Here is my uninformed opinion, feel free to put it with all the other uninformed opinions...
When the Australian Government called for an enquiry into the origins of Covid-19, the Chinese responded with furious rhetoric and slapped Australian products with crippling import duties, then proceeded to slander Australians generally in their social media and all sorts of crazy over the top propaganda.
Why?
Seems to me they are overly defensive about the origins of Covid-19, attacking anyone and everyone who tries to get information.
They also tried in the early stages to cover it up, and persecuted journalists and doctors who tried to raise the alarm. I guess nobody likes bad news.
My conclusion is that the Chinese Government is still in cover-up mode. But rather than covering up evil intent, they are covering up incompetance.
You do have to take into account the different culture in how they handle things. A lot of shit said is geared for it's 'home audience', it's not for us. Chinese are pretty particular about their 'face' (ironically their behaviour is doing the exact opposite which is why Xi Jinping seeing the world opinion of China crash is trying to reign in his 'wolf warrior 'diplomats'). The CCP's face has a pretty thin veneer so any slight against them cuts pretty deep
I think all sides in this whole saga could have handled this way better. When Australian (and others) were calling for an inquiry into the origins of the pandemic, the language and intent was pretty clear it was just wordplay for 'we want to point the finger at the Chinese for this'. Our morally and empathy bankrupt PM should simply keep his mouth shut and leave the talking to diplomats who know how to handle the Chinese with tact and dignity. How you talk to or handle one country may be completely different to how you go about with another country.
When they called for an inquiry, rather than say the focus should be on/in China they should have (even if just for wordplay) say they leave nothing to chance and want to investigate the possibility it could have even started elsewhere but noting China was simply the first to report it (even if you begrudgingly give them a pat on the back for the
eventual reporting). One thing you dont want to do is make China double down on secrecy going forward because they have learnt that being the first country to report an outbreak only leads to that country looking like a villain
Saying you need to know the origins going forward to prepare and equip yourselves better for a possible future pandemic is rubbish. We know it started by a handful of theories. Wild animal to human through wet markets - OK, ban 'wet markets' in the future and also take the possible animals that started it all off every single food menu (such as bats and pangolins)
Maybe started in a lab through an accidental leak? OK, going forward tighten every single SoPs and infrastructure going forward.
These are the 2 dominate theories and the investigation seems to focus on really finding out which one this was. So, just do both. Wet markets are shitty and unnecessary anyway, banning them whether covid started like this or not will vastly reduce the risk to humans going forward. If covid didn't start this way, given time, something will. Bats a friggen nasty. Imagine a lyssavirus like rabies but airborne like covid. Enough to make even the hardest repugnican put on a mask!
And every lab could probably get a good work over to tighten security and controls around them.
