I am sure that if you took the time to make a telephone call to one of the experts in the field of agribusiness at Canadian or American universities with important departments in that field they would tell you this field has big companies quite able to fill any niche needed by the Chinese or anyone else. That is why the profit margins are so low, plenty of producers and they cut profits in order to compete for the business.
Our own Department of Agriculture could probably relate this information as well. The Federal government is there to serve the citizens and has a wealth of information on all kinds of things.
A couple of years ago I was working in Europe and some European police I was working with told me we could not get DNA off shell casings from automatic weapons left at the scenes of ambushes--and often the empty shell casings were the only evidence we had --I called the FBI Crime Lab and they gave me the name of a company near where I live that was getting such DNA taking a little from each shell casing and adding the samples up to a full sample. Just an example of the sort of detailed info the Feds have.
