'Grown'

• Corn, Soybeans - United States
• Rice, Wheat and Fish - China
• Palm Oil - Indonesia

If I am to understand Investopedia correctly, these are the agricultural staples. I am not convinced that I would buy corn from the US or rice from Thailand just because they had invested in their primary industry to this degree. I'm sure there are soy and corn (and wheat) products aplenty from the US despite our ability to grow our own wheat perfectly well. Even in marginal country.
