First, please read this academic paper for Covid-19 :
The paper indicates the probability for infection : Asian 97%, White and Black people add up only less than 3%
So, you are saying that China produce bio weapon targetting Asians than White and Black people. Does it make any sense to you?
In terms of conspiracy , this strange virus broke out in major city of China, a city which connecting all other major cities, and the timing is right at the period when hundred millions of people moving around China due to Spring festivals. It is also the time when China needs to achieve GDP 5.6%+. Wuhan is also a tech city focusing on military technology, bio technology, space technology, semiconductor technology.
How coincident that Covid-19 has chosen the right place, at the right timing to break out? When too many coincidences happening at the same time, they are not coincidences.
So, lets see it as natural disaster rather than conspiracy.
