(Dow Jones) -- Hog farmers are already bracing for lower prices after China this week applied a 25% tariff on imports of US pork, in response to the Trump Administration's tariffs on Chinese steel and aluminum. But President Trump's new list of hundreds more Chinese products targeted for tariffs could squeeze more US crop producers: the list includes Chinese-made machinery for sorting seeds, incubating poultry and preparing animal feed, potentially raising prices for farmers, according to the coalition group Farmers for Free Trade. And, the group says, the new list invites further trade reprisals from China, with US agricultural products widely considered an easy target.
