In Illinois, pork producers that have increasingly come to depend on the Chinese export market, particularly for cuts of pork less desirable to American consumers, will be hit hard by the Chinese tariff of 25 percent on pork. Buyers in China could turn to other countries as a result. The trade restrictions also could have a ripple effect on corn and soybeans, the two largest crops in the state, as both are used in pork production, according to the farm bureau.
