China lifted its four-year-old ban on U.S. poultry shipments in the latest sign of compromise between the nations as they inch toward a trade deal.

American exports to the Asian country are projected to top $1 billion annually, U.S. Trade Representative Robert Lighthizer and U.S. Secretary of Agriculture Sonny Perdue said in a statement.

“Lifting the ban has been a top priority of the U.S. poultry industry for the past four years,” the National Chicken Council, National Turkey Federation and USA Poultry and Egg Export Council said Thursday in a statement. “This action represents a significant opportunity for U.S. chicken and turkey producers.

At its peak, the annual value of poultry exports from the U.S. to China was $71 million for turkey and $722 million for chicken, the groups said.

A deal over poultry has been one of the areas of advanced discussions between the nations as they negotiate over a partial trade deal. Earlier this month, the U.S. Department of Agriculture said it would remove curbs on Chinese poultry shipments.

The deal is likely to be a major win for U.S. farmers and meat processors. The move comes as African swine fever is destroying the hog herd in China, the world’s biggest pork consumer. The Asian nation has quickly ramped up its meat imports to help meet a protein supply gap.

China prohibited U.S. poultry in 2015 due to an outbreak of highly pathogenic bird flu. Nearly all other nationwide bans following the outbreak have been lifted. Before 2015, U.S. shipments were subject to anti-dumping and anti-subsidy duties.
