The real hair-raising thing is that HH70 is out of the blue. Three years is a very short period of time to put together a company, supply chain, and working HTS tokamak of any scale. The plasma performance metrics are nearly irrelevant. They've knocked down a lot of difficult questions and paved the way for bigger machines on short timescales. I'm not sure what the next out-of-the-blue headline will be in 3 years, but there's a good chance it will be "burning plasma". The West runs a real risk of being left way behind here.

I wish them best of luck and China speed. It doesn't matter who develops the technology, in either case it's a win for humanity. 7 out of 8 billion people are not in the "west".
