It's not a blame game among Governments presently.  Last I saw the head lines I battle to see anything on "where Covid-19 started".  Topics we see are mostly on vaccines, and how to get them.  I'd say  all efforts of Governments presently are focused on getting rid of the virus.  I don't see big articles about blaming any one.  Governments are presently fighting one another for access to vaccines - I guess the investigations will catch head lines once Covid 19 is under control again.

That's true.I recently saw a review which saying "China and the U.S. are competing the vaccine developing speed though not widely reported" - this looks interesting.
It is undoubtful that the two countries are on a race - but why they compete on the vaccine?
Case zero reported in Wuhan and actually after sometime there isn't too much attention on this.But if you ever noticed that the governor of Wuhan was dismissed for not applying measures on time,you may found that the news is under control.Media is under pressure.
Okay.Just days before,in my state,some verfied media accounts on GifShow(similar to Tiktok) uploaded videos describing new cases,but just after a day you will found the previous videos were deleted.No reason provided until 3 days later the government says the total number of new cases of that day is wrong.

There will be investigation,but at least citizens like you and me never knows the TRUE result.
