All anxious teeth-grinding about war aside, did it occur to anyone that China's scientists may be taking much more seriously the possible outcome of a massive "Carrington Event"-sized CME this solar maximum than... as yet... the U.S. has? The UK and NZ beefed up their grids to withstand such an event, but China, Russia & the U.S. (for different reasons) have the most vulnerable electric transmission grids in the world - and if/when they go down, those countries will be without grid power (according to their own professional engineers) from 10 months to 4 years.
China's state pragmatism can move faster than the U.S. to set aside for such a disaster, whereas in the U.S. FEMA and DHS have only partnered with NorthCOM to implement martial law nationwide (at least as long as their own food lasts). The Chinese are just ahead of us in planning, that's all.
