EU, Australia, Argentina? Need I go on?
Nope. EU needs its own fodder internally. If US crops aren't available for export, China will need all Australia can produce, and more. Argentina is mostly beef. FWIW, I grew up on a farm, and my brother farmed as a career, so I have a reasonable background on who produces what, and how much. https://www.investopedia.com/articles/investing/100615/4-countries-produce-most-food.asp
