China released this Bio-weapon deliberately and timed it to coincide with their Lunar New Year celebrated Globally knowing it would spread rapidly and be slow to display symptoms. They deliberately destroyed evidence, falsified reports and threatened, paid off, bribed or just 'disappeared' anyone who tried to sound a warning.
They forbade travel within their own country while freely allowing their people to travel to the four corners of the Earth. China used its OWN PEOPLE both for 'plausible deniability' and as Disease Vectors knowing they would spread it throughout airports and large populated venues during their long celebratory events infecting others.
They didn't care if it killed millions of their own people because they are overpopulated as it is. China has historically demonstrated it considers its people expendable if it furthers their National or Global aspirations. Plenty more where they came from.
The worse part about it is all the Nations KNOW IT but are either complicit by accepting China's bribes or too chickenshit to hold China accountable because they're financially and politically tied to China's Ass.
