There is also an article about how they did submit a score from one of these Chinese "exaflop" systems, for a different benchmark and it turns out it can only achieve the claimed performance at half precision:

Which would still make it faster than previous number one machine, no?

Maybe not. Fugaku also had super exa scale performance at reduced precision

I suppose we can discuss what the source of the souring of scientific coorperation is. But it does appear that China has at least two computers that are faster than its current best performing entry on the top 500. And that basically invalidates the list.
Allegedly broken this barrier. There is a reason that science is conducted in the open, in a reproducible and traceable manner. Those systems might not function properly at scale, or might not have run at an exaflop in double precision compute.
Frontier is certainly the first publicly verified system to achieve Exascale on the internationally accepted standard measurement.
