Hardly. China is also betting on nuclear fission and nuclear fusion:

1. Fission: TMSR-LF1 (a thorium breeder, molten salt research reactor)

Based on US work in 1960s and independent Chinese Sinap work in 1970s. They recently published that they had detected Protactiunium in the salt - a new milestone.

2. Fusion: EAST tokomak

We would all be better off if the US and China just collaborated.

China knows better than to weaken their position in the global theater by having large dependence on other nations for energy. They are aiming for domination and they are well on their way.

Has Nuclear Fusion received massive funding improvements in the last ~12 months?
