we are China's second biggest food provider. I think 3 of those 4 categories we are their top provider.
Brazil is the only country who ships them more, and the majority of that is beef alone, not so much on the rest. they will have a rough time replacing the level of food production from the US.
to put some scale on it, the food exports we send to China are more than the total food production of #3 on China's list. Indonesia is #3, total production is 33.5 billion. our food exports to China alone is 50.1 billion.
