USA dairy groups appealed to Trump for help after Canada recently introduced a new policy that gives Canadian producers an incentive to buy domestic supplies of ultra-filtered milk, a concentrated ingredient used to boost protein content in cheese and yogurt. Trump went on to say that the issue is another "typical one-sided deal against the United States" and that this latest incident is an example of why the North American Free Trade Agreement fails to keep America's best interest at hand. "The Americans and other countries choose to subsidize to the tunes of hundreds of millions of dollars, if not billions of dollars, their agriculture industries, including their dairy", the prime minister said.
According to Mike von Massow, a professor at the University of Guelph specializing in food economics, the complaints of Wisconsin dairy farmers have nothing to do with supply management - and much more to do with fewer Canadian dairy products entering the American market.

His letter referenced a dairy outlook report from the U.S. Department of Agriculture which he says "clearly indicates the poor results in the U.S. sector are due U.S. and global overproduction".
Indeed, Canada's softwood industry makes no secret of its own search for opportunities in China. "We're going to have to get to the negotiatiing table with Canada very, very quickly", he said.
The work would start immediately, he added.
"Different countries have different approaches, and we're going to engage in a thoughtful, fact-based conversation on how to move forward in a way that both protects our consumers and our agricultural producers", he said. "We're going to get the solution". "Our relationship with the US administration is extremely strong and I think it's going to pay dividends in the long run".
"The whole thing is ridiculous".
"I don't expect there would be many countries that would do anything other than support a WTO action against Canada", said Australian Dairy Farmers interim Chief Executive John McQueen.
