Am I missing something?
My first thought is China will poison the food supplies in the United States.
There was a thriller novel (can’t remember the name) by a minor author and the precious wheat supply was destroyed by introduction of an agent that made the wheat shrivel up all over the US during growing season. But Russians had a genuine famine from wheat problems due to weather, so a worldwide loss of millions of lives took place.
It was Heartland by David Hagberg, Tor Books, 1983.
I know that this Virus is part of the plan.
