Responsible, but not solely responsible. Yes, they withheld information, and absolutely bear blame for every single death outside their borders. The unnecessary deaths in nations that did not react quickly or decisively enough to minimize the threat to their citizens fall on both China and their nation's leaders.

No one owes China anything except sanctions for this. The leaders and officials in other countries whose actions were late and/or or insufficient deserve a reckoning with their people. In the US (and yes, the US is one of those), that comes in November for elected officials and hopefully beforehand for appointed ones.

Yes solely responsible. If they had followed International Law and agreements on this subject it would have been contained within Wuhan.

So, to take this to the extreme, if the Italian government had done nothing at all when things started to go south and instead of there being tens of thousands of deaths there were tens of millions, those deaths would be SOLELY China’s fault?

No, of course not. While no government is responsible for the independent actions of another, every government is responsible for its own response. If that response is insufficient, the government that chose it is responsible for that choice and every life that was needlessly lost as a result of it. That is the weight of governance; actions (or the lack thereof) have consequences, and a government should be held accountable for those consequences.

China did not contain this. Every needless death falls on them. However, as soon as the virus crosses the border into another nation, that nation’s leaders have a responsibility to protect their people. If they do not, those leaders also bear responsibility for any needless deaths within their borders.

This does not lessen the responsibility China bears for unleashing this thing.

The US is not one of those. No, I'm not a US citizen.
I'll just digress at this point because of the obvious BIAS incoming.
Our PM said it was racist to close borders, he relented with proper facts.
There has been way too much politicizing during this crisis and the Left will pay in November.

Funny. “The left will pay in November for politicizing the crisis” just continues to politicize the crisis well beyond its end. Either that, or you agree that political figures who focus on purely political goals rather than on mitigating a crisis should face consequences.

"or you agree that political figures who focus on purely political goals rather than on mitigating a crisis should face consequences." Would be nice for a change but I've been alive too long to expect anything of the Sort.

But you agree that they should. Meaning you agree that a government official’s job to protect the people is far more important than achieving partisan or personal gain.

If you were a US citizen, this pandemic would make voting quite a bit easier for you.

Yes it would.
