The U.S. Farm Belt braced for deeper pain from the escalating trade battle between the world’s two biggest economies after China said it would suspend all imports of U.S. agricultural goods.

China’s move will affect farmers raising fuzzy green soybean pods in Illinois, milking cows in California and feeding hogs in North Carolina, all of whom have seen business suffer as a result of tariffs that Chinese officials implemented last year.

China’s suspension of U.S. farm purchases is a “body blow” to U.S. farmers and ranchers, said Zippy Duvall, a Georgia farmer and head of the American Farm Bureau Federation. “We urge negotiators to redouble their efforts to arrive at an agreement, and quickly,” he said.

Feeding China’s growing appetite has meant big business for the U.S. farm economy. China was one of the biggest export destinations for U.S. agricultural commodities from 2009 to 2017 alongside Canada and Mexico, according to the U.S. Department of Agriculture. In 2017, Chinese buyers imported $19.5 billion in farm goods.

That dropped to $9.1 billion last year as China’s tariffs on U.S. soybeans, pork, milk and other products made them more expensive for importers there, prompting some to seek alternatives and scale back imports from the U.S. Over the first six months of this year, China’s agricultural imports from the U.S. were down 20% from the same period last year.
