that has built and experimented with a Tokomak reactor.

....since that would make the Chinese experiement look like 30-yr catch-up mode.

Since I'm not a nuclear physicist, someone in another post mentioned that the Chinese are using superconducting magnets. The older, U.S. reactors did not.
