There's a bit of drama in that there are unofficial reports of two systems in China with higher performance [0], the arXiv paper listed below talks about a 40 million core system with around double theoretical performance than Frontier, and there's apparently a second system online with similar performance. I personally suspect that they didn't submit benchmarks to the top500 simply because those don't run well enough in the systems

I heard they won’t submit anymore so as to not draw further scrutiny and possible sanctions onto their suppliers. Not sure if true, but keeping a low profile certainly makes sense given the blows dealt to the more visible vendors in the past few years.

What are the concerns for vendors?

They also prevent Chinese supercomputing related companies having their chips fabbed in Taiwan.

Let them build those machines and the f they are any good we can steal all their ideas. Turnabout is fair play.
