China imports a gigantic amount of food, and ports were first to be hit by disruption. As a person who works in OEM electronics in China, I can tell at least that.

So, at any normal day, China would've been eating 30-32% of world's food by value, while producing 20% of it by itself.

Agriculture has been on shutdown for the past 2.5 months. Farms have slaughtered a large portion of their livestock, and a big portion of the seedstock has been used for food in the last few months too.

Chinese national reserves were said to be able to keep the country going for 3 months under a strict rationing regime, which we haven't seen, but at least we know by many accounts that meat reserves have been released all across China with no restraint.

Now try guessing how much of it left.

P.S. On ports. I initially wrote them being shut down, I correct that they are facing major disruption, with a lot of ships missing their berthing timeslots
