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.

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".
