I'm not sure how to respond to that. The first thing I'd note is quite possibly a certain level of irony when you're saying China's reports are accurate, while simultaneously not being able to access that website from China. The other is that multiple sources other than Johns Hopkins have stated the US has done more testing. I could be wrong, but my supposition on why they're saying that isn't because they think the US' response has been amazing or because they're in love with the administration. But let's play along with the numbers for a moment:That link gives me an error but that might be on my end. I am fairly confident China has done more tests. I was just in Beijing where they did mass testing of about half the city and witnessed it. They have done over 90 million tests. Also producing the vast majority of tests for the world, but that's another issue. Either way your statement or quote that USA has done more tests in July than any other country has overall is incorrect.
Edit: I don't know how USA is testing but China is doing mass testing by panels. Meaning they do 1 test for I think 5-10 people then if it's positive everyone tests individually. So it might be less tests but more people. But still that's not a correct number.
90 million tests? They're reporting that they've had a total of 84,125 confirmed cases. If we were to pretend, for instance, that the specificity for the testing was 99.9% (which is an ungodly generous number), then you'd see 90k cases from false positives alone! So China's either not being forthcoming about 1) the number of cases, 2) the number of tests, or 3) both.
I can't speak for or discount your personal experience of what you've witnessed with regard to testing. But I'd be curious when seeing a lot of testing there, how your ability to quantify that by observation is able to differentiate 100k from 1M from 10M from 200M. It reminds me of this scene from Harry Crumb:
