And you said-
"Unfortunately, the second is just dog-whistling and China bashing."
When the article is a report on the SARS virus so not what you implied.But it does say that a similiar corona virus originated in Guangdong so the first article saying that the Covid 19 mutation found in Guangdong was the type A and in Wuhan mostly type B lends weight to Covid 19 being around earlier and possibly originating in Guandong.
And other articles about SARS finding a very similiar corona virus to SARS in horseshoe bats found in caves in Yunan province.
Although the finding of severe acute respiratory syndrome coronavirus (SARS-CoV) in caged palm civets from live animal markets in China has provided evidence for interspecies transmission in the genesis of the SARS epidemic, subsequent studies suggested that the civet may have served only as an...

Chinese scientists find all the genetic building blocks of SARS in a single population of horseshoe bats.

The same bat species has been implicated in Covid 19.
"Prof Shi’s work also challenges the widely held belief that coronaviruses require an intermediate host to make the jump from bats to humans.
To date, it has been accepted that SARS was transmitted from bats to humans via palm civets and, in the case of its cousin MERS (Middle East respiratory syndrome) from bats to humans via camels.
But Prof Shi found something unusual in the people living near the Yunnan cave: 3 per cent had developed immunity to the viruses, proving the strains can and have infected humans in the past.
However, funding for the project dried up and the research into the virus now known to be a close relative to COVID-19 was suspended.
With scientists still unable to identify an intermediate host for COVID-19 (although
snakes and
pangolins have been discussed) the possibility it jumped directly from bats to humans is now being taken very seriously.
“Bats are reservoir hosts of several zoonotic viruses, including the Hendra and Nipah viruses, which have recently emerged in Australia and East Asia,” Prof Shi wrote in her 2005 paper, which identified SARS for the first time."
In 2004, deep in the wilderness of China’s Yunnan province, a group of scientists from the Wuhan Institute of Virology discovered a cave full of wild bats carrying hundreds of SARS-related viruses.

So sorry your dog whistling is totally wrong.
