Let me give you a counter argument where we should be thanking China. For a Virus to threaten our entire species it would have to become endemic (everyone carrying it) and then mutate some lethal symptoms in a rapid progression that medical communities can't counter in time.
If a virus gets out and starts making people ill / developing a range of symptoms early then there is more chance it can be detected early, people can take precautions to avoid infection and the virus will eventually run out of steam and either be starved of new infections or inadvertently kill all it's hosts before it can infect everyone.
So you could say that by creating a "Hot house" environment China has exposed the corona virus early in it's evolution and brought it to the world's attention, saving us from a potential extinction level event by creating a horrible pandemic early on in the diseases progression.
It's a natural human response to seek blame, particularly when you hear some of the awful stories now coming out, but ultimately it will not help us to prepare for the next one.
We could not have known for sure it was a respiratory based illness, so I've no problem with a shortage of specialist disease specific equipment like ventilators in this case - that is just the luck of the draw. However, whatever the nature of the next pandemic we face, we can be absolutely sure that we need to have massive stockpiles of high level PPE available to protect Medical and Care staff from infected patients, whatever the nature of the infection, whether airborne, waterborne or through blood / fluid transfer.
