Not going to go too far into this...yes farmers took a hit. No bueno. The point of the tariffs was in part to send the message to China we can stop feeding them anytime.
Australia was recently threatened economically by China, and they may come to the same conclusion that the US did, and stop feeding China as well. Neither country wants to be bullied by China
China cannot feed itself. Of all the threats to China, this is near the top. They need food imports. If China is perceived and understood to be materially reckless with the virus by the western world, and they decide to sanction and choke China, they can. The implications are huge.
